摘要
采用DSC、WAXD及偏光显微镜(PLM)对纳米CaCO_3改性PP的等温结晶、等速降温结晶过程及熔融行为进行了研究。结果表明:纳米CaCO_3对聚丙烯的结晶成核有诱导作用,增加了β晶含量,提高了聚丙烯的冲击韧性。
Crystallization of nano - CaCO3 modified PP composite were researched by means of DSC, WAXD and PLM. It was found that nano- CaCO3 could induce PP nucleation and increase β- crystalline form , thus improving impact strength of PP/ nano - CaCO3 composite.
