介绍了近年来国内外几种环氧树脂增韧技术(柔性聚合物增韧、超支化聚合物增韧、核壳结构聚合物增韧、互穿网络聚合物增韧、纳米粒子增韧、热致液晶聚合物增韧)的研究动态。 在提高环氧树脂韧性的同时,又不会降低树脂体系的模量和玻璃化转变温度。

Research progress of epoxy resin toughening technologies domestic and abroad was reviewed. The modification methods were toughened by flexible polymer, hyperbranched polymer, core-shell structure polymer, interpenetrating network polymer, nanoparticles, and thermotropic liquid crystal polymer. The toughness of epoxy resin systems was improved without sacrificing its modulus and glass transition temperature.
