摘　　要：自修复聚合物材料是一种具有自修复能力的聚合物智能材料,近年来已成为国内外的研究热点。在聚合物基体中引入可逆共价键,在外界条件刺激下,聚合物可快速、高效自修复,这有助于延长聚合物材料的使用寿命。能形成可逆共价键的反应主要包括可逆开环加成反应、交换反应和稳定自由基重组反应等。文中以不同类型的可逆反应为线索,从可逆共价键的类型、修复条件、修复效率等方面综述了近年来基于可逆共价键的自修复聚合物材料的研究进展,比较了不同可逆共价键形成聚合物的优缺点,并展望了其未来的发展方向。Self-healing polymers are smart materials with self-healing ability, which attracted lots of attentions and have been extensively studied recently. Polymers with reversible covalent bond can be healed faster and more efficiently, which can lengthen their service life. Reversible covalent bonds can be formed by reversible cycloaddition reactions, exchange reactions and stable free radical mediated reshuffling reactions. This review attempted to introduce the progress in self-healing polymers based on different reversible reactions and discuss the future development direction. Meanwhile, the advantages and disadvantages of self-healing polymers prepared by different reversible covalent bond were compared from aspects of healing condition and healing efficiency.
