摘要
对聚偏氟乙烯分离膜的亲水化改性方法进行了综述,分析了物理改性、化学改性、等离子体改性以及辐照接枝改性等方法的特点及改性效果,并指出化学改性是从根本上实现了聚偏氟乙烯膜的亲水化改性。
In order to extend the application ranges,a variety of modification techniques have been developed to make the membrane surface hydrophilic.To make a summary,these methods are reviewed,such as physical treatment,chemical treatment,plasma and radiochemical grafting,including their characteristics and effects.Chemical treatment is the ultimate way to achieve the aim for PVDF hydrophilic modification.
