摘要

以聚醚砜(PES)为原料，均苯三甲酸(TMA)为添加剂，采用浸没沉淀相转化法制备聚醚砜超滤基膜，之后将聚乙烯醇(PVA)溶液涂覆在膜表面，经加热交联得到低截留分子量超滤膜。实验结果表明，随着聚乙烯醇浓度升高，截留分子量先减小再增加；随着热处理温度的升高，水通量减少，截留分子量减小。聚乙烯醇质量浓度为0.1%，80℃加热10 min，膜的截留分子量为900，纯水通量为6.10 L/(m

·h)。红外光谱分析证实PVA与TMA反应生成了交联结构。

Abstract

The PES ultrafiltration base membranes were prepared with PES

DMAc and TMA through the method of immersion precipitation phase inversion. Then PVA solution was coated on the base membranes surface and crosslinked by heating to obtain low m

olecular weight cut-off ultrafiltration membranes. The experimental results showed that with the increase of PVA concentration

the molecular weight cut-off first decreased and then increased; as the heat treatment temperature increased

the water flux decreased and the molecular weight cut-off decreased. When the PVA mass fraction is 0.1% and heat-treated at 80°C for 10 min

the molecular weight cut-off of the membrane was 900. The pure water flux was 6.10 L/(m

·h) . The cross-linking structure of PVA and TMA was confirmed by infrared spectroscopy analyzer.
