摘要:: 传统聚合物材料在给人类社会创造便利的同时，也引起了严重的资源浪费和环境污染问题。大力发展可修复、可循环利用及可降解的聚合物材料，能够有效缓解资源浪费及环境污染问题，对构建可持续发展社会具有重要意义。系统总结了基于非共价相互作用及动态共价键的可逆交联聚合物体系制备可修复、可循环利用及可降解聚合物材料方面的进展。基于作者研究组的工作，着重阐述了如何利用多重可逆作用力及微结构的协同制备具有高强度、高韧性及优异抗撕裂性能的可修复与可循环利用聚合物材料，以及具有良好环境稳定性的、可降解的超分子塑料。设计制备基于非共价相互作用与动态共价键的可逆交联聚合物体系，是发展可修复、可循环利用及可降解的聚合物材料的有效思路。

Abstract:: Traditional polymeric materials have pushed the progress of human society by providing numerous light-weight and mechanically robust polymer products. However, these materials also have caused serious resource waste and environmental pollution. Replacing traditional polymeric materials with healable, recyclable and degradable polymeric materials can effectively solve the problems of resource waste and environmental pollution, which is of great significance to the construction of sustainable society. In this review, we systematically summarized the recent development of noncovalently cross-linked polymeric materials capable of healing, recycling and degrading. We demonstrated that the synergy of multiple reversible interactions and micro-/nanostructures provides an effective way to the fabrication of healable and recyclable polymer materials with high mechanical strength, high toughness and excellent damage tolerance as well as degradable supramolecular plastics with good environmental stability. Cross-linking polymer chains with non-covalent interactions and dynamic covalent bonds is practically useful for the fabrication of healable, recyclable and degradable polymeric materials.
