摘　　要：作为一种高分子智能材料,自愈合凝胶在解决软材料损伤修复以及凝胶-生物体组织之间的界面接口问题,实现软材料智能化、高效化和环境友好化具有重要意义.近年来利用动态建构化学的基本原理,通过动态非共价键、可逆动态共价键相互作用,设计了一系列具有良好自愈合性能的新型凝胶材料.本文以物理型和化学型动态自愈合凝胶为例,综述了自愈合凝胶的分子设计思路、性能,并分析了影响自愈合性能因素,并对其未来的发展进行了展望.As a smart polymer material, self-healing gel not only can repair the cracks of soft matter, but also potentially solve the problem of interface connection between gels and biological tissues. Therefore, self-healing gel has a critical importance in achieving intelligence, high efficiency and environment-friendly of soft matters. In recent years, on the principle of constitutional dynamic chemistry, a series of new type gels with excellent self-healing performance have been designed by using non-covalent bond and dynamic covalent interaction. In this review, the strategies of molecular design and performance of the self-healing are introduced on the base of analyzing some physical and chemical dynamic self-healing gels. Furthermore, the factors affecting the performance of the self-healing gel are discussed, as well as the challenge, problem and future development of self-healing gel are proposed.
