Abstract
Metal nanoparticle agglomerates may render the surface of an article biocidal toward microorganisms. Articles having a biocidal surface may comprise a coating comprising metal nanoparticle agglomerates adhered via an adhesive to at least a portion of a surface of the article. A coating formulation comprising metal nanoparticle agglomerates may be applied to the surface of an article to accomplish the foregoing.
Claims19
An article comprising:
- a coating comprising metal nanoparticle agglomerates dispersed in a dissolvable or degradable polymer, wherein the dissolvable or degradable polymer comprises at least one of polyvinyl alcohol, polylactic acid, and polyglycolic acid,
- wherein the metal nanoparticle:
- agglomerates are dispersed in the dissolvable or degradable polymer at about 0.5 to about 25 wt. % with respect to the polymer mass;
- and
- wherein the coating is adhered via an adhesive to at least a portion of a surface of the article.

A method comprising:
- applying a coating formulation comprising a plurality of metal nanoparticle agglomerates dispersed in a dissolvable or degradable polymer, wherein the dissolvable or degradable polymer comprises at least one of polyvinyl alcohol, polylactic acid, and polyglycolic acid upon a surface of an article;
- wherein the metal nanoparticle agglomerates are dispersed in the dissolvable or degradable polymer at about 0.5 to about 25 wt. % with respect to the polymer mass;
- and
- adhering the metal nanoparticle agglomerates to the surface via at least an adhesive to form a coating upon the surface of the article.
1 more element
An article comprising:
- a coating comprising metal nanoparticle agglomerates and metal salt compounds, wherein the metal nanoparticle agglomerates comprise copper nanoparticles, and wherein the coating is adhered via an adhesive to at least a portion of a surface of the article;
- wherein the nanoparticle agglomerates and metal salt compounds are dispersed in a dissolvable or degradable polymer, wherein the dissolvable or degradable polymer comprises at least one of polyvinyl alcohol, polylactic acid, and polyglycolic acid;
- and
- wherein the metal nanoparticle agglomerates are dispersed in the dissolvable or degradable polymer at about 0.5 to about 25 wt. % with respect to the polymer mass.
