摘要

研究了半晶形态对共规聚丙烯(sPP)基材料电击穿强度的影响。研究了不同的sPP样品(具有不同的分子质量和共异性)和sPP/乙烯无规共聚物。利用WAXD、DSC和SEM等技术对材料的半晶形貌进行了表征。通过不同的加工条件和与乙烯的共聚，所考虑的材料的结晶形态发生了变化。然后，材料的结晶度和晶间相含量与电强度相关。

Influence of semi-crystalline morphology on the electrical breakdown properties of sPP based materials

The influence of semi-crystalline morphology on the electrical breakdown strength of syndiotactic polypropylene (sPP) based materials is investigated. Different sPP samples (with varying molecular mass and syndiotacticity) and an sPP/ethylene random copolymer are studied. The semi-crystalline morphology of these materials was characterized using different techniques like WAXD, DSC and SEM. The crystalline morphology of the considered materials was varied by varying the processing conditions and by copolymerizing with ethylene. The crystallinity and the crystalline interphase content of the materials were then correlated with the electrical strength.
