Plating catalyst and method
View Patent ↗A catalyst solution includes a precious metal nanoparticle and a polymer having a carboxyl group and a nitrogen atom. The catalyst solution is useful for a catalyzing an electroless process for plating metal on non-conductive surfaces.
1. A solution comprising a precious metal nanoparticle and a polymer, the polymer comprises a carboxyl group and a nitrogen atom within a repeating unit of the polymer and a mole ratio of the precious metal nanoparticle to the carboxyl group of the polymer is 1:0.1 to 1:10.
2. The solution of claim 1 , wherein the polymer is a polyamino acid.
3. The solution of claim 1 , wherein the polymer is polyaspartate.
4. The solution of claim 1 , wherein the precious metal is silver, gold, platinum, palladium, rhodium, ruthenium or osmium.
