METHOD FOR ELECTROLESS PLATING OF A PRECIOUS METAL

摘要

Process for forming a precious metal layer (5) on a surface of a substrate (1) comprising steps of: providing a substrate (1); activation of a surface of said substrate (1) by wetting the said surface with a suspension (2) of precious metal nanoparticles (3) in a solvent so as to deposit precious metal nanoparticles (3) thereupon, said solvent comprising at least one organic solvent; immersion of the thus-activated surface in an aqueous solution (4) comprising at least one precious metal salt so as to deposit a precious metal layer (5) on the said surface.
