Self-Decontaminating Chemical Agent Resistant Coating (CARC) Technology (BRIEFING SLIDES)

Abstract

Inovatia Labs is developing a family of coatings that incorporate a pigment that promotes oxidation of contaminants by several mechanisms, including absorption of visible light and catalytic activation of atmospheric oxygen. Topical application of ethyl 2-chloroethyl sulfide (CEES) and of triethyl phosphite (TEP) as a challenge resulted in 50% conversion of CEES and TEP into the respective oxides CEESO and TEPO in an hour and a minute, respectively. This suggests capacity to protect against HD and organophosphates. Testing with challenges of E. coli and of B. subtilis spores shows the ability of the coating to suppress colonization of plastic tubing and of water in the tubing, even when 67% of the tubing is wrapped to exclude light, as in a dental irrigation system. Gradual attenuation of moderately large populations in water is also seen. Applications are proposed to maintaining sterility in clean areas, polishing and preservation of potable water, enhancement of chem-bio decontamination procedures on coated surfaces, and as a sensor for biological contamination.
