摘要
从膜基体和膜表面两个角度出发,综述了当前对聚偏氟乙烯(PVDF)强疏水性膜的亲水化改性方法,介绍了共混改性、表面化学改性、辐照接枝等方法的机理、优缺点和近年的研究进展,指出了共混改性是今后亲水改性的主要方向。
The research in the hydrophilic modification of poly （vinylidene fluoride） （PVDF） membranes were reviewed. The methods include membrane surface and materials modification. The mechanism, characteristics of blending, surface chemistry treatment and grafting polymerization were showed. It was evident that the solution blending of membrane materials is the main trend in the modification of PVDF membranes to hydrophilic performance.
