POLYMER SURFACE MODIFICATION BY HYDROGEN ION ASSISTED REACTION

摘要

PURPOSE: A method for treating surface of high molecular is provided which can maintain hydrophilic functional group under water for a long period thus keep the surface condition very stable, as well as can improve the movement of electrolyte, the rate of electrolysis, and mechanical strength in high molecular separating membrane by using ion assist reaction to treat the surface of high molecule of C, and H or C, H, and O, then increasing the formation of hydrophilic functional groups to the layer beneath the surface. CONSTITUTION: A method for treating surface of high molecular using ion assist reaction characteristically comprises the steps of: irradiating hydrogen having a certain energy to the surface of a high molecular material at the interval of 15-90 centimeter, under vacuum condition, and blowing oxygen as a reactive gas to the surface of the high molecular material, wherein the amount of hydrogen irradiation is in the range of 10¬15-10¬17 ions/cm¬2, and the energy that the hydrogen has is 0.5-1.5keV to activate the surface of the high molecular materials, and wherein the amount of the reactive gas, oxygen can be varied depending on the pump capacity, and the degree of vacuum is set to the range of 30-70 torr.
