本征型自修复弹性体的研究进展

Research Progress of Intrinsic Self-healing Elastomers

近年来自修复材料受到越来越多的关注,根据修复机制,自修复材料可分为外援型和本征型,本征型自修复材料具有更重要的实用价值与研究意义。本文综述近年来基于非共价键体系、可逆共价键体系和多重动态键复合体系的本征型自修复弹性体的最新研究进展,总结目前自修复弹性体研究所面临的问题,并指出自修复弹性体的研究方向,提出除了研究自修复弹性体的合成和性能表征以外,还应在分子尺度上揭示自修复弹性体破坏和修复的物理机制。

In recent years,self-healing materials attracted more and more attention.According to the repair mechanism,self-healing materials could be divided into foreign aid type and intrinsic type.Intrinsic self-healing materials had more important practical value and research significance.In this paper,the latest research progress of intrinsic self-healing elastomers based on non-covalent bond system,reversible covalent bond system and multiple dynamic bond composite system in recent years were reviewed,the problems faced by the research of self-healing elastomers were summarized,and the research direction of self-healing elastomers were pointed out.An opinion was put forward that in addition to the research on the synthesis and performance characterization of self-healing elastomers,the physical mechanism of self repairing elastomer damage and repair should also be revealed at the molecular scale.
