摘要: 研究了界面张力对PP/EVA共混体系梯度相形态形成的影响。首先将EVAc进行皂化反应得到一系列-OH基含量不同即极性不同的EVA,然后将这些EVA分别与PP共混从而得到一系列相界面张力不同的共混物。说明通过对共混物相界面张力的调整,可以达到随意控制梯度相形态形成速度的目的。Abstract: Previous researches showed that polypropylene(PP) and ethylene vinyl ace-tate(EVAc) blends could take the form of gradient morphology in the vertical section by annealing. In this research, in order to study the effect of interfacial tension on the format
