POROUS MEMBRANE HAVING HYDROPHILIC SURFACE AND PROCESS OF ITS MANUFACTURE |
摘要 |
<p>A composite porous membrane is formed from a porous polymeric membrane having desired bulk properties on which is directly coated a cross-linked polymer having desired surface properties. The composites membrane retains the porosity of the porous polymeric membrane. A preferred composite porous membrane is formed from a porous polyvinylidene fluoride to which is directly coated with a polymer formed of a cross-linked hydroxyalkyl acrylate.</p> |
