摘　　要：β-聚丙烯基(β-PP)复合材料的高性能化是当前PP改性的研究热点。综述了近年来β-PP/无机粒子复合材料的发展概况,围绕无机粒子刚性和β-晶韧性难以协同的关键问题,总结了现阶段的研究进展:1)通过负载β-成核剂或者无机粒子表面功能化,提高β-PP/无机粒子复合体系的β-晶含量; 2)控制温度、剪切力等工艺条件,调控β-PP/无机粒子复合体系的结晶形态。虽然β-PP复合材料的高性能化研究已经取得显著成果,但在工业化生产和推广应用过程中还存在很多技术问题需要解决。Nowadays, high performance research of beta-polypropylene （β-PP） composites has become a hot topic of PP modification. In this paper, the development of β-PP/inorganic particle composites in recent years was reviewed. The key problem of hardly achieving balance between the stiffness of inorganic particles and the toughness of β-phase was pointed out, and the research progress was summarized as follows ： （ 1 ） to increase the β-phase content through supporting β-nucleating agent on the surface of inorganic particles or surface functionalization; （2） to regulate the crystalline morphology of PP by means of controlling processing conditions such as temperature and shear. Although the high performance study of β-PP composites made remarkable achievements, there are still many problems in production of industry and promotion of application process need to be solved.
