摘　　要：弹性体材料因其独特的弹性和耐久性,在航空航天、汽车制造等领域中有着至关重要的作用。然而,弹性体材料在废弃后难以回收利用,造成了巨大的资源浪费和环境污染。动态共价化学通过其动态可逆性键赋予材料在不同环境下保持机械强度、自我修复、再加工和回收利用的能力,从而在材料合成和性能调控上具有独特优势,能够在减轻环境压力的同时带来更高的经济效益。本文综述了动态共价键在弹性体材料降解回收中的研究现状,分析了不同动态键的断裂机理和降解性能,揭示了这些新型材料的特性和应用潜力。未来,基于动态共价化学的弹性体材料有望在环境保护和资源循环利用中发挥更大作用。Elastomers play a crucial role in many fields such as aerospace and automotive manufacturing due to their unique elasticity and durability.However,it is difficult to recycle and reuse after being discarded,resulting in significant resource waste and environmental pollution.Dynamic covalent chemistry based on reversible dynamic covalent bonds is characterized by reversible dissociation and reassociation abilities.Covalent adaptive network derived from dynamic covalent chemistry is regarded as a revolutionary polymer network.This network endows polymers with self-healing,reprocessing and recycling capabilities in different environments,achieving unique advantages in polymer synthesis and performance regulation.Therefore,dynamic covalent crosslinked elastomers can not only exhibit excellent performance during use,but also undergo degradation and recycling under specific conditions after use.In comparison with hot pressing recycling,degradation recycling can achieve monomer recovery and reuse while reducing environmental effects,bringing higher economic benefits The current research advance of degradation and recycling of elastomers based on dynamic covalent bonds is reviewed.By exploring the degradation mechanism and performance of different types of dynamic bonds,the characteristics and potential applications of these new elastomers are discussed in detail.Elastic materials based on dynamic covalent chemistry are expected to play a greater role in environmental protection and resource recycling in the future.
