摘　　要：少量纳米粒子可同时实现对聚丙烯(PP)基体的增强增韧并对其力学性能、结晶性能、抗老化及抗菌等性能均会产生一定的影响。用无机纳米粒子改性PP可制备综合性能优异的聚丙烯/无机纳米复合材料,是目前复合材料领域研究的热点。综述了无机纳米粒子改性聚丙烯的最新研究进展,在介绍PP纳米复合材料体系和制备方法的基础上重点对PP纳米复合材料的微观结构、力学性能,结晶和抗老化等性能进行了综述。研究表明少量纳米粒子可大幅度提升基体材料的综合性能,但目前许多文献报道的表面改性和制备技术仍没有解决纳米团聚的难题,特别是要实现工业生产则纳米粒子在PP基体中的分散性尚需进一步改善。Small amount ofnanoparticles can reinforce and toughen polypropylene （PP） and have much effect on the machanical properties, crystallization behavior, anti-aging and antibacterial properties of PP matrix. High performances and multifunctional PP/inorganic nanocomposites can be prepared by modification of PP with nanoparticles, which is a new generation composite and has attached great interests. The newest developments, preparations, machanical properties, morphology, crystallization and anti-aging properties of PP/inorganic nanocomposites are summarized and discussed in this paper. Research results indicate that low loading of inorganic nanoparticles may lead to tremendous increase of comprehensive properties, but the surface-modification and preparation methods reported in many articles do not resolve the aggregation of nanoparticles. The dispersion of nanoparticles in PP matrix needs to be improved especially in the implementation of industry.
