Biopolymer-based hydrogels offer a versatile platform for drug delivery thanks to their biocompatibility, use of natural polymers, and tunable properties. In this study, we developed semi-interpenetrating polymer network (semi-IPN) hydrogels composed of alginate (ALG) and chitosan (CS), chemically modified with caffeic acid (CA) and gallic acid (GA), to enhance both antimicrobial and antioxidant activity. The resulting hydrogels showed tunable physical states, high porosity, and good thermal stability, transitioning from liquid dispersions to solid forms under different conditions. Lomefloxacin was loaded to test local delivery performance. Drug release profiles revealed that the modification influenced release: the ALG-CS_CA hydrogel released about 61 % of Lomefloxacin, while the ALG-CS_GA hydrogel released approximately 43 %, in line with their swelling behavior. Incorporation of phenolic acids significantly boosted antioxidant capacity, with the GA-modified hydrogel reaching over 80 % scavenging activity. Tests against Staphylococcus aureus confirmed improved antimicrobial activity compared to unmodified ALG-CS matrices. Overall, these fully bio-based, metal-free semi-IPNs combine biocompatibility, antimicrobial and antioxidant functions, and tunable release properties. This sustainable system, based only on natural polymers and mild chemical functionalization, shows strong potential for safe, scalable biomedical applications in localized therapies for infection-prone or inflamed tissues. This green design offers practical advantages for future scale-up and sustainable production.
基于生物聚合物的水凝胶由于其生物相容性、天然聚合物的使用和可调特性,为药物输送提供了一个通用的平台。在这项研究中,我们开发了半互穿聚合物网络(半ipn)水凝胶,由海藻酸盐(ALG)和壳聚糖(CS)组成,用咖啡酸(CA)和没食子酸(GA)进行化学修饰,以提高抗菌和抗氧化活性。制备的水凝胶具有物理状态可调、孔隙率高、热稳定性好等特点,在不同条件下可从液体分散体转变为固体形态。装载洛美沙星以测试局部递送性能。药物释放曲线显示,修饰影响了释放:ALG-CS_CA水凝胶释放约61%的洛美沙星,而ALG-CS_GA水凝胶释放约43%的洛美沙星,与它们的溶胀行为一致。酚酸的掺入显著提高了抗氧化能力,ga修饰的水凝胶的清除活性达到80%以上。对金黄色葡萄球菌的试验证实,与未经修饰的ALG-CS基质相比,其抗菌活性有所提高。总的来说,这些完全基于生物的,不含金属的半ipn结合了生物相容性,抗菌和抗氧化功能,以及可调节的释放特性。这种可持续的系统仅基于天然聚合物和温和的化学功能化,在易发感染或炎症组织的局部治疗中显示出强大的安全、可扩展的生物医学应用潜力。这种绿色设计为未来的规模扩大和可持续生产提供了实际优势。

As of 2025, the upcycling of vulcanized rubber has emerged as a critical focus in sustainable polymer science, driven by mounting environmental concerns and increasing volumes of end-of-life elastomers, particularly from waste tires. Due to their permanent crosslinked networks and complex additive compositions, vulcanized rubbers remain resistant to conventional recycling. Recent advances have demonstrated promising strategies for their chemical transformation into value-added materials such as activated carbons, electrochemical components, structural composites, and polymeric intermediates. This review consolidates developments in oxidative degradation, pyrolysis, metathesis chemistry, and covalent adaptive networks, with a focus on polybutadiene-based materials. Process limitations, such as feedstock heterogeneity, harsh reaction conditions, and limited circular reintegration, are critically evaluated. Looking ahead, enhanced mechanistic understanding and tailored upcycling pathways are needed to bridge the gap between laboratory research and scalable, sustainable solutions.
截至2025年,受日益严重的环境问题和越来越多的报废弹性体(特别是来自废旧轮胎的弹性体)的推动,硫化橡胶的升级回收已成为可持续聚合物科学的一个关键焦点。由于其永久交联网络和复杂的添加剂组成,硫化橡胶仍然抵抗传统的回收。最近的进展已经证明了将其化学转化为增值材料(如活性炭、电化学组分、结构复合材料和聚合物中间体)的有希望的策略。本文综述了氧化降解、热解、复分解化学和共价自适应网络的研究进展,重点介绍了聚丁二烯基材料。工艺限制,如原料不均一性,苛刻的反应条件,和有限的循环重新整合,严格评估。展望未来,需要加强对机理的理解和量身定制的升级回收途径,以弥合实验室研究与可扩展、可持续解决方案之间的差距。

High-strength lubricating hydrogels combine outstanding mechanical properties (e.g., high compressive/tensile strength) with ultra-low coefficient of friction (COF), while exhibiting biocompatibility, environmental responsiveness, and self-healing capabilities. They are primarily used in artificial joints, surgical instrument coatings, flexible electronics, soft robotics, and industrial lubrication, with particularly promising potential in biomedical and bionic engineering applications. In this review, we first elucidate the fundamental lubrication mechanisms of hydrogels, providing critical insights for their structural design. Subsequently, we systematically summarized the latest advances in high-strength lubricating hydrogels and categorized them based on innovative design strategies, including the design and optimization of overall structures, methods for surface modification, the regulation of lubricating properties and so on. These findings offer a robust framework for developing next-generation bio-lubricating materials with enhanced performance to meet the demanding requirements of practical applications.

Poly(diallyldimethylammonium chloride) (PDADMAC) is a water-soluble cationic polyelectrolyte extensively applied in industrial, environmental, and biomedical systems due to its high charge density and electrostatic functionality. This review consolidates recent advances (2019–2024) in the synthesis, physicochemical properties, and multifunctional applications of PDADMAC, with particular emphasis on antimicrobial interfaces and microbiological performance. PDADMAC enables the fabrication of electrostatically assembled materials, including nanofiltration membranes, hydrogels, and contact-active coatings. Its incorporation into hybrid nanocomposites and biosensors enhances biofilm disruption, pathogen capture, and diagnostic sensitivity. Synergistic effects with antifungal agents have also been reported, especially in potentiation platforms based on PDADMAC. Analytical techniques such as RP-IP LC–ESI-MS support trace-level detection of residual DADMAC monomer in treated water and formulations. In vitro and in vivo studies demonstrate cytocompatibility and wound-healing performance, reinforcing its potential for clinical and environmental use. Applications span membrane functionalization, electrochemical sensing, biomedical coatings, and responsive hydrogels. This review provides a critical framework for researchers and developers working on polyelectrolyte-based functional materials, and highlights emerging opportunities for antimicrobial innovation, toxicological evaluation, and the development of sustainable formulations.

Here, we prepared three types of temperature/pH/redox-responsive diblock copolymers with similar molecular weights, using poly(2-((acrylamidomethyl)(methyl)amino)ethyl ferrocene formate) (P(Fc-N-AM)) as the hydrophobic block and poly(N-isopropylacrylamide) (PNIPAM), poly(ethylene glycol) (PEG), poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) as the hydrophilic block, respectively. Subsequently, their triple-responsive properties were characterized. For temperature-response, they exhibited a lower critical solution temperature (LCST)-type cloud point (CP) in water, and an upper critical solution temperature (UCST)-type CP in ethanol and propanol, and the CP temperature was influenced by the molecular weight and type of the hydrophilic block. For pH-response, all copolymers showed a critical pH in water, and when the molecular weights were similar, their critical pH was also close. The redox-response was confirmed by the reversible change of the characteristic peak of ferrocene (Fc) upon the addition of redox reagents to the solution. Subsequently, these copolymers self-assembled in water to form spherical micelles with different sizes, which also possessed triple stimuli-responsive properties. Finally, by encapsulating Nile Red (NR), the release behavior of NR-loaded micelles under heating, the addition of acid and oxidant were tested. The above studies have enriched the types of temperature/pH/redox triple-responsive polymers, revealed the influence of hydrophilic blocks on the responsive properties and self-assembly behavior of copolymers, and indicated that these copolymers have promising applications in the fields of self-assembly and controlled release.
本文以聚(2-(丙烯酰胺甲基)(甲基)氨基)乙基二茂铁甲酸酯(P(Fc-N-AM))为疏水嵌段,以聚(n -异丙基丙烯酰胺)(PNIPAM)、聚(乙二醇)(PEG)、聚(2-(二甲氨基)甲基丙烯酸乙酯)(PDMAEMA)为亲水嵌段,制备了三种分子量相近的温度/pH/氧化还原响应型二嵌段共聚物。随后,对它们的三重响应特性进行了表征。对于温度响应,它们在水中表现出较低的临界溶液温度(LCST)型云点(CP),在乙醇和丙醇中表现出较高的临界溶液温度(UCST)型云点(CP),并且CP温度受亲水性块的分子量和类型的影响。对于pH响应,所有共聚物在水中都有一个临界pH值,当分子量相近时,它们的临界pH值也很接近。在溶液中加入氧化还原试剂后,二茂铁(Fc)特征峰的可逆变化证实了氧化还原反应。随后,这些共聚物在水中自组装形成不同大小的球形胶束,也具有三重刺激响应特性。最后,通过包封尼罗红(NR),测试了载NR胶束在加热、添加酸和氧化剂等条件下的释放行为。上述研究丰富了温度/pH/氧化还原三响应聚合物的种类,揭示了亲水性嵌段对共聚物响应性能和自组装行为的影响,表明这些共聚物在自组装和控释领域具有广阔的应用前景。

The development of high-performance thermosets with enhanced chemical and mechanical properties is critical for demanding applications. This study reports a novel reactive blending approach to synthesize polybenzoxazine-triazinane copolymers as hybrid thermosets by combining 1,3,5-triazinanes with 1,3-benzoxazines. Polymer networks were prepared via a cost effective and one-pot synthesis using 4,4′-oxydianiline (ODA) and bisphenol A-aniline-based benzoxazine (BA-a). The resulting BA-a/ODA-PHT hybrids exhibit significantly improved acid resistance and 91 % of their mass retained after 30 days in 0.1 M HCl. In contrast, pristine ODA-PHT retained only 40 % by mass. Additionally, the hybrids show a fourfold increase in adhesion to mild steel (4.61 MPa vs. 0.99 MPa for ODA-PHT) and excellent resistance to aggressive liquids, including hydraulic fluids, motor oil, and jet fuel. Thermogravimetric analysis reveals enhanced thermal stability, with a char yield of ∼35 % at 800 °C for BA-a/ODA-PHT. Spectroscopic and thermal analyses including nuclear magnetic resonance (NMR), Fourier-transform infrared (FT-IR), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) were used for further characterizations.
开发具有增强化学和机械性能的高性能热固性材料对于要求苛刻的应用至关重要。本文报道了一种新的反应共混方法,将1,3,5-三嗪烷与1,3-苯并恶嗪结合合成聚苯并恶嗪-三嗪烷共聚物作为杂化热固性聚合物。以4,4′-氧二苯胺(ODA)和双酚a -苯胺基苯并恶嗪(BA-a)为原料,采用一锅法合成了具有成本效益的聚合物网络。得到的BA-a/ODA-PHT杂交种的耐酸性能显著提高,在0.1 M HCl中放置30天后,其质量保留了91%。相比之下,原始ODA-PHT仅保留了40%的质量。此外,混合动力对低碳钢的附着力提高了四倍(4.61 MPa,而ODA-PHT为0.99 MPa),并且具有优异的抗腐蚀性液体性能,包括液压油、机油和航空燃油。热重分析表明,BA-a/ODA-PHT的热稳定性增强,在800°C时炭收率为~ 35%。光谱和热分析包括核磁共振(NMR)、傅里叶变换红外(FT-IR)、差示扫描量热法(DSC)、热重分析(TGA)进行了进一步的表征。

Multi-functional core–shell cylindrical polymer brushes (CPBs) based on polypept(o)ides present an attractive alternative to self-assembled nanoparticles, offering biodegradability and improved structural integrety and complex chemical control over nanoparticle morphology and function. Hence, these structures have been explored for delivery of chemotherapeutics and siRNA, demonstrating their utility as drug carriers. Nevertheless, the synthesis of multifunctional CPBs remains challenging, due to limited chemical compatibility of protecting groups and deprotection conditions, often compromising the chemical integrity of CPB structures. Hence, to address this limitation, we developed a modular and orthogonal sequential ring-opening polymerization (ROP) strategy, enabling the synthesis of well-defined CPBs with benzyl, amine, or carboxyl functionalities. Our results demonstrate that these CPBs possess excellent colloidal stability, tunable hydrodynamic properties, low cytotoxicity, and high biocompatibility, establishing them as robust and adaptable platforms for next-generation drug delivery.
多功能核壳圆柱形聚合物刷(CPBs)是自组装纳米粒子的一个有吸引力的替代品,具有生物可降解性和改进的结构完整性,以及对纳米粒子形态和功能的复杂化学控制。因此,这些结构已被用于化疗药物和siRNA的递送,证明了它们作为药物载体的效用。然而,多功能CPB的合成仍然具有挑战性,由于保护基团的化学相容性有限和去保护条件,通常会损害CPB结构的化学完整性。因此,为了解决这一限制,我们开发了一种模块化和正交顺序开环聚合(ROP)策略,能够合成具有苯、胺或羧基官能性的明确定义的CPBs。我们的研究结果表明,这些CPBs具有优异的胶体稳定性、可调的流体动力学特性、低细胞毒性和高生物相容性,使其成为下一代药物传递的稳健和适应性强的平台。

Block copolymers (BCPs) exhibit unique structures and properties, and are widely applied in industry and fundamental researches. Chemical recycling of BCPs is crucial for environmental protection and the reuse of crude materials. Based on programmed recycling of BCPs, a strategy for the depolymerizations of BCPs is proposed in this research. ABA triblock copolymers (TBCPs) with poly(methyl lipoate) (PLpMe) or poly(penicillamine-derived β-thiolactone) (PNC8-PenTL) outer blocks, PLpMe-b-Pm-b-PLpMe and PNC8-PenTL-b-Pm-b-PNC8-PenTL TBCPs, are synthesized by two-step thiol-phenylsulfone click reactions and thiol-initiated ring-opening polymerizations (ROPs). The outer and middle blocks are sequentially depolymerized using different mechanisms. Two recycling steps are involved in the depolymerization processes. In the first step, PLpMe or PNC8-PenTL blocks are depolymerized to the corresponding monomers through chemical recycling to monomer (CRM). In the second step, the middle blocks Pm are oxidized to sulfoxides/sulfones and the subsequent declick reactions with a thiol compound lead to the depolymerizations of the middle blocks to a value-added compound. The chemical structures of the monomers and the compound produced in the programmed recycling are analyzed by NMR and high-resolution mass spectrometry (HRMS). The changes in the molecular weights of the TBCPs in the two recycling steps are monitored by size exclusion chromatography.
嵌段共聚物(bcp)具有独特的结构和性能,在工业和基础研究中有着广泛的应用。bcp的化学回收对环境保护和原油再利用至关重要。本研究基于bcp的程序化回收,提出了bcp的解聚策略。采用两步硫醇-苯基砜键合反应和硫醇引发开环聚合反应合成了与聚脂酸甲酯(PLpMe)或聚青霉胺衍生β-硫内酯(PNC8-PenTL)外嵌段的ABA三嵌段共聚物PLpMe-b- pm -b-PLpMe和PNC8-PenTL- pm -b-PNC8-PenTL tbcp。外层和中间的块使用不同的机制依次解聚。解聚过程涉及两个回收步骤。在第一步中,PLpMe或PNC8-PenTL区块通过化学回收到单体(CRM)解聚成相应的单体。在第二步中,中间嵌段Pm被氧化为亚砜/砜,随后与硫醇化合物的快速反应导致中间嵌段解聚成增值化合物。利用核磁共振和高分辨率质谱(HRMS)对程序回收过程中产生的单体和化合物的化学结构进行了分析。用粒径排除色谱法监测了两步回收过程中tbcp的分子量变化。

Sulfur-containing polymers are receiving increasing attention due to their unique material and chemical properties, yet access to functional variants remains limited. To address this challenge, the ring-opening terpolymerisation (ROTERP) of phthalic thioanhydride (PTA), carbon disulfide (CS2), and a range of substituted epoxides was investigated. Polymerisation of linear, branched, aromatic, fluorinated, ether-functionalized, and multi-functional epoxides was achieved, thus providing access to a versatile range of sulfur-rich polymers bearing trithiocarbonate functionalities. Most systems exhibited moderate to high sequence selectivity for an alternating poly(ester-alt-ester-alt-trithiocarbonate) terpolymer structure, with some incorporation of polymer links from the competing ring-opening copolymerisation (ROCOP). The materials demonstrated moderate thermal stability under nitrogen (Td,5% up to 314 °C) and tunable glass transition temperatures (Tg ranging from −20 to 163 °C). The trithiocarbonate groups incorporated along the main chain were employed for grafting the polymer chains to gold nanoparticle surfaces, yielding colloidally stable agglomerates. Furthermore, aldehyde-bearing polymers enabled attachment of organic moieties to the polymer grafted-to the nanoparticles via imine condensation, which could be selectively released under acidic conditions. Our study demonstrates the power of ROTERP as a synthetic platform to access a broad catalogue of functional sulfur-containing polymers and nanomaterials from readily available epoxides.
含硫聚合物由于其独特的材料和化学性质而受到越来越多的关注,但其功能变体仍然有限。为了解决这一挑战,研究了邻苯二甲酸硫酐(PTA)、二硫化碳(CS2)和一系列取代环氧化物的开环三聚反应(ROTERP)。实现了线性、支链、芳香、氟化、醚功能化和多功能环氧化物的聚合,从而提供了一系列具有三硫代碳酸盐功能的富硫聚合物。大多数体系对交替聚(酯-醛-酯-醛-三硫代碳酸酯)三元共聚物结构表现出中等至高的序列选择性,其中一些来自竞争性开环共聚(ROCOP)的聚合物链接被掺入。该材料在氮气(Td,5%至314°C)和可调玻璃化转变温度(Tg范围从- 20至163°C)下表现出中等的热稳定性。沿主链结合的三硫代碳酸盐基团用于将聚合物链接枝到金纳米颗粒表面,产生胶体稳定的团聚体。此外,含醛聚合物可以通过亚胺缩合将有机部分附着到接枝到纳米颗粒上的聚合物上,并在酸性条件下选择性释放。我们的研究证明了ROTERP作为一个合成平台的力量,可以从现成的环氧化物中获取广泛的功能性含硫聚合物和纳米材料。

Polyaniline (PANI) is a conducting polymer that captures the attention of researchers due to its properties such as high electrical conductivity, redox activity, environmental stability, and easy synthesis. Therefore, it is widely used for optical, electrochemical, and electronic applications. However, PANI has drawbacks such as limited cycling stability, insolubility in common solvents, and poor mechanical properties. To overcome these drawbacks, researchers have synthesized numerous PANI-based nanocomposites. Number of methods have been reported to synthesize PANI-based nanocomposites. Among them, the electrochemical synthesis is an advanced approach that facilitate the meticulous incorporation of nanomaterial into the PANI polymer matrix through controlled electrochemical processes. Offering precise control, the electrochemical synthesis approach ensures the homogeneous distribution of nanomaterial within the resulting nanocomposite. The homogeneity of the nanocomposite effectively enhances the properties such as mechanical strength, conductivity, corrosion inhibition, sensor performance, capacitance, and cycling stability. Furthermore, the process utilizes less sophisticated equipment, minimizes material wastage, and operates under mild conditions, making it environmentally friendly. Therefore, electrochemical synthesis emerges as a powerful and versatile approach for efficient and customizable synthesis of PANI-based nanocomposites with broad applications in diverse technological fields. This review discusses electrochemical synthesis methods used to fabricate PANI-based nanocomposites, with a focus on the experimental parameters and conditions. It aims to provide insights that can guide future experimental design and optimization.
