Abstract:Surface metallized polymers were widely used in many fields due to their excellent properties. Since the adhesion of metal film to the base polymer is usually poor, their practical applications was limited. In order to solve this problem, several surface modification techniques were employed to modify the surface properties of polymer. The reason of adhesion weakness was analyzed. The progress of polymer surface modification techniques, such as ion implantation, plasma treatment, ion beam irradiation, chemistry, photo-chemistry and excimer laser etching was reviewed. The modification effects and mechanisms of these techniques were also compared. At last, the direction and problems of industrial application were prospected on the basis of current research status.
