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/m2, 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.
An antimicrobial chemical composition comprising;
An antimicrobial chemical composition comprising:
A system for providing antimicrobial protection comprising a coating composition applied to substrate and cured to form a film, the coating composition comprising a binding polymer with a bioactive-aluminum phosphate complex dispersed therein, wherein the complex comprises an aluminum phosphate combined with a bioactive material, wherein the bioactive material is combined with a further material selected from the group consisting of ligands, metal oxides, and combinations thereof, and wherein the complex is engineered to provide a controlled delivery of a bioactive constituent when exposed to moisture.
A method for making a bioactive-aluminum phosphate complex comprising the steps of:
