PROCESSES FOR FORMING HYDROPHILIC MEMBRANES AND POROUS MEMBRANES THEREOF

摘要

A process of forming an integral hydrophilic membrane from a porous hydrophobic membrane includes exposing a porous hydrophobic polymer membrane to a plasma, wherein the plasma contains reactive carbon dioxide species configured to covalently bond carboxylic functional groups to a surface of the polymer membrane and form the integral hydrophilic membrane.
