| 摘 要： | 以嵌段共聚物ＩＳＩ和ＩＭｓ的共混物为原料，ＰＰ微孔膜为基膜制成了复合膜，再经过交联、季胺化和磺化而制成了一种新的共混型镶嵌荷电膜。进一步的研究显示，该膜具有典型的镶嵌荷电膜结构及性能特点，与ＭｓＩＳＩＭｓ五嵌段荷电膜具有相似的膜形态与膜结构；电性能也十分相近，膜面电阻分别为３５０、９７０Ω·ｃｍ＾２，电压渗系数分别为８×１０＾－９、６．１×１０＾－９Ｖ／Ｐａ。表明可以用ＩＳＩ／ＩＭｓ共混物代替五嵌

| Abstract: | A new charge-mosaic composite membrane composed of cation and anion permeable domains was prepared.Poly(isoprene-4-methylstyrene) diblock copolymer and poly(isoprene-styrene-isoprene) triblock copolymer,which were used as the precursor of the charge-mosaic membrane,were dissolved in benzene,and then casted on a polypropylene microporous supporting membrane.After chemical modification the ISI/IMs charge-mosaic composite membrane was obtained.The experimental results show that the ISI/IMs charge-mosaic composite membrane is similar in membrane structure and property to the MsISIMs charge-mosaic composite membrane. |
