Abstract:
Reactive compositions are provided, having biocidal and chemical decontamination/neutralization properties, comprising a hygroscopic polymer and an active, which are useful in a variety of commercial, healthcare and military applications and a wide variety of contaminants, including without limitation chemical and biological warfare agents. The reactive compositions are renewable or rechargeable after use by exposure to an additional application of the active and do not require removal, disposal or replacement of the originally applied composition. Methods for preparing and applying the reactive compositions are disclosed.

Claim (Index 2):
A method of providing a renewable reactive film coating, having biocidal and chemical deactivation properties against biological and chemical warfare agents, to the surface of an object or article, consisting of the steps of:\n a. providing a solution consisting of i) a non-cross-linked, water soluble polyvinylpyrrolidone dissolved in water, or ii) a non-crosslinked, water soluble polyvinylpyrrolidone dissolved in water and methanol, wherein the polyvinylpyrrolidone has a molecular weight of 10 K, 58 K, 360 K or 1300 K and is present in an amount ranging from about 1 to about 10 wt %, based on the total weight of the renewable reactive film coating; b. mixing the polyvinylpyrrolidone solution with an active consisting of aqueous solution of hydrogen peroxide to form a mixture, wherein the aqueous hydrogen peroxide solution is a 10 wt. % or 20 wt. % solution; c. applying the mixture to the surface of the object or article; d. drying the mixture in air to form a film; and, e. renewing the biocidal and chemical decontamination properties of the film, after fouling, or exhaustion or decay of the hydrogen peroxide active due to contact with biological or chemical warfare agents, by exposing the film to vaporized hydrogen peroxide of at least about 400 ppm for at least 30 minutes.
