综述了环氧树脂(EP)的特性、发展、增韧方法以及近4年来对EP增韧改性的热点研究[包括橡胶弹性体增韧改性、热塑性树脂增韧改性、互穿聚合物网络(IPNs)增韧改性、热致性液晶聚合物(TLCP)增韧改性、刚性纳米粒子增韧改性、超支化聚合物(HBP)增韧改性、核/壳结构聚合物增韧改性、柔性链段固化剂增韧改性和无机晶须增韧改性等],并对比分析了不同增韧改性方法的优势和劣势;最后展望了未来“十二五”期间增韧改性EP的研究方向。
The properties, development and toughening of epoxy resin (EP), as well as the hot research on the toughening and modification of EP in recent 4 years [including rubber toughening modification, toughening modification of thermoplastic resin, interpenetrating polymer Toughening modification of IPNs, toughening modification of thermotropic liquid crystal polymer (TLCP), toughening modification of rigid nano-particles, toughening modification of hyperbranched polymer (HBP), addition of polymer of core / shell structure Toughening modification, toughening modification of flexible chain segment curing agent and toughening modification of inorganic whiskers, etc.]. The advantages and disadvantages of different toughening methods were compared and analyzed. Finally, the future “Twelfth Five-Year Plan” During the toughening modified EP research direction.
