    摘要: A method of producing a cation-exchange membrane having roughed surface which is characterized in mixing silica powder with water to give a suspended or pasty mixture, supporting the resultant mixture on art paper or filter paper, drying the mixture to form silica powder layer, adhering with heating and pressing the silica powder layer on surface of membrane composed of perfluorocarbon polymer, and removing the silica powder layer formed on the surface of said membrane with caustic alkali aqueous solution.
