We propose to produce a highly durable, biocidal, and chemical-agent reactive CARC-type coating for military vehicles, equipment, and high-touch surfaces. Our approach is based on a water-reducible polyurethane coating chemistry to which we will add components that will polymerize in with the resin to add a low surface energy function that will repel both aqueous and organic liquids. This will make both bio- and chemical agents including pathogens less likely to stick to the coating as they will tend to slide off under the influence of gravity, wind, or rain/washing. The coating will also contain nanoscale additives to actively decontaminate both chemical agents and pathogens, including bacteria, viruses, and spores. The nature, concentration, and method of inclusion of the low-energy and reactive materials is such that they will persist for years even when the coating is exposed to harsh environmental conditions and abrasion. Our plan includes synthesis of novel materials, coating formulation, and a comprehensive set of test protocols for bio and chem agent simulant decontamination.
