Abstract
A method for no-silane electroless plating of metal using high adhesive catalyst includes: (a) providing a substrate, and the substrate having a surface which is subjected a surface modification to form a layer of hydrophilic wet chemical oxide; (b) forming a catalyst layer on the layer of hydrophilic wet chemical oxide, the catalyst layer including a plurality of colloid nanoparticles, and each of the colloid nanoparticles including a palladium nanoparticle and a palladium nanoparticle wrapped polyvinyl alcohol polymer; and (c) conducting the electroless plating of metal, and the metal being deposited on the catalyst layer to form an electroless plating metal layer. A substrate including no-silane electroless plating metal layer is also provided.
