Abstract
Provided are materials having antimicrobial properties. The materials include a polymer having incorporated therein a synergistic combination of at least two metal oxide powders, including a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal. The powders may be incorporated substantially uniformly within the polymer. Further, the powders may have substantially different specific gravities and substantially similar bulk densities. In addition, the ions of the metal powders may be in ionic contact upon exposure of the material to moisture. Also provided are methods for the preparation of the materials and uses thereof, including in combating or inhibiting the activity of microbes or microorganisms.
Claims22
A material having antimicrobial properties, said material comprising a polymer having incorporated therein a synergistic combination of at least two metal oxide powders, comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, the powders being incorporated substantially uniformly within said polymer, wherein the powders have substantially different specific gravities and substantially similar bulk densities and wherein the ions of the metal oxides are in ionic contact upon exposure of said material to moisture.
A method for the preparation of a material having antimicrobial properties, said material comprising a polymer having incorporated therein a synergistic combination of at least two metal oxide powders comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, the powders being incorporated substantially uniformly within said polymer, wherein the powders have substantially different specific gravities and substantially similar bulk densities and are in ionic contact upon exposure of said material to moisture, the method comprising the steps of:
- a. processing the at least two metal oxide powders to have substantially similar bulk densities;
- and
- b. mixing said powders with at least one polymer.
