摘要： 采用原位聚合法在聚丙烯微孔膜基材内复合聚丙烯酸丁酯(PnBA)制备了一种新型聚合物互穿网络PP/PnBA.用傅立叶扫描红外光谱、偏光显微镜、扫描电镜、X射线光电子能谱、广角X射线衍射及力学拉伸等手段进行了表征。发现复合膜表面PnBA的多少依赖于聚丙烯微孔膜基材表面微孔的量及分布情况,复合膜基本上保持了聚丙烯微孔膜基材的骨架结构,交联聚丙烯酸丁酯填入了几乎全部微孔,成为一个与聚丙烯相互穿的新的连续相,形成了真正互穿网络。复合膜的力学延展性有一定程度的改进。

Abstract: Anovel interpenetrating polymer network(IPN)of isotactic polypropylene/poly n-butyl acrylate(PP/PnBA)was prepared by in-situ polymerization of n-butyl acrylate in the pores of matrix polypropylene(PP)microporous membrane.The composite IPNmembrane was characterized by using the methods of FT-IR, polarized light microscope(PLM), SEM, XPS, WASDand stress-strain measurements。It has been found that the PnBAcomposition in the surface of the composite membrane was depedent on the pore number in the surface of the matrix PPmembrane.The structure of the matrix PPmicroporous membrane was preserved in a great extent.Almost all the pores were filled with crosslinked PnBAso that a continuous PnBAphase formed which was interpenetrated with PPphase。The mechanical properties of composite IPNmembrane were improved in some aspects in comparison with the matrix membrane.
