ABSTRACT:
Electrochromic coating solutions are prepared by reacting a transition metal with a mixture of hydrogen peroxide and an organic acid. The resulting transition metal-peroxy acid product is esterified by reacting with lower carbon alcohols to produce a peroxyester-transition metal derivative. This derivative in solution in lower carbon alcohols provides a working solution into which a substrate having a conductive surface is preferably dipped and removed at a rate sufficient to give a coating of a desired thickness over the conductive surface. Spray or spin coating can be used to apply the coating to the conductive surface of the substrate. The coating is then dried and is externally fired in an oven to complete the necessary reactions to yield an electrochromic oxide coating having exceptional electrochromic properties.
