摘　　要：环氧树脂作为主要的热固性树脂之一,性能优异,应用广泛。但由于其固化交联密度高,脆性大的缺点,环氧树脂的实际应用受到了极大地限制。因此,环氧树脂的增韧改性成为了人们研究的重点。本文主要从橡胶、聚硅氧烷、热塑性塑料、树枝状聚合物、嵌段聚合物、纳米填料这几种主要增韧材料出发,系统综述了近几年来环氧树脂增韧改性的研究进展,简要阐述了各种材料的增韧机制,并对环氧树脂增韧改性的研究进行了分析与展望。Epoxy resins constitute an important class of thermosets which are used extensively with excellent properties. However, the inherent brittleness as a result of high crosslinking density has greatly limited their applications in certain areas. Therefore, the toughening modification of epoxy resins has become the focus of research. In this review, recent advances on toughening epoxy resins based on some major toughening materials such as rubbers, silicones, thermoplastics, dendrimers,block polymers,and nanofillers have been summarized systematically. In addition, the toughening mechanism of various materials have been briefly described, and meanwhile, the research on toughening modification of epoxy resin has been analyzed and prospected.
