摘　　要：核-壳粒子增韧结合了弹性体增韧和刚性粒子增强的优点,将其用于聚合物共混体系中有可能得到比基体树脂更高韧性更好刚性的复合材料。本文综述了相关核-壳粒子的分类、形态、形成机制,以及它们对聚合物基体的增韧机理,并详细阐述了反应性和非反应性聚合物共混体系中原位形成的核-壳粒子形态演化规律及其对共混物力学性能的影响。Polymeric materials modified by core-shell particles combine the advantages of elastomer toughening and rigid-particles reinforcing effects, and thereby it is possible to obtain composite materials with both high toughness and high rigidity simultaneously. In this review, the classification, morphologies, formation mechanism of core-shell particles, and toughening mechanism on polymer matrix are presented. Additionally, the morphological evolution and its effects on mechanical properties of both reactive and non-reactive blends are discussed in details.
