摘要
通过界面聚合的方法制备了以聚甲基丙烯酸二甲氨基乙酯(PDMAEMA)为交联预聚体,以微孔聚砜膜为基膜的复合纳滤膜;研究了凝胶表层的聚电解质特性。实验表明:荷电纳滤膜的表面具有一定的疏水性。交联凝胶层的溶胀度表现出pH、外加盐浓度、温度的响应性。
A composite nanofiltration membrane is fabricated by the interracial polymerization supported on a microporous polysulfone substrate,using PDMAEMA as the prepolymer of the crosslinking reaction. The polyelectrolytes properties of the crosslinked PDMAEMA hydrogel layer are investigated. The results show that the surface of the charged nanofiltration membrane exhibites hydrophobicity. The swelling ratios of the crosslinked hydrogel layers show pH,added salt concentration andtemperate responsibilities.
