Abstract:
The method of preparing continuous thin films of noble metals upon porous substrate surfaces which includes the steps of:(a) selecting a porous electrically insulative substrate and mounting the substrate within a reaction chamber housing a plasma reactor;(b) selecting a monomer or comonomer precursor of a noble metal;(c) providing a pair of spaced apart electrodes within said reaction chamber in a configuration for creating a plasma glow reaction within said reaction chamber;(d) applying RF energy across said electrodes to create a plasma glow zone therebetween;(e) maintaining said plasma glow while simultaneously supporting said plasma glow through the introduction of a plasma supporting gas in the presence of said monomer or comonomer precursor within said reaction zone with the continuation of said plasma glow causing said precursor to convert to dissociated form so as to release said noble metal from said precursor to form a component consisting essentially of said noble metal and thereby deposit said noble metal component in elemental form as a film of said noble metal onto the surface of said substrate.
