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 a bioactive complex comprising metal ions complexed with a ligand, wherein the ligand is selected from the group consisting of imidazole, substituted imidazole, ammonia, and combinations thereof, wherein the bioactive complex is chemically bonded to an amorphous aluminum phosphate to form the chemical composition, the chemical composition having an engineered porosity to provide a controlled release of the metal ions therefrom of from about 10 to 1,000 ppm upon contact of the complex with moisture, wherein the porosity is characterized by at least one of:
A bioactive-aluminum phosphate composition comprising amorphous aluminum phosphate and a bioactive material chemically bonded to the amorphous aluminum phosphate, wherein the bioactive material comprises a complex formed from metal ions complexed with a ligand, wherein the ligand is selected from the group consisting of imidazole, substituted imidazole, ammonia, and combinations thereof, and wherein the composition provides a controlled release of the metal ions therefrom of from about 5 to 1,000 ppm upon contact of the complex with moisture.
