超支化聚合物在环氧改性中的应用
|
摘要
超支化聚合物(HBPs)因其独特的结构和性质,常被用作环氧树脂(EP)的新型改性剂。文中介绍了HBP修饰的纤维、碳纤维、纳米粒子在EP改性中的应用;比较了不同端基、不同结构的HBPs对改性EP的影响;总结了超支化环氧树脂(HEPs)的合成及其改性EP的进展;展望了生物原料合成的HBPs在改性EP方面的应用前景。
Recently, hyperbranched polymers(HBPs) were found use as the novel modifiers of epoxy resins(EP) because of their unique architectures with tailored properties. This article briefly reviewed the development and applications of HBPs in the reinforcement of EP in recent 5 years. This paper introduced the application of HBP modified nano-particles, fibers, carbon fibers and inorganic substances in EP modification. The effects of HBPs with different end groups and structures on EP modification were compared. The progress of synthesis and EP modification of hyperbranched epoxy resin(HEPs) was summarized. The application prospect of HBPs based on bio-based sustainable feedstock in EP modification was prospected.
