Popis:	An epoxy resin membrane in which carbon fibers are vertically arranged in array format was electrochemically oxidized to remove carbon fibers and to create microholes of diameter of the carbon fiber (4-7μm). Carbon fiber tips remained at one end of the holes. The microhole membrane possesses an acidic function at the surface of carbon fibers and hence is a charged membrane. The flow flux of water depended on the acidity of an aqueous solution and it increased when the solution was made an acidic.Etching rate of PAN-based carbon fibers was much faster than that of mesophase carbon fibers.
