ELECTROLESS PLATING OF SILVER ONTO GRAPHITE

A one-pot process for the electroless-plating of silver onto graphite powder is disclosed. No powder pretreatment steps for the graphite, which typically require filtration, washing or rinsing, are required. The inventive process comprises mixing together three reactant compositions in water: an aqu...

Beschreibung
Zusammenfassung:	A one-pot process for the electroless-plating of silver onto graphite powder is disclosed. No powder pretreatment steps for the graphite, which typically require filtration, washing or rinsing, are required. The inventive process comprises mixing together three reactant compositions in water: an aqueous graphite activation composition comprising graphite powder and a functional silane, a silver-plating composition comprising a silver salt and a silver complexing agent, and a reducing agent composition.
