摘要
综述了不同自愈体系的自愈机制,根据是否需要外加修复剂,将自愈体系分为本征型和外援型两类,其中本征型自愈体系的愈合机制是指非共价键(氢键作用、疏水作用、静电作用)和共价键(DA键、双硫键)的重新结合作用;外援型自愈体系是引入修复剂,利用修复剂修复损伤。最后,对自愈体系的主要的应用技术:层层自组装技术、微胶囊封装技术和化学转化膜技术进行了综述。
The re-healing mechanism of different re-healing coating systems is reviewed. According to whether a restorative agent is added or not, the re-healing coating systems may be divided into extrinsic re-healing coating system and intrinsic one. The intrinsic re-healing coating system mainly refers to the rebinding effect of non-covalent bonding, such as hydrogen bonding, hydrophobic effect and electrostatic interactions and covalent bonding, such as DA bonding and disulfide bonding. The extrinsic re-healing coating system relies on the incorporation of restorative agents, with the function of which the damage of a coating system may be restored. The main application technologies of re-healing coating system, such as layer-by-layer(LbL) self-assembly technology, microcapsule packaging technology and chemical conversion coating technology, are reviewed.
