摘要:回顾了微胶袁型自修复高分子材料中双环戊二烯- Grubbs催化剂、聚二甲基硅氧烷-锡(铂)催化剂、环氧
树脂-固化剂和异魚酸酯等自修复体系的研究現状,重点介绍了异氰酸酯胶彙型自修复材料的修复机理和研究新
进展。异氰酸酯胶型自修复是通过异氰酸酯修复剂荆(主要是异佛尔酮二异氣酸酯、六亚甲基二异氰酸酯及其
三聚体等)潮固化来实现,并简要探讨了影响微胶自修复高分子材料自修复效果的主要因素(微胶囊的芯材、
力学性能以及微胶囊与基材的相容性)。最后指出了微胶型自修复高分子材料今后的研究方向(建立自修复过
程的模型,将微胶应用到存在一些如晶界、气孔等徽结构的材料中)及其应用前景(提高航空航天和民用高
铁等高速高风险项目的可靠性,开发自修复涂料、胶黏剂等)

Abstract: This paper begins with a review of the research status of microcapsules-based self-healing
polymeric materials including dicyclopentadiene-grubbs catalyst, polydimethylsiloxane-tin ( P
catalyst, epoxy-curing agent and isocyanate system. Self-healing mechanism and research progress of
encapsuled isocyanate self-healing material are summarized. Self-healing function of particles
encapsuled isocyanate actived through the curing process of isocyanate agent(mainly includes
Isophorone diisocyanate, hexamethylene diisocyanate and its trimer ) healing in moisture environment
Following that, the factors(core material, mechanical property of microcapsules and its compatibility
with substrate)influencing self-healing properties of microcapsules-based self-healing polymeric
materials are briefly discussed. Finally, the future research directions, eg. establishment of self-healing
process models and applications of microcapsules to material with microstructure such as grain
boundary, porosity, are pointed out and the application prospects (improving the reliability of some
high-speed high-risk projects such as aerospace and civil high-speed rail, self-healing coatings and
adhesives development)of self-healing materials are exhibited
