Abstract
There is disclosed a method for surface-modifying a fluorocarbonpolymer-molded article and a method for chemical plating the surface. The method for surface-modifying comprises irradiating the fluorocarbonpolymer-molded article with an ultraviolet laser beam having a wavelength of 250 nm or less, in the presence of hydrazine compound, to make a surface of the said fluorocarbonpolymer-molded article hydrophilic. The surface made being hydrophilic is made lipophilic by chemical treating with an organic acid anhydride. The method for chemical plating comprises chemical plating the surface made being hydrophilic by the above method for surface-modifying, to deposit a metal film on a surface of the fluorocarbonpolymer-molded article.
