Polymeric coatings have been developed that are capable of both detecting and removing hazardous nuclear and heavy metal contaminants from contaminated surfaces. Recent work has focused on coatings for chemical warfare agents based on phosphorus and sulfur.  These coatings consist of strippable polymeric compositions containing blends of polymers, copolymers and reactive agents that can be brushed or sprayed onto a surface as a solution or dispersion in aqueous media.  Upon drying these coatings form strong films that can be easily peeled or stripped from the surface.  When applied to a contaminated surface, these coatings display responsive behavior.  Areas of contamina-tion are indicated by a color change.  As the coatings dry, the contaminant(s) are drawn into and fixed in the polymer matrix.  Subsequent removal of the coating with entrapped contaminants results in some degree of surface decontamination.  Here we report our continued development and investigation of a reactive coatings for the destruction and removal of a variety of chemical warfare agents.
