Despite their significant contribution to wearable electronic applications, conductive textiles face practical performance limitations due to the intrinsically insulating nature of textile fibers and the poor durability, adhesion, and low conductivity of traditional conductive polymer coatings. Materials like PEDOT: PSS, polypyrrole, graphene, and metal nanoparticles, all of which coat fibrous substrates non-uniformly, resulting in poor charge transport and high contact resistance. Unfortunately, these failures lead to rapid degradation in terms of either shortening the service life of electrical performance under mechanical deformation, washing, or long-term use. It limits their integration in reliable sensors, energy-harvesting devices, and health monitoring systems. This review demonstrates how cold plasma techniques are used to address such persistent drawbacks. Plasma-induced functional groups enhance the surface energy and introduce nanoscale roughness to provide strong adhesion interface with coatings while producing improved interfacial bonding. Thus, conductive polymers, MXenes, and metal-polymer nanocomposite coatings through plasma-assisted deposition exhibit comparatively less electrical resistance with superior mechanical properties, retaining the flexibility and breathability of the fabric. Additionally, the plasma-enabled coatings confer multifunctional properties such as antibacterial, photothermal, and stable bio signals in sensing. The review finally identifies future challenges-enhanced scalability, long-term electrical stability under extreme conditions, and a sustainable process-while highlighting emerging opportunities associated with plasma-engineered textiles for next-generation smart wearables.

尽管导电纺织品对可穿戴电子应用做出了重大贡献，但由于纺织纤维的固有绝缘性质以及传统导电聚合物涂层的耐久性、附着力和导电性差，导电纺织品面临着实际性能的限制。像PEDOT: PSS、聚吡咯、石墨烯和金属纳米颗粒等材料，所有这些材料都不均匀地覆盖在纤维基板上，导致电荷传输不良和高接触电阻。不幸的是，这些故障导致在机械变形，洗涤或长期使用下缩短电气性能使用寿命方面的快速退化。它限制了它们在可靠的传感器、能量收集设备和健康监测系统中的集成。这篇综述展示了如何使用冷等离子体技术来解决这些持续存在的缺点。等离子体诱导的官能团增强了表面能，并引入了纳米级的粗糙度，为涂层提供了强大的粘附界面，同时改善了界面结合。因此，导电聚合物、MXenes和金属-聚合物纳米复合涂层通过等离子体辅助沉积表现出相对较小的电阻和优越的机械性能，保持了织物的柔韧性和透气性。此外，等离子体涂层具有多种功能，如抗菌、光热和稳定的传感生物信号。该评估最后确定了未来的挑战-增强的可扩展性，极端条件下的长期电气稳定性以及可持续的过程-同时强调了与下一代智能可穿戴设备的等离子工程纺织品相关的新兴机会。

This study investigates a method to regulate the foaming effect, enhance foam stability and overall performance of chemically foamed aerated geopolymer concrete (AGC) using recycled waste latex paint (RWP). The RWP consists of acrylic polymers and surfactants which are expected to regulate the foaming effect in AGC. AGC was synthesised by alkali activation of fly ash and slag, with Aluminium powder as the chemical foaming agent. A varying level of RWP was introduced as the foam regulating agent to enhance the rheological properties and gas bubble distribution in the AGC matrix. The systematic experimental analysis revealed that higher RWP dosage increased the expansion height by 75 % with a well-regulated expansion behaviour, attributed to the presence of soluble polymers and surfactants in RWP that mitigate bubble collapse and enhance the chemical foam stability. Additionally, increased RWP dosage improved the viscosity and yield strength of AGC mixes, facilitating better gas bubble migration in the matrix, resulting in finer and uniform pore structure. High RWP content increased porosity by 31 % and reduced density by 35 %, indicating its efficiency in producing lightweight AGC products. Although a reduction in the compressive strength of about 40 %–75 % was observed due to increased pore connectivity and reduced geopolymerisation from pigments and impurities in RWP, microstructural analysis confirmed reduced bubble coalescence and pore irregularity. Enhanced interfacial paste strength resulted in a finer and more uniform pore distribution. These findings demonstrate the potential of RWP as a value-added, sustainable additive for producing lightweight, non-load bearing AGC products with enhanced thermal and acoustic properties, contributing to sustainable construction and promoting the circular economy of waste paint products.

本研究探讨了利用再生废乳胶漆（RWP）进行化学发泡加气地聚合物混凝土（AGC）的发泡效果调控、泡沫稳定性和综合性能提高的方法。RWP由丙烯酸聚合物和表面活性剂组成，它们有望调节AGC中的发泡效果。以粉煤灰和矿渣为原料，以铝粉为化学发泡剂，采用碱活化法制备了AGC。加入不同水平的RWP作为泡沫调节剂，改善AGC基体的流变性能和气泡分布。系统的实验分析表明，较高的RWP用量使膨胀高度提高了75% %，并具有良好的调节膨胀行为，这归因于RWP中可溶性聚合物和表面活性剂的存在，这些聚合物和表面活性剂减轻了气泡的破裂，增强了化学泡沫的稳定性。此外，RWP添加量的增加提高了AGC混合物的粘度和屈服强度，促进了气泡在基体中的迁移，使孔隙结构更细、更均匀。高RWP含量可使孔隙率提高31% %，密度降低35% %，表明其在生产轻质AGC产品中的效率。虽然观察到由于RWP中色素和杂质的孔隙连通性增加和地聚合减少，抗压强度降低了约40% % - 75% %，但微观结构分析证实了气泡聚并和孔隙不规则性的减少。界面膏体强度增强，孔隙分布更细、更均匀。这些发现证明了RWP作为一种增值的、可持续的添加剂的潜力，可用于生产具有增强热和声学性能的轻质、非承重AGC产品，为可持续建筑做出贡献，并促进废弃涂料产品的循环经济。

Vitrimers represent a transformative class of polymeric materials that combine the robust mechanical properties of thermosets with the reprocessability of thermoplastics. Among them, bio-based vitrimers have garnered increasing attention as a sustainable alternative to conventional petrochemical-derived networks, aligning with the principles of green chemistry and circular economy. This article provides a comprehensive overview of bio-based vitrimers, beginning with an introduction to their fundamental chemistry and dynamic covalent network architecture. Key associative exchange mechanisms such as transesterification, transamination, disulfide exchange, etc are discussed. A detailed examination of monomers derived from renewable sources, including epoxidized plant oils, lignin derivatives-based building blocks, is presented to highlight the versatility and eco-friendliness of feedstock options. The resulting vitrimers exhibit a wide range of desirable properties, including recyclability, self-healing, thermal stability, solvent resistance, and shape memory behavior. Despite their promise, challenges such as limited scalability, cost-effectiveness, and trade-offs between mechanical strength and dynamic behavior remain. Finally, the future outlook of vitrimer research is discussed, focusing on developing new dynamic chemistries, enhancing biocompatibility, and integrating smart functionalities for advanced applications in aerospace, biomedical, and electronic sectors. This review underscores the significant potential of bio-based vitrimers to reshape sustainable materials science while addressing the pressing need for circular material lifecycles.

Ceria co-doped with Ni and Mg (Ni, Mg@CeO₂) was examined for its electrochemical performance, showing impressive power density and cyclic stability in the fabricated device. The material was synthesized using an easy, low-cost solution combustion method. Two different materials were studied to evaluate the impact of co-doping: pristine CeO₂/AC (M − 1) and Ni, Mg@CeO₂ composite with AC (Activated Carbon) (M − 2). Structural analysis confirmed the face-centered cubic (FCC) structure of CeO₂ through X-ray diffractometry (XRD). The structural and optical properties were characterized by using field-emission scanning electron microscopy (FESEM) and photoluminescence (PL) spectroscopy, respectively. The electrochemical behavior was tested with cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS), revealing the pseudocapacitive nature of the ceria-based electrodes. As an electrode material, CeO₂/AC (M − 1) achieved a higher specific capacitance (C_s) of 244.4 F/g at 0.5 A/g, while Ni, Mg@CeO₂/AC (M − 2) showed 197.6 F/g at the same current. In a full-device setup, Ni, Mg@CeO₂//AC (M − 2) reached a C_s of 63.3 F/g at 0.5 A/g, along with excellent cycling stability, retaining 100.4 % coulombic efficiency over 5000 GCD cycles. The hybrid device based on Ni, Mg@CeO₂//AC displayed a maximum specific energy of 18.3 Wh/kg and a specific power of 467.5 W/kg at 0.5 A/g.

Bacterial cellulose (BC) is a high-performance bio-derived material with growing relevance to circular manufacturing in environmental remediation, biodegradable, compostable packaging, biomedical scaffolds, and wearable/flexible electronics. Unlike petroleum plastics and even many plant-cellulose derivatives, BC is secreted as an ultra-pure (>99 %) nanoscale fibrillar network of 20–100 nm size with high crystallinity, tensile strength on the order of 200–400 MPa, tunable porosity, and intrinsic biocompatibility. This review consolidates advances in: (i) CRISPR/base-editing and programmable promoter engineering to boost yield and embed functionality in situ; (ii) intensified and hybrid reactor concepts that overcome oxygen-transfer and shear limitations; and (iii) AI-/ML-guided fermentation control, which is already demonstrating 20–25 % cost reduction through optimized media, pH control, and aeration. A central theme is the use of agro-industrial residues like fruit peels, whey, distillery/winery effluent, bagasse as carbon sources to displace refined sugars, reduce waste management burdens, and close material loops within a circular biorefinery model. We critically evaluate BC composite systems (e.g., MXene/BC electrodes, antimicrobial wound dressings, high-barrier bioplastic films) and identify barriers to scale, including inhibitor carryover from waste feedstocks, fouling, water-vapor transmission rate, phenolic coloration, and clinical regulatory constraints. Finally, we propose a translational roadmap built on data-rich bioreactors, modular waste-to-value integration, and application-specific surface functionalization to accelerate industrial deployment of BC as a next-generation sustainable material.

细菌纤维素（BC）是一种高性能的生物衍生材料，在环境修复、可生物降解、可堆肥包装、生物医学支架和可穿戴/柔性电子产品的循环制造中具有越来越重要的意义。与石油塑料和许多植物纤维素衍生物不同，BC是一种超纯（>99 %）纳米级纤维网络，尺寸为20-100 nm，结晶度高，抗拉强度在200-400 MPa量级，孔隙率可调，具有内在的生物相容性。本文综述了以下方面的进展：(i) CRISPR/碱基编辑和可编程启动子工程，以提高产量和原位嵌入功能；克服氧传递和剪切限制的强化和混合反应器概念；（iii） AI / ml引导的发酵控制，通过优化培养基、pH控制和曝气，已经证明成本降低了20-25 %。一个中心主题是利用果皮、乳清、酿酒厂/酒厂废水、甘蔗渣等农业工业残留物作为碳源来取代精制糖，减轻废物管理负担，并在循环生物炼制模式内实现物质循环。我们批判性地评估了BC复合系统（例如，MXene/BC电极、抗菌伤口敷料、高屏障生物塑料薄膜），并确定了阻垢障碍，包括废物原料的抑制剂携带、污染、水蒸气透过率、酚类着色和临床监管限制。最后，我们提出了一个基于数据丰富的生物反应器、模块化废物到价值集成和特定应用表面功能化的转化路线图，以加速BC作为下一代可持续材料的工业部署。

A condensation reaction between an isocyanate and polyols produces a synthetic polymer, polyurethane (PU). Owing to its complex chemical framework, PU is highly recalcitrant. This plastic type consists of hard and soft segments in its structure, which critically influence its mechanical properties and functional versatility. Its inherent structural complexity and resistance to degradation have created significant challenges in its end-of-life management, contributing to persistent plastic pollution. In recent years, microbial-mediated enzymatic degradation has emerged as a promising alternative to conventional waste treatment and disposal strategies. This review provides a comprehensive overview of PU biodegradation, outlining the polymer's chemistry, the role of microbial communities and their associated enzymes, and emerging insights from metabolic pathway analysis to molecular-based metagenomic studies. Standardized testing methods and analytical techniques are evaluated along with physicochemical and environmental factors that influence degradation. Recent innovations like the development of engineered microbial consortia, enzyme optimization strategies, pre-treatment methods, and bio-based formulations collectively advance PU biodegradation and support sustainable material valorisation.

Recently, the power conversion efficiency (PCE) of organic solar cells (OSCs) has been reported over 19 % due to the development of novel electron donor polymers and acceptor molecules such as PM6:Y6. In addition, cathode interlayers (CILs) based on non-fullerene structure (e.g., PNDIT-F3NBr and PDINN) have been employed in conventional OSCs to facilitate charge transfer from the active layer to electrode. However, metal electrodes for cathode contact have received relatively little attention and the role of the CIL/metal interface has been barely investigated in OSCs. While conventional OSCs generally adopt a low work function cathode (e.g., silver and aluminum) for an ideal energy positioning near the LUMO of the active material, in this study, gold (Au) with a high work function is utilized as the top electrode, which is rarely explored, resulting in a high open circuit voltage of 0.853 V and PCE of 14 % based on a device structure with ITO/PEDOT:PSS/PM6:Y6/PNDIT-F3N-Br/Au. X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS) reveal a significant upward shift of the apparent work function of Au (ΔΦ_Au > 1.0 eV) at the CIL/Au interface, leading to a suitable energy level alignment for charge extraction and efficient device operation. On the other hand, Au diffusion into the PM6:Y6 active blend results in poor long-term stability of OSCs, as evidenced by grazing incidence wide angle X-ray scattering (GIWAXS) and impedance spectroscopy (IS).

近年来，由于新型电子给体聚合物和受体分子如PM6:Y6的发展，有机太阳能电池（OSCs）的功率转换效率（PCE）已超过19% %。此外，基于非富勒烯结构的阴极中间层（CILs）（例如PNDIT-F3NBr和PDINN）已被用于传统的OSCs中，以促进电荷从活性层转移到电极。然而，金属电极作为阴极接触电极受到的关注相对较少，并且对金属界面的作用几乎没有研究。传统的OSCs通常采用低功函数阴极（如银和铝）来实现在活性材料LUMO附近的理想能量定位，而在本研究中，采用具有高功函数的金（Au）作为顶电极，很少进行探索，基于ITO/PEDOT:PSS/PM6:Y6/PNDIT-F3N-Br/Au的器件结构，获得了0.853 V的高开路电压和14 %的PCE。x射线光电子能谱（XPS）和紫外光电子能谱（UPS）显示，在CIL/Au界面处，Au的视在功函数（ΔΦAu > 1.0 eV）明显向上移动，导致合适的能级对准，从而实现电荷提取和高效的器件运行。另一方面，Au在PM6:Y6活性混合物中的扩散导致osc的长期稳定性较差，掠入射广角x射线散射（GIWAXS）和阻抗谱（IS）证明了这一点。

The oilfield industry faces significant challenges, such as high raw material costs and negative environmental impacts due to the widespread use of synthetic oilfield chemicals sourced from petrochemicals. The reliance on environmentally hazardous synthetic oilfield chemicals contributes to severe global issues, including carbon emissions, global warming, and climate change, posing potential threats. Therefore, ongoing research is increasingly directed toward the development of oilfield chemicals derived from natural sources, particularly plant-based extracts—an approach commonly known as "green oilfield chemicals." Among these, cashew nut shell liquid (CNSL), a key plant-derived material and low-cost byproduct of the cashew industry, has emerged as a promising and economically viable alternative to conventional feedstocks. So far, numerous chemicals and value-added products have been generated from CNSL, establishing its applications across various industries. This review provides a comprehensive overview of recent advancements in CNSL-based oilfield applications, including fuel, crude oil-water emulsions, emulsifiers and demulsifiers, flow improvers for waxy crude oil, corrosion inhibitors, lubricants, enhanced oil recovery (EOR), surfactants and foaming agents, with an emphasis on chemical structure–function relationships. We further present a comparative life-cycle assessment (LCA) of CNSL-based versus conventional oilfield chemicals, highlighting their potential environmental and sustainability benefits. Finally, we discuss market trends in green energy, technological opportunities, challenges, and future research directions aimed at improving reproducibility, scalability, and industrial adoption of CNSL-based additives. By integrating chemical, environmental, and economic perspectives, this review offers a forward-looking roadmap for the advancement of bio-based materials in the oilfield industry.

Additive manufacturing (AM) is becoming an important route for creating piezoelectric materials and devices with application-driven geometries, spatially programmed functionality, and compatibility with flexible or wearable platforms. Recent progress has extended AM from simple polymer sensors to ceramic, polymer, and ceramic–polymer composite systems based on jetting, liquid resin–based printing (SLA, DLP, CLIP), extrusion or direct ink writing (DIW), powder-based processes, and emerging multi-material platforms. A central viewpoint of this review is that the electromechanical performance of 3D printed piezoelectrics depends on both the intrinsic material system (such as PZT, BTO, KNN, PVDF and PVDF-TrFE) and the way AM process parameters shape the microstructure through ink or feedstock formulation, printable feature size, curing or sintering depth, layer adhesion, and poling conditions. By organising the literature along this process–structure–property chain, different AM process can be compared on the same basis. Liquid resin–based and DIW methods at present provide the most practical balance between tens-of-micrometres resolution, shape fidelity, and compatibility with ceramic-filled or PVDF-based inks. Jetting and aerosol-jet printing are well suited to patterned thin active layers but remain highly sensitive to ink formulation. Powder-based processes still need better densification control to reach high d₃₃ lead-free ceramics. AM-oriented structural designs, including multilayer stacks, porosity-graded or multiphase lattices, and compliant substrates, can improve sensitivity, durability, and energy harvesting efficiency by matching mechanical impedance and promoting dipole alignment. Remaining challenges include printable high solid loading lead-free systems, stable dispersion and interfacial adhesion at low temperatures, predictive models that link print paths to poling response, and the absence of standardized benchmarking across AM platforms. The integration of data-driven optimization and in situ monitoring with this AM process is identified as an effective way to shorten the ink-to-device iteration cycle and to deliver reproducible, application-specific 3D printed piezoelectric devices.

增材制造（AM）正在成为制造具有应用驱动几何形状、空间编程功能以及与柔性或可穿戴平台兼容的压电材料和器件的重要途径。最近的进展已经将增材制造从简单的聚合物传感器扩展到陶瓷、聚合物和陶瓷-聚合物复合系统，这些系统基于喷射、基于液体树脂的印刷（SLA、DLP、CLIP）、挤出或直接墨水书写（DIW）、基于粉末的工艺和新兴的多材料平台。本综述的中心观点是，3D打印压电材料的机电性能取决于固有材料系统（如PZT、BTO、KNN、PVDF和PVDF- trfe）以及增材制造工艺参数通过墨水或原料配方、可打印特征尺寸、固化或烧结深度、层粘结力和极化条件来塑造微观结构的方式。通过沿着这个过程-结构-属性链组织文献，可以在相同的基础上比较不同的AM过程。目前，基于液体树脂和DIW的方法在几十微米分辨率、形状保真度和与陶瓷填充或pvdf基油墨的兼容性之间提供了最实用的平衡。喷射和气溶胶喷射印刷非常适合于有图案的薄活性层，但对油墨配方仍然高度敏感。粉末工艺仍需要更好的致密化控制，以达到高d33无铅陶瓷。面向am的结构设计，包括多层堆叠、孔隙度梯度或多相晶格以及柔性衬底，可以通过匹配机械阻抗和促进偶极子排列来提高灵敏度、耐久性和能量收集效率。其余的挑战包括可打印的高固体负载无铅系统，低温下稳定的分散和界面粘附，将打印路径与极点响应联系起来的预测模型，以及缺乏跨增材制造平台的标准化基准。数据驱动优化和现场监测与AM工艺的集成被认为是缩短油墨到器件迭代周期和提供可重复的、特定应用的3D打印压电器件的有效方法。
