Description

technical field [0001] The invention relates to a plastic product and a method for selective metallization of the surface of a plastic substrate. Background technique [0002] Selectively form a metal layer on the surface of an insulating substrate such as plastic, and use it as a path for electromagnetic signal transmission, which is widely used in the fields of automobiles, computers, and communications. Various methods can be used to form a metal layer on the surface of an insulating substrate such as plastic. [0003] At present, when selectively forming a metal layer on the surface of a plastic substrate, the metal oxide is usually preset in an insulating substrate such as plastic, and electroless plating is performed after laser irradiation, thereby selectively metallizing the surface of the insulating substrate. . The above-mentioned metal oxides usually use antimony-doped tin oxide, but the use of antimony-doped tin oxide has the problems of poor light absorption p...
