光引发自修复聚合物材料研究进展

Progress in Light-Triggered Self-Healing Polymer Materials

综述了近几年来光引发自修复聚合物材料的研究进展。根据自修复机理的不同,光引发自修复方法可分为基于光交联反应的自修复、光置换反应自修复和光致超分子反应自修复。文中重点论述这3种自修复方法中涉及的材料的设计、光引发机制和自修复机理,并对光引发自修复聚合物材料的发展前景进行了展望。

Research progress in light-triggered self-healing polymer materials in recent years was summarized. According to the self-healing mechanisms, light-triggered self-healing methods in polymer materials can be classified into self-healing based on a photo-crosslinking reaction, self-healing based on a photo-triggered metathesis reaction and self-healing based on photo-supramolecular chemistry reaction. The materials design, light-triggered characteristics and self-healing mechanisms related to three kinds self-healing methods were discussed. Future research on light- triggered self-healing polymer materials was prospected.
