Abstract

Interaction of modified polyimide films with agrentium nitrate solutions of various concentrations was studied. Sorption of Ag ions by films is divided into three steps: formation of Ag ion layer on the border of film surface; diffusion inside the films; and final saturation of film by Ag ions. The data are confirmed by calculation of weight of the sorbed Ag ions onto the films with various thicknesses. Electrochemical Ag loading of PI films includes two parallel reactions: film dissolution accompanied by chelation.
