Abstract

A method for metalizing a polymer substrate and a polymer article prepared thereof. First a polymer substrate having a base polymer and at least one metal compound dispersed in the base polymer is provided. A surface of the polymer substrate is then irradiated with an energy beam such that a water contact angle of the surface of the polymer substrate is at least 120°. And then the surface of the polymer substrate is subjected to chemical plating.
