高分子分离膜材料的改性方法

The modification methods of polymer membrane materials

    摘要
  • 摘要: 本文着重综述了目前常用的高分子分离膜材料的改性方法.表面活性剂改性法可以改善膜表面的亲水性,提高了膜的通量;溶剂化改性是在一定时间,一定温度下用某种溶剂对聚合物膜进行预处理,以提高膜的分离性能;共混改性不仅简单易行,而且可以利用共混物原组分各自的优点而避开它们的缺点,以扬长避短.等离子体改性是近年发展很快的方法,它操作简单、安全、不造成环境污染.辐射接枝的方法是膜表面改性的重要途径之一,改性后膜的抗污性及其表面的亲水性增强.
