【摘要】：评述近年国内外数种外援型微胶囊自修复复合材料体系的研究成果,包括双环戊二烯-Grubbs体系、聚二甲基硅氧烷体系、活性溶剂体系、环氧树脂体系和异氰酸酯体系等,比较这些体系微胶囊的设计方法、主要性能和应用范围等.设计外援型微胶囊自修复复合材料,通过胶囊破裂流出囊芯可有效封闭裂纹,达到延长材料服役寿命的效果.指出材料断裂机理与微裂纹的产生及扩展密切相关,断裂行为决定高聚物材料中设计化学体系进行智能修复的过程.开辟了自修复聚合物材料科学研究新方法和工程应用的新途径.展望了微胶囊自修复材料的科研和工程应用前景.
[Abstract]:In recent years, several kinds of foreign microcapsule self-repairing composite systems were reviewed, including dicyclopentadiene Grubbs system, polydimethylsiloxane system, active solvent system, epoxy resin system and isocyanate system, etc. The design methods, main properties and application scope of these microcapsules were compared. The external microcapsule self-repairing composite material is designed. The crack can be effectively sealed by the capsule rupture and outflow core, and the service life of the material can be prolonged. It is pointed out that the fracture mechanism is closely related to the generation and propagation of microcracks, and the fracture behavior determines the process of intelligent repair of design chemical systems in polymer materials. It opens up a new way of scientific research and engineering application of self-repairing polymer materials. The prospect of scientific research and engineering application of microencapsulated self-repairing materials is prospected.
