Development of the Surface Modification of Polyacrylonitrile and Acrylonitrile Based Copolymers Membranes

In order to improve the hydrophilicity and biocompatibility for polyacrylonitrile (PAN) and acrylonitrile-based copolymers membranes,researches have being taken on and some good results were obtained.The development of the surface modification of these membranes was introduced in this article.The methods of surface chemical modification and surface bionic modification were emphasized.
