An antimicrobial material including a substrate and an antimicrobial mixed metal oxide, mixed metal sulfide, or mixed metal oxysulfide in and/or on the substrate is described, as well as antimicrobial coating materials and coatings formed therefrom. The antimicrobial material may be constituted in an antimicrobial surface of a surface-presenting substrate, to combat transmission and spread of microbial disease, e.g., disease mediated by microbial pathogens such as bacteria, viruses, and fungi. Antimicrobial mixed metal oxide, mixed metal sulfide, or mixed metal oxysulfide as described may be contacted with microorganisms to effect inactivation thereof.

Antimicrobial compositions and films are provided comprising a polymer and antimicrobial nanoparticles evenly dispersed in the polymer. The antimicrobial nanoparticles comprises an ionic antimicrobial agent and a support agent that localizes the ionic antimicrobial agent to surfaces of the support agent, and wherein the support agent releases the ionic antimicrobial agent through chemical exchange. In this manner, the antimicrobial nanoparticles act as a stored source of antimicrobial agents. The polymer configured to allow the ionic antimicrobial agent released by the support agent to permeate or migrate through the polymer and to the surface of the composition or film, thereby maintaining antimicrobial properties on the surface of the composition for film over an extended time.

Antimicrobial chemical compositions comprise an aluminum phosphate (AlP) solid dispersed within a binding polymer, wherein one or more bioactive materials are disposed within AlP forming a bioactive-AlP complex. The complex may comprise the bioactive material chemically bonded with the AlP, physically combined with the AlP, or a combination of both. The complex may be formed according to precipitation, condensation and sol-gel methods of forming. The complex is engineered to provide a controlled delivery of the bioactive material or a constituent thereof upon exposure to moisture to give a desired level of antimicrobial resistance to a film or composite formed from the composition of at least about 30 μg/m.sup.2, and may also provide a desired degree of corrosion resistance through the release of passivating phosphate anion. Such antimicrobial chemical compositions provide an improved degree of active, long-term resistance to a broad range of micro-organisms when compared to known antimicrobial chemical compositions.
