Abstract
The instant disclosure provides a self-adsorbed catalyst composition, a method for preparing the self-adsorbed catalyst composition and a method for manufacturing an electroless plating substrate. The self-adsorbed catalyst composition includes colloidal nanoparticles and a silane compound. Each of the colloidal nanoparticles includes a palladium nanoparticle and a capping agent enclosing the palladium nanoparticle. The silane compound has at least an amino group, and an interaction is established between the amino group of the silane compound and the colloidal nanoparticle. The self-adsorbed catalyst composition provided by the instant disclosure is easy to be prepared. In addition, an electroless plating substrate can be manufactured with an eco-friendly and uncomplicated process based on the use of the self-adsorbed catalyst composition, and an adhesion between an electroless plating metal layer and the substrate can be satisfactory.
