    • The present invention relates to a method for plating the surface of polymer materials with a metal film by treating the surface of polymer materials with cold plasma method to introduce hydrophilic functional groups and then plating the surface of polymer materials with a metal film according to the electroless plating method. The cold plasma treatment reduces the contact angle of the surface of polymer materials to water by 5 to 60°. The surface of polymer materials can be more efficiently plated with the metal film by the additional step of either immersing the polymer material into an organic solvent for 0.1 to 5 minutes or washing the polymer material with ultrasonic washing machine after introducing the hydrophilic functional groups by treatment with cold plasma. The plating method according to the present invention is very stable and readily applicable and can endow new properties which are not possessed by the polymer material itself, including improved appearance quality, improved mechanical properties, improved heat resistance and durability, decrease of absorptivity, rendering the conductivity of heat and electric current, soldering ability and electromagnetic wave shielding effect, etc., to the polymer material. The polymer materials treated by the method according to the present invention have improved performance and can be used in various industrial fields for shielding electromagnetic wave generated from the information processing equipments, preparing printed circuit boards, various forms of electrodes, and antistatic boards and the like.

    • A method for pretreating a surface of a non-conducting material to be plated through precipitation of metal where an adsorbing metal oxide is initially deposited, such as MnO2 or Fe2O3 on the surface, whereafter said surface is treated with a solution of transition metal ions, such as Sn++ ions, and then with a solution of metal ions of a catalytic metal catalyzing chemical plating, such as a metal of the platinum group. The transition metal ions used are selected among such ions that can reduce catalytic metal ions into catalytic metal. The method renders it possible to plate non-conducting materials, such as plastic materials, which cannot or only with great difficulty can be plated by a conventional activation by means of colloidal palladium.
