Organic polymer-inorganic fine particle antimicrobial composites and uses thereof
View Patent ↗An embodiment relates to a composition comprising a noble-metal containing nanoparticle and a polymer located on a surface of the nanoparticle, wherein the polymer is a polycondensation product of a halogenated monomer. Other embodiments relate to the method of making a composition and providing antimicrobial treatment using the composition.
1. A composition comprising a noble-metal containing nanoparticle and a polymer located on a surface of the nanoparticle, wherein the polymer is a poly(alkoxybenzyl) represented as:
2. The composition of claim 1 , wherein the composition exhibits an antimicrobial activity.
3. The composition of claim 1 , wherein the composition dissolves in an organic solvent.
4. The composition of claim 1 , wherein the polymer is located directly on the surface of the nanoparticle, wherein the nanoparticle comprises silver.
5. A method of preparing a composition of a noble-metal containing nanoparticle and a polymer, the method comprising: condensing a halogenated monomer in the presence of the noble-metal containing nanoparticle and forming the polymer from the halogenated monomer on a surface of the noble-metal containing nanoparticle, wherein the method is carried out in a single vessel, and the polymer is a poly(alkoxybenzyl) represented as:
6. The method of claim 5 , wherein the method is carried out at about room temperature.
7. The method of claim 5 , wherein the polycondensation comprises a chemical condensation reaction leading to a formation of the polymer by polymerizing the monomer and releasing water or a molecule.
8. The method of claim 5 , wherein the nanoparticle comprises silver and the monomer comprises an alkoxybenzyl halide.
9. The method of claim 5 , wherein the forming the polymer is carried out without a presence of an external catalyst during the polycondensation of the monomer.
10. The method of claim 5 , wherein the polymer is located directly on the surface of the nanoparticle, wherein the nanoparticle comprises silver.
11. A method of antimicrobial treatment of a material in need thereof, the method comprising treating the material with a composition comprising a noble-metal containing nanoparticle and a polymer located on a surface of the nanoparticle, wherein the polymer is a poly(alkoxybenzyl) represented as:
12. The method of claim 11 , wherein the treating is an antimicrobial treatment.
13. The method of claim 11 , wherein the material is selected from water, waste water, a military equipment, a civilian protection equipment, a soft drink, a detergent, a medical product, an electrical component, an electronics component, and combinations thereof.
14. The method of claim 11 , wherein the treating comprises applying a film or a coating on the material, the film or the coating comprising the composition.
15. The method of claim 11 , wherein the treating comprises reducing an amount of bacteria and/or fungi in or on the material.
16. The method of claim 12 , wherein the antimicrobial treatment produces antimicrobial activity that persists for at least one month.
17. The method of claim 11 , wherein the nanoparticle comprises silver.
