摘要: 利用L-S相转化法将聚醚型聚氨酯（PEU）和聚醚砜（PES）共混,以聚乙二醇（PEG）为添加剂,制备PEU/PES共混膜,并通过测定比较共混膜的结构与性能.结果表明：聚合物浓度、共混组成比、添加剂种类与浓度是影响PEU/PES共混膜性能的主要因素.Abstract: Polyether-polyurethane (PEU) and polyethersulfone (PES) were blended for preparing PEU/PES blend membranes by using L-S phase-inversion method in the presence of polyethylene glycol as a additive. By determing and comparing structures and properties of di
