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 4):
A method for providing a renewable reactive film coating, having biocidal and chemical decontamination properties against biological and chemical warfare agents, to a surface of an object or article, consisting of the steps of:\n a. applying a hygroscopic polymer solution to the surface of the object or article, wherein the polymer consists of non-cross-linked, water soluble polyvinylpyrrolidone, dissolved in (i) water or (ii) water and methanol to form a solution, 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. processing the polymer solution to form a film; c. exposing the film to an initial charge of an active consisting of chlorine gas; d. air drying the film; and e. renewing the biocidal and chemical decontamination properties of the film, after fouling, or exhaustion or decay of the active due to contact with biological or chemical warfare agents, by exposing the film to additional amounts of chlorine gas.
