Abstract:
1. An antimicrobial, chemical protective and chemical agent deactivating material comprising: a microporous or nanoporous layer laminated to a continuous film of hydrophilic cross-linked polyvinylalcohol for providing a physical barrier to chemical vapors while permitting moisture to pass through said layer, wherein said microporous or nanoporous layer comprises a polymer selected from the group consisting of polyolefin, polyurethane, and polyester; a chemical deactivation component free of activated carbon deposited on said microporous or nanoporous layer that is laminated to said cross-linked polyvinylalcohol, said chemical deactivation component being dispersed within a carrier material, said chemical deactivation component comprising an effective chemical deactiviating amount of one or more chemically deactivating copper compounds, silver compounds, or elemental silver; and a biocidal component free of activated carbon deposited on said polymer that is laminated to said cross-linked polyvinylalcohol, said biocidal component being dispersed within said carrier material, and said biocidal component comprising an effective biocidal amount of one or more biocidal copper compounds, silver compounds, or elemental silver; wherein said chemical deactivation component contains a chemically deactivating silver compound or elemental silver, or said biocidal component contains a biocidal silver compound or elemental silver.
