摘　　要：将质量分数20%半水硫酸钙晶须(HCSW)与等规聚丙烯(iPP)熔融挤出后制备了HCSW/iPP复合材料,研究了HCSW/iPP复合材料性能以及HCSW对iPP诱导β晶的机理。结果表明:HCSW对iPPβ晶有良好的成核效果;与iPP相比,HCSW/iPP复合材料的力学性能有不同程度提高;利用“晶格匹配理论”计算得出HCSW与iPP有较好的附生效果。Hemihydrate calcium sulfate whisker(HCSW)with mass fraction 20%and isotactic polypropylene(i PP)composites were prepared by melt extrusion.The properties of HCSW/i PP composites and the mechanism of HCSW on i PP-inducedβcrystals were studied.The results show that HCSW has a good nucleation effect on i PPβcrystals.Compared with i PP,the mechanical properties of HCSW/i PP composites have been improved to varying degrees.Based on“lattice matching theory”,it is calculated that HCSW and i PP have better epiphytic effect.
