Combining high heat resistance and green sustainability is a great challenge in developing shape memory epoxy resins. Herein, starting from synthesizing fully biobased trifunctional compound (ER), kind of resin system (EFTx, where x the molar ratio carboxyl to groups) developed. The effects on structure properties EFTx resins were systematically investigated. Results show that cured have excellent resistance, mechanical properties, performance, recycle ability. As increases, glass transition temperature (Tg) initial thermal decomposition (Tdi) decrease while both self-healing efficiency remolding increase. Tg storage modulus each are much higher than those reported Among resins, EFT1.0 shows best-integrated performance; specifically, its Tg, Tdi, tensile strength, as 156 °C, 293 40.99 MPa, 90.5%, respectively, meanwhile it also has outstanding property reflected by fixation (Rf = 100%) recovery (Rr 97.8%) under bend-recovery experiments well Rf (93.2%) Rr (66.1%) after four cycles. integrated performance attributed their unique structures combine rigid stilbene structure, furan ring, abundant ester bonds.

Due to their remarkable features of lightweight, high strength, stiffness, high-temperature resistance, and corrosion carbon fiber reinforced polymers (CFRPs) are extensively used in sports equipment, vehicles, aircraft, windmill blades, other sectors. The urging need develop a resource-saving environmentally responsible society requires the recycling CFRPs. Traditional CFRPs, on hand, difficult recycle due permanent covalent crosslinking polymer matrices. combination adaptable networks (CANs) with fibers (CFs) marks new development path for closed-loop recyclable CFRPs resins. In this review, we summarize most recent developments from unique paradigm dynamic polymers, CANs. These sophisticated materials diverse functions, oriented towards CFs resin sustainability, further categorized into several active domains bonds, including ester imine disulfide boronic acetal linkages, etc. Finally, possible strategies future design CFPRs by combining chemistry innovation interface science proposed.

The recycling of waste rubber (WR) is beneficial to the sustainable development industries. However, interactions among WR are weak, limiting WR. In this work, our group designed bis-diazo compounds promote for through aliphatic C–H insertion strategies. Specifically, upon hot pressing, produce bis-carbenes which react with on surface by insertions, and then we obtain recycled materials. As a result, stress–strain curves show that strength increases steadily increase compound loading, has reached level butadiene styrene rubbers. Moreover, introduced disulfide bonds endow reprocessability. Stress–relaxation experiments at different temperatures have unique vitrimer viscoelastic properties. feasibility enhance insertions opens opportunities recycle reinvent industrial
