Polymer Chemisty邀请综述:生物基环氧共价适应性网络研究进展

标题:Progress in design and synthesis of biobased epoxy covalent adaptable networks

摘要:Epoxy thermosets have outstanding physical and chemical properties, but they are unrecyclable/nondegradable due to their permanently crosslinked networks and are also overly dependent on fossil resources. This leads to serious environmental problems and resource depletion, which limit the sustainability of epoxy thermosets. Biobased epoxy covalent adaptable networks (CANs) are emerging polymers crosslinked with dynamic covalent bonds (DCBs) and derived from renewable biomass resources. Based on the exchange reactions of DCBs, they are recyclable and degradable, with other attractive functionalities such as self-healing, weldability, and reconfigurability. Therefore, biobased epoxy CANs provide a new method for the sustainable development of epoxy thermosets. This review summarizes recent advances in biobased epoxy CANs research. The design, synthesis, and properties of biobased epoxy CANs are discussed, and opportunities and challenges for their future development are also suggested.
