In this article, results of PET track-etched membranes (PET TeMs) hydrophobized by photo-induced graft polymerization of stearyl methacrylate (SM) inside the pores were presented. The effects of monomer concentration, time of irradiation and the nature of the solvent on the degree of grafting and membrane morphology were investigated. The PET TeMs with pore diameters ranging from 350 nm (pore density of 1 × 10 pore/cm) to 3.05 µm (pore density of 1 × 10 pore/cm) were hydrophobized and tested for oil-water separation by using hexadecane-water and chloroform-water emulsions. Studies have shown high separation performance for membranes (up to 1100 mL/m·s) with large pore diameters while achieving a high degree of purification.
本文介绍了通过在孔内光诱导甲基丙烯酸硬脂酯（SM）接枝聚合而疏水化的聚对苯二甲酸乙二酯径迹蚀刻膜（PET TeMs）的结果。研究了单体浓度、辐照时间和溶剂性质对接枝度和膜形态的影响。对孔径范围为350纳米（孔密度为1×10个孔/平方厘米）至3.05微米（孔密度为1×10个孔/平方厘米）的PET TeMs进行疏水化处理，并使用十六烷-水和氯仿-水乳液对其进行油水分离测试。研究表明，大孔径膜具有较高的分离性能（高达1100毫升/平方米·秒），同时能实现高度纯化。
