Thermoset polymers are employed as matrices for fiber-reinforced composite materials due to their outstanding thermo-mechanical and chemical properties. However, the irreversible nature of their covalently crosslinked network makes conventional recycling methods unsuitable for their efficient and economically competitive reprocessing. Moreover, the most common thermoset systems typically rely on depletable and often hazardous fossil-based sources. Vitrimers have been introduced in recent years to offer potential advantages over traditional thermosets, as they can mitigate some of these issues thanks to their three-dimensional covalent network, able to undergo temperature-activated dynamic bond-exchange reactions leading to topological rearrangement. As the environmental concerns about the end-of-life of materials are paired with the need to replace fossil-based resources, research is moving towards the formulation of vitrimeric composites obtained from biobased constituents. This work employed an algae-derived epoxy resin (phloroglucinol triglycidyl ether) with glutaric anhydride to develop an easy-reprocessable, catalyst-free vitrimer for the production of glass fiber-reinforced composites. The vitrimeric behavior of these systems was assessed via rheological stress relaxation, which was found to be fast at moderately high temperatures (3 min at 200 °C, 100 min at 120 °C) and could be repeated multiple times due to the high chemical reversibility of the network. The resin was then employed as matrix for a thermoformable and weldable glass fiber-reinforced laminate with excellent adhesion strength (54 MPa) and easy chemical recyclability in mild conditions (150 °C, ambient pressure). Finally, the enhanced circularity of the produced composite was compared to a standard thermoset counterpart employing the Material Circularity Indicator.

热固性聚合物由于其优异的热机械和化学性能而被用作纤维增强复合材料的基体。然而，它们共价交联网络的不可逆性使得传统的回收方法不适合它们的高效和具有经济竞争力的再处理。此外，最常见的热固性系统通常依赖于可消耗且往往危险的化石源。近年来，与传统热固性聚合物相比，玻璃聚合物具有潜在的优势，因为它们具有三维共价网络，能够进行温度激活的动态键交换反应，从而导致拓扑重排，从而减轻了这些问题。由于对材料寿命结束的环境担忧与替代化石基资源的需求相结合，研究正朝着从生物基成分中获得的玻璃体复合材料的配方发展。这项工作采用藻类衍生的环氧树脂（间苯三酚三甘油酯醚）和戊二酸酐来开发一种易于再加工、无催化剂的玻璃体，用于生产玻璃纤维增强复合材料。通过流变应力松弛来评估这些体系的玻璃化行为，发现在中等高温下快速（200°C下3分钟，120°C下100分钟），并且由于网络的高化学可逆性，可以重复多次。然后将该树脂用作热成型和可焊接的玻璃纤维增强层压板的基体，该层压板具有优异的粘合强度（54 MPa），并且在温和条件下（150°C，环境压力）易于化学回收。最后，生产的复合材料的增强圆度与采用材料圆度指标的标准热固性对应物进行比较。

The accumulation of non-degradable chloroprene rubber (CR) causes detrimental environmental concerns. In this work, deconstruction of CR (i.e., CR240T) and upcycling of CR240T with norbornene (NBE) through olefin metathesis reaction using the second-generation Grubbs catalyst (G2) are investigated. Experimental results show that the number-averaged molar mass (M_n) of deconstruction product (DCR) decreases from 136 to 21 kDa with the increase of G2 concentration. Meanwhile, deconstruction mechanism becomes more complex from the cross-metathesis with G2 dominated to the cross-metathesis and ring-closing metathesis (RCM) reaction coexisted. Besides, concurrent ring-opening metathesis polymerization of norbornene (NBE) and macromolecular cross-metathesis between CR240T and PNBE enables the synthesis of CR and PNBE multiblock-like copolymer (CRNBE). The M_n of the resulting CRNBE increases as NBE concentration increases or G2 concentration decreases. The copolymers CRNBE_0.5 and CRNBE₁ own much higher Young’s modulus as 91.0 ± 3.9 MPa and 347.8 ± 16.7 MPa, respectively, compared to that of the pristine CR240T (28.1 ± 2.7 MPa). This study provides meaningful insights into the deconstruction mechanism of CR via metathesis reaction and a facile way for its upcycling.

不可降解的氯丁橡胶（CR）的积累引起了有害的环境问题。本研究采用第二代Grubbs催化剂（G2）对CR（即CR240T）进行解构，并通过烯烃复分解反应将CR240T与降冰片烯（NBE）进行升级回收。实验结果表明，随着G2浓度的增加，分解产物（DCR）的数平均摩尔质量（Mn）从136 kDa减小到21 kDa。与此同时，解构机制也从G2主导的交叉复分解发展为交叉复分解与合环复分解（RCM）反应并存。此外，通过降冰片烯（NBE）的开环复合聚合以及CR240T与PNBE之间的大分子交叉复合反应，可以合成CR与PNBE多嵌段共聚物（CRNBE）。所得CRNBE的Mn随NBE浓度的增加或G2浓度的降低而增加。共聚物CRNBE0.5和CRNBE1的杨氏模量分别为91.0±3.9 MPa和347.8±16.7 MPa，远高于原始CR240T（28.1±2.7 MPa）。本研究为CR的分解机理提供了有意义的见解，并为其升级回收提供了便捷的途径。

In this study, four triazatruxene-based donor molecules TAT, TAT-H, TAT-HBr, and TAT-TY1 were used in combination with diphenyliodonium hexafluorophosphate under simulated sunlight for cationic polymerization. Irradiation was provided by a solar simulator that mimics the sunlight was equipped with a metal halide lamp (300–3000 nm), and the intensity was adjusted to 100 mW·cm⁻² using a calibrated silicon solar cell (CalLab, Fraunhofer ISE, Germany; active area: 4 cm²). Notably, all triazatruxene derivatives acted as sensitizers for diphenyliodonium hexafluorophosphate, significantly extending the absorption window of the onium salt into the visible region. These photosensitizers exhibited red-shifted maximum absorption wavelengths of 377, 397, 405, and 460 nm, respectively. The underlying chemical mechanisms were investigated using fluorescence spectroscopy and cyclic voltammetry. The proposed mechanism involves photoinduced electron-transfer reactions between the excited donor molecules and diphenyliodonium hexafluorophosphate ions. The cationic polymerization of the epoxy monomer (bisphenol A epoxy resin) is initiated by radicals and Brønsted acids. Among the sensitizers, TAT-TY1 demonstrated the highest efficiency under simulated sunlight, yielding a higher final monomer conversion (∼90%) and a shorter onset time (15 min). The resulting polymers were characterized by gel permeation chromatography, and the TAT-TY1 system produced the highest molecular weight and the broadest molecular weight distribution.

本研究将四种三氮祖蒽基给体分子TAT、TAT- h、TAT- hbr和TAT- ty1与六氟磷酸二苯硫鎓在模拟阳光下进行阳离子聚合。采用金属卤化物灯（300-3000 nm）模拟太阳光的太阳模拟器进行照射，使用校准过的硅太阳能电池（德国Fraunhofer ISE， CalLab，有效面积：4 cm2）将照射强度调节为100 mW·cm - 2。值得注意的是，所有三氮卓苯衍生物都是二苯六氟磷酸钠的增敏剂，显著延长了铵盐在可见光区域的吸收窗口。这些光敏剂的最大吸收波长分别为377、397、405和460 nm。利用荧光光谱和循环伏安法研究了其潜在的化学机理。所提出的机制涉及激发的供体分子与六氟二苯硫鎓离子之间的光诱导电子转移反应。环氧单体（双酚A环氧树脂）的阳离子聚合是由自由基和溴化酸引发的。在这些增敏剂中，TAT-TY1在模拟阳光下表现出最高的效率，产生更高的最终单体转化率（约90%）和更短的起效时间（15分钟）。用凝胶渗透色谱法对所得聚合物进行了表征，结果表明TAT-TY1体系分子量最高，分子量分布最广。

To develop a sustainable and compatible plasticizer for polylactide (PLA), lactide oligomers (LOs) with full biocarbon were synthesized through bulk ring-opening polymerization, initiated by tetrahydrogeraniol. The effects of lactic acid chain length (4, 12, 24 theoretical repeating units) and terminal group (tetrahydrogeranyl and ethyl) on plasticization efficiency were studied. It was determined that the plasticization efficiency decreased with the increase in repeating units and the decrease in terminal alkyl chain length, which could be explained by the strengthened interactions. The LOs have good compatibility with PLA, which can be seen from the high transparent appearance of PLA blends, no phase separation in morphology, one glass transition temperature, low migration rate (<1 % in water, n-hexane and 70 °C) and good durability (performance can be maintained more than 90 days). Tetrahydrogeraniol-initiated lactide oligomer with 4 repeating lactic acid units (TLO4) exhibits higher plasticization efficiency and better durability than commercial acetyl-tri-n-butyl citrate. The elongation at break of the PLA blend is remarkably increased by adding 10 wt% TLO4 (323.9 %) and can further reach 453.1 % (20 wt% loading), with a low glass transition temperature at 32 °C. The crystallization ability of PLA was enhanced by a small amount of LOs, without a noticeable increase in crystallization rate. The molecular dynamics simulation was used to help understand the plasticization mechanism of LOs. This study adds a new choice to the environmentally friendly plasticizers for PLA and may be helpful for the further development of sustainable additives for PLA.

为了开发一种可持续兼容的聚丙交酯（PLA）增塑剂，以四氢香叶醇为引发剂，通过本体开环聚合合成了具有全生物碳的聚丙交酯低聚物（LOs）。研究了乳酸链长（4、12、24个理论重复单元）和末端基团（四氢香叶基和乙基）对塑化效率的影响。结果表明，随着重复单元的增加和末端烷基链长度的减小，塑化效率降低，这可以解释为相互作用的增强。LOs与PLA具有良好的相容性，这可以从PLA共混物的高透明度外观，形貌上无相分离，一次玻璃化转变温度，低迁移率（在水，正己烷和70℃中为<； 1%）和良好的耐久性（性能可保持90天以上）中看出。具有4个重复乳酸单元的四氢香叶醇引发的丙交酯低聚物（TLO4）比商品柠檬酸三丁酯具有更高的塑化效率和耐久性。加入10 wt% TLO4（323.9%）后，PLA共混物的断裂伸长率显著提高，进一步达到453.1% （20 wt%负载），玻璃化转变温度较低，为32℃。少量的LOs增强了PLA的结晶能力，但结晶速率没有明显提高。通过分子动力学模拟，了解了LOs的塑化机理。本研究为环保型聚乳酸增塑剂提供了新的选择，对进一步开发可持续发展的聚乳酸助剂具有一定的指导意义。

Heavy-metal-derived oxoanions are major contributors to water contamination, posing serious threats to both the environment and human health. The selective and efficient removal of these oxoanions from water remains a significant scientific and technical challenge. Leveraging the inherent advantages of cationic porous organic polymers (POPs) for anion capture, we report a three-dimensional cationic POP, TEPM-BPymPh, constructed from tetraphenylmethane and bispyridinium-phenylene monomers via two synthetic approaches: direct Sonogashira cross-coupling and post-cyclization of the neutral precursor TEPM-BPyPh. Owing to its high charge density and ion-exchange properties, TEPM-BPymPh effectively adsorbs toxic oxoanions, including MnO₄⁻, ReO₄⁻, CrO₄²⁻, and Cr₂O₇²⁻, from aqueous solutions. In particular, it exhibits an exceptional adsorption capacity for MnO₄⁻ (454 mg g⁻¹), along with excellent selectivity against competing anions and broad pH compatibility. Energy-dispersive X-ray spectroscopy (EDS) elemental mapping and X-ray photoelectron spectroscopy (XPS) analyses confirmed that anion exchange governs the adsorption process. Dynamic flow-through adsorption experiments demonstrated nearly quantitative removal of 0.2 mM MnO₄⁻ at a flow rate of 1 mL min⁻¹, with complete regeneration achieved by washing with HCl solution. Furthermore, both static and dynamic adsorption tests revealed excellent recyclability.

The amphiphilic balance between cationic and hydrophobic segments is a critical determinant of the trade-off between antibacterial activity and biocompatibility of membranolytic polymers. In tertiary amine-based systems, this balance is dynamic and exquisitely sensitive to the pH of the tissue microenvironment. To elucidate the relationship between polymer composition and antibacterial efficacy across a physiological pH range, we developed a library of polymeric proton-gated membranolytic switches (PPGMSs) composed of butyl methacrylate and various tertiary amines. These switches achieve precise, pH-activated antibacterial activity, which is governed by the equilibrium between cationic (protonated amine) and hydrophobic butyl methacrylate and deprotonated amine domains. The switching pH of these switches increases with a higher proportion of tertiary amine or a decrease in higher amine hydrophobicity. From this library, P(E₆₀/B) emerged as a lead compound, demonstrating potent activity against E. coli and P. aeruginosa under acidic conditions, and minimal cytotoxicity toward mammalian cells at neutral pH (7.4). Mechanistic studies confirmed bacterial membrane disruption as the mode of action. Crucially, P(E₆₀/B) exhibited significant efficacy in a murine peritonitis model, reducing bacterial loads in a dose-dependent manner. This work establishes PPGMSs as a versatile platform for designing precision antimicrobials that leverage microenvironmental cues for selective therapy.

阳离子和疏水段之间的两亲性平衡是膜溶性聚合物抗菌活性和生物相容性之间权衡的关键决定因素。在基于叔胺的系统中，这种平衡是动态的，对组织微环境的pH值非常敏感。为了阐明聚合物组成与生理pH范围内抗菌功效之间的关系，我们建立了一个由甲基丙烯酸丁酯和各种叔胺组成的聚合物质子门控膜解开关（ppgms）文库。这些开关实现精确的，ph活化的抗菌活性，这是由阳离子（质子化胺）和疏水性甲基丙烯酸丁酯和去质子化胺域之间的平衡控制。这些开关的开关pH值随着叔胺比例的增加或高胺疏水性的降低而增加。从这个文库中，P（E60/B）作为先导化合物出现，在酸性条件下对大肠杆菌和铜绿假单胞菌具有有效的活性，在中性pH下对哺乳动物细胞的细胞毒性最小（7.4）。机理研究证实细菌膜破坏是其作用方式。关键是，P（E60/B）在小鼠腹膜炎模型中表现出显著的疗效，以剂量依赖的方式减少细菌负荷。这项工作建立了ppgms作为设计精确抗菌剂的通用平台，利用微环境线索进行选择性治疗。

Ultraviolet irradiation and oxidation are the primary factors causing aging in living organisms and organic materials. This study presents a multifunctional chemical group, substituted cyanoacrylate (SCA) group, which exhibits strong ultraviolet absorption capability, excellent antioxidant property. Concurrently, SCA groups undergo C=C bond metathesis reactions under thermal activation, endowing crosslinked networks with reprocess ability. Through synthesis of small-molecule model compound, the UV-absorption and antioxidant characteristics of substituted cyanoacrylate groups were experimentally confirmed. Based on a cascade reaction combining thiol-ene addition and Knoevenagel condensation, we synthesized linear polymers with C=C bonded backbones. This polymer exists as a viscous liquid at ambient temperature (M_n = 3,700 g/mol, T_g = -19°C), functioning as a polymeric UV-absorber/antioxidant. Furthermore, dynamic covalent polymer networks (DCPNs) were prepared using the same reaction with tetrathiol monomers as cross-linkers. This SCA-based DCPN demonstrates high mechanical strength (tensile strength > 17 MPa, elongation at break > 175%), high optical transparency (>90% transmittance for red light), unique UV/oxidation resistance and reprocess ability. These properties establish the material as a sustainable protective coating suitable for demanding applications.

紫外线照射和氧化是导致生物体和有机物老化的主要因素。本研究提出了一种多功能化学基团——取代氰基丙烯酸酯（SCA）基团，它具有较强的紫外吸收能力和优异的抗氧化性能。同时，SCA基团在热活化下进行C=C键复合反应，使交联网络具有再加工能力。通过合成小分子模型化合物，实验证实了取代氰基丙烯酸酯基团的紫外吸收和抗氧化特性。基于巯基加成和Knoevenagel缩合的级联反应，合成了以C=C键为骨架的线性聚合物。该聚合物在常温下（Mn = 3700 g/mol, Tg = -19℃）呈粘性液体存在，具有高分子紫外线吸收剂/抗氧化剂的功能。此外，以四硫醇单体为交联剂，采用相同的反应制备了动态共价聚合物网络（dcpn）。这种基于sca的DCPN具有高机械强度（抗拉强度为17 MPa，断裂伸长率为175%）、高光学透明度（红光透过率为90%）、独特的抗紫外线/抗氧化性和再加工能力。这些特性使该材料成为适合苛刻应用的可持续保护涂层。

To address the critical limitations of conventional photoinitiators, including complex synthesis, poor LED wavelength matching, and high molecular mobility, this study rationally designed and synthesized ten vinyl ketone derivatives functionalized with diverse electron-donating substituents. Five of these structures, HMPO-4, HMPO-5, HMPO-6, HMPO-7, and HMPO-8 were found to possess excellent photo-initiating activity, with the maximum absorption wavelengths red-shifted to the visible region, with a maximum molar extinction coefficient of more than 24,000 M⁻¹cm⁻¹. The multi-component HMPO initiation system effectively initiated PEGDA polymerization under 405 nm and 480 nm LED irradiation, with HMPO-6 exhibiting optimal performance, achieving CC double bond conversions of 96% and 91%, respectively. Steady-state photodegradation and ESR spectroscopy analyses revealed favorable photochemical properties, along with excellent solubility and biocompatibility. Notably, HMPO-6 demonstrated superior migration stability, exhibiting a minimal migration rate of 0.9%. Furthermore, this novel photoinitiator enabled efficient 3D printing under low-intensity (5 mW/cm²) 405 nm LED irradiation.
