摘　　要：介绍了聚合物/热塑性弹性体/纳米无机粒子三元复合材料的形态结构及增韧机理,分析了热塑性弹性体、纳米无机粒子、加工工艺、界面性能4个方面对聚合物/热塑性弹性体/纳米无机粒子三元复合材料形态和性能的影响。热塑性弹性体和纳米无机粒子对聚合物有协同增韧增强作用,加料顺序是形态结构的最主要影响因素,聚合物的力学性能非常依赖热塑性弹性体和纳米无机粒子在聚合物中的存在形态。最后,展望了该体系未来的研究方向。The morphological structures and toughening mechanism of the polymer/thermoplastic elastomer/ inorganic nanoparticles ternary composites are described. The effects of thermoplastic elastomer, inorganic nanoparti- cles, processing technology and interfacial properties on toughening and strengthening performances of these ternary composites are also analysed. It is found that thermoplastic elastomer and inorganic nanoparticles has a synergistic effect on toughening and strengthening performances. The final morphological structure is mainly controlled by the blending sequence. The mechanical properties of the composites greatly rely on the morphology. The future research directions are expected.
