IMPROVING COLOR AND RELEASE PROFILE OF RESIN COMPOSITIONS COMPRISING SILVER NANOPARTICLES

摘要

Methods of forming antimicrobial resin compositions comprising silver nanoparticles are disclosed. Such methods generally comprise: combining a silver-containing material with a resin in situ in the presence of a silver-binding compound; and curing the resin. Antimicrobial polymeric resin compositions formed by said methods have a lighter color than control compositions and also display a slower release of silver ions over time.

主权项

1. A method of forming an antimicrobial resin composition containing silver nanoparticles, said method comprising:
selecting a silver-containing material, an acrylic resin monomer and a solvent that is miscible with the metal-containing material and with the acrylic resin monomer; combining the silver-containing material with the solvent to form a silver-containing material solution; combining a silver binding compound with the acrylic resin monomer to form a mixture; mixing the silver-containing material solution with the acrylic resin monomer mixture in situ to form an acrylic resin monomer solution; forming silver nanoparticles within the acrylic resin monomer solution by curing the acrylic resin monomer solution, wherein the curing process converts the acrylic resin monomer to a polymer; and forming an antimicrobial, resin composition.
