环氧树脂增韧改性研究进展

摘要

综述了利用橡胶粒子、热塑性树脂、热致性液晶聚合物(TLCP)、无机纳米粒子、核-壳结构聚合物和超支化聚合物等增韧环氧树脂(EP)的几种方法以及相关的增韧机理,并指出了EP增韧改性中存在的问题,对EP增韧改性的前景进行了展望.%Several methods for toughening epoxy resins by using rubber particles,thermoplastic resins,thermotropic liquid crystalline polymers,inorganic nanoparticles,core-shell polymer and hyper-branched polymers,and toughening mechanism were reviewed.The existing problems were pointed out and the prospects of toughening modification of EP were forecast.
