WATER FLUX POLYMER MEMBRANES |
摘要 |
The invention relates to a polymer membrane composition having improved water flux and stable pore size. The water flux is improved by increasing the hydrophilicity of the membrane using a matrix polymer blended with controlled architecture amphiphilic block copolymers. Preferred membranes are those having a fluoropolymer matrix and acrylic amphiphilic block copolymers. The addition of the amphiphilic block copolymers are especially useful in microfiltration and ultra filtration membranes when used in water filtration. |
