Multicolor Electrochromic Camouflage

Not Available This SBIR project will develop MicroCoating Technologies' novel open atmosphere process to synthesize state-of-the art nano-powders with 50% to 90% processing cost reductions compared to classical techniques. This process will also enable numerous nano-powder compositions that are inaccessible by conventional techniques. In Liquid Combustion Vapor Condensation (LCVC), low-cost, environmentally friendly, metal-bearing reagents are dissolved in solvents that also serve as compustible fuel. Using MCT'S innovative nebullizer, this solution is atomized to form submicron droplets, which are then combusted in a torch, forming vapor. The condensable species thus formed nucleate homogeneously as aerosol nano-powders that are then collected in dispersion media. Premixed precursor solutions allow great versatillity in synthesizing a wide variety of compound nano-powders of very uniform size and composition. The LCVC method will be developed to produce nano-powders that will be collected as colloidal dispersions, a convenient form for handling and subsequent processing. The powders will be characterized for microstructure, stoichiometry and physical properties as a function of process variables. Applications will be developed in near net shape ceramics, powder coating, and rheological fluids. Success will lead to a Phase II, tens of kilograms per hour capable, effort to scale and optimize the LCVC process for low cost production of nano-powders in Phase III.
