摘　　要：提出了对环氧树脂增韧改性的必要性,综述了近年来国内外学者对橡胶弹性体增韧、热致性液晶高分子增韧、热塑性塑料增韧、核壳聚合物增韧、超支化聚合物增韧改性环氧树脂的研究进展,并论述了这几种增韧剂的增韧机理及其增韧环氧树脂的优缺点。最后对几种环氧树脂增韧改性方法进行了对比,指出在增韧的同时降低对材料其他性能的负面影响、降低成本、协同增韧是未来的发展方向。The necessity of toughening and modifying epoxy resin was put forward.The domestic and foreign scholars'research progress of epoxy resins toughening modified by rubber,thermotropic liquid crystal polymers,thermoplastics,core-shell polymers,and hyperbranched polymer in recent years was summarized.The toughening mechanism,advantages and disadvantages of these toughening agents were discussed.Finally the toughening modification of epoxy resin by these toughening agents was compared.It was pointed out that the future development direction was to reduce the negative impact on other properties of materials while toughening,reduce the cost and collaborative toughen.
