摘要： The present disclosure relates to a method of electroplating of a silver-graphene composite onto a substrate (1). The method comprises preparing a plating bath (6) comprising: a dissolved water soluble silver salt, dispersed graphene flakes (3), and an aqueous electrolyte (2) comprising a silver complexing agent, a cationic surfactant, and a pH adjusting compound. The zeta potential of the graphene-electrolyte interface in the plating bath is adjusted to be positive and within the range of 10-30 mV by means of the cationic surfactant and the pH adjusting compound. The method also comprises applying a negative electric potential on the substrate surface (4) such that electrophoresis of the graphene flakes occurs and said flakes are codeposited with the silver during electroplating thereof to form a silver-graphene composite coating on the substrate surface.
