ɑ-纤维素/聚砜共混超滤膜制备及抗污染性能研究

, 2015
α-纤维素分子中含有大量羟基，利用ɑ-纤维素对聚砜超滤膜进行共混改性有望提高聚砜膜的亲水性。以聚砜为原材料，向铸膜液中添加ɑ-纤维素，采用浸没沉淀法制备了新型ɑ-纤维素/聚砜共混超滤膜，并通过红外（FTIR）、热重、扫描电镜（SEM）、孔隙率、接触角、通量及抗污染测试等手段对膜性能进行表征 ...

一种大通量两性纳滤膜的制备方法

, 2013
本发明涉及一种大通量两性纳滤膜的制备方法。传统纳滤膜的制备方法主要分为相转化法和复合法，但很难得到通量很大的膜。该方法是超滤膜用乙醇和去离子水洗涤，然后浸泡于烯烃类阳离子单体溶液中，100～600W紫外灯下辐照3～120分钟，得到阳离子纳滤膜；阳离子纳滤膜用去离子水洗涤，然后浸泡于两性烯烃类单体溶液中，100～600W紫外灯下辐照2～40min,得到两性纳滤膜；最后两性纳滤膜用去离子水洗涤。本发明方法制备的两性纳滤膜在0.5MPa下水通量为55～200L/m2h，对氯化钠、MgCl2 ...
