| 摘 要： | 自修复是指材料在受到损伤后可自行修复,并在一定程度上恢复其力学性能的特性,对提高材料的使用寿命及安全性具有重要意义。离聚物中的离子基团在一定条件下由于静电相互作用及与主链的不相容性而相互聚集,形成动态可逆的物理交联点,从而赋予了离聚物材料在无外加修复剂的条件下即可实现自修复的特性。本文系统评述了离聚物型高分子材料的自修复过程与机理、常用的离聚物体系、激发离聚物自修复行为的方式及影响离聚物自修复特性的因素。

| Abstract: | Self-healing, defined as the ability of materials to self-repair and recover their mechanical properties when being damaged, is quite significant for materials in extending their service time and improving their usage safety. The ionic pairs in ionomers tend to aggregate due to electrostatic interaction and incompatibility with the main chain, forming dynamic physical crosslinks, thus endowing inonomers with the ability to self-heal without the aid of extrinsic healing agents. Herein, the self-healing progress and mechanisms, currently investigated self-healing ionomers, methods of triggering their self-healing behaviors as well as factors that may influence their self-healing ability are systematically reviewed. |
