Emulsion of metallized particles comprising a compound having a pendant Si-H group
View Patent ↗A particle is formed from a dispersion and includes a compound and a metal disposed on the particle. The compound has the chemical formula R—Si—H. In this formula, R is an organic or inorganic moiety. The particle is also included in a corresponding dispersion. The particle is formed from a method that includes the step of forming the dispersion. The method also includes the step of disposing the metal on the particle.
1. An emulsion comprising a continuous phase and a particle dispersed in the continuous phase, having a metal disposed thereon, and comprising a compound having a pendant Si—H group,
wherein a portion of a total amount of said compound has a pendant Si—OH group that is formed from a reduction reaction between the Si—H pendant group and said metal such that said metal is disposed on said particle via the reduction reaction, and
wherein the particle is a liquid.
2. An emulsion as set forth in claim 1 wherein said metal is agglomerated into nanoparticles.
3. An emulsion as set forth in claim 1 wherein said metal forms a film disposed on said particle.
4. An emulsion as set forth in claim 1 wherein said metal is selected from the group of copper, technetium, ruthenium, rhodium, palladium, silver, rhenium, osmium, iridium, platinum, gold, and combinations thereof.
5. An emulsion as set forth in claim 1 wherein said compound is selected from an elastomer or a resin.
6. An emulsion as set forth in claim 1 wherein said compound is further defined as a monomer.
7. An emulsion as set forth in claim 6 wherein said monomer is selected from the group of silanes, Si—H functional siloxanes, and combinations thereof.
8. An emulsion as set forth in claim 1 wherein said compound is R and R is further defined as a polymerization product of at least a first and a second organic monomer.
9. An emulsion as set forth in claim 1 wherein said compound is R and R is substantially free of silicon.
10. An emulsion as set forth in claim 1 wherein said compound is R and R is further defined as a polymerization product of at least a silicon monomer and an organic monomer.
11. An emulsion as set forth in claim 10 wherein said silicon monomer is selected from the group of organosilanes, Si—H functional organosiloxanes, and combinations thereof.
12. An emulsion as set forth in claim 1 wherein said compound is R and R includes an organopolysiloxane comprising siloxane units having an average unit formula of R x SiO y/2 , wherein R of said siloxane units is an organic group, x is a number of from 0.1 to 2.2, and y is a number of from 1.8 to 3.9.
13. An emulsion as set forth in claim 12 wherein R of said siloxane units has from one to three carbon atoms and at least one functional moiety selected from the group of halogens, aromatics, amines, alcohols, ketones, aldehydes, esters, and combinations thereof.
14. An emulsion as set forth in claim 1 wherein said compound is R and R is further defined as a polymerization product of at least two silicon monomers.
15. An emulsion as set forth in claim 14 wherein said at least two silicon monomers are independently selected from the group of organosilanes, Si—H functional organosiloxanes, and combinations thereof.
16. An emulsion as set forth in claim 1 wherein said compound is R and R is substantially free of carbon.
