Abstract

This paper proposes a novel coating method combining supercritical fluid technology and electroless plating in a hybrid technique. The electroless plating reactions are carried out in an emulsion of supercritical carbon dioxide (sc-CO2) and an electroless plating solution with surfactants. The Ni-P film obtained by this proposed technique was a uniform and conformal film without the pinholes and nodules. The Ni-P film fabricated by our technique was smoother and more uniform than the substrate after pretreatment and the conventional electroless plating.
