Abstract: PURPOSE: In a method of modifying a surface of polymer membrane by ion assisted reaction, the surface of the polymer membrane is processed according to the dose of the ion irradiation and the kind of the ion beam, thereby varying the membrane surface to hydrophilicity. In addition, the size of the pores is controlled according to the irradiation dose of the ion beam, thereby enabling water penetration or electrolyte transmission. The surface modification does not change the characteristics of the membrane itself. Since the surface characteristics are merely changed, even if the membrane is used for a long time, the membrane characteristics do not deteriorate. Moreover, the size of the pores can be adjusted, thereby easily controlling porosity of the various kinds of polymer membranes requiring the selective penetrability. Also, the electrolyte penetrability is remarkably improved. CONSTITUTION: The surface modification method for a polymer membrane by using an ion assisted reaction to control the size and number of pores on the surface of the polymer membrane and to form hydrophilic groups on the polymer membrane, comprises irradiating an ion beam to the polymer membrane; and injecting simultaneously a reaction gas.
