ELECTRODEPOSITION OF SILVER WITH FLUOROPOLYMER NANOPARTICLES |
摘要 |
Electrolytic plating compositions and electrolytic plating processes for the co-deposition of silver or silver alloy with fluoropolymer nanoparticles are provided. The silver or silver alloy composite coating containing fluoropolymer nanoparticles has enhanced functional properties such as a reduced coefficient of friction. The electrolytic plating composition comprises: (a) a silver ion source comprising silver methane sulfonate (Ag-MSA); (b) a complexing agent comprising a compound comprising a nitrogen-containing heterocyclic ring; (c) a pre-mix dispersion comprising fluoropolymer nanoparticles particles having a mean particle size of from about 10 nm and about 500 nm and a surfactant; and (d) an auxiliary surfactant comprising a cationic fluorosurfactant, wherein the composition has a pH of from about 8 to about 14. |
