摘要
以聚丙烯微孔膜为基材，通过扩散控制原位共聚合的方法在膜内填充了组成沿膜的厚度方向逐渐改变的无规共聚物，Ｘ－－光电子能谱（ＸＰＳ）、全反射红外光谱（ＡＴＲ）以及动态粘弹谱的分析结果，说明所制备得到的复合膜具有明显的渐变聚合物性质。
andom copolymers were compounded into pores of microporous polypropylene membrane by diffusion control in-situ copolymerization.By the analysis of X-ray photoelectron spectroscopy(XPS)and attenuated reflection infra-red spectroscopy(ATR).It has been proofed that the composition of copolymers varied along the thickness direction of the result composite membrane.Dynamic mechanical analysis show that the composite membrane possessed properties of gradient polymer.
