Abstract
Transition metal nitrates such as nickel nitrate are dissolved in monoalcohols having from 1 to 5 carbon atoms. The coatings are applied to a substrate material and fired to convert the coating to an electrochromically active state.
Claims42
A method for preparing an electrochromic coating on a substrate, consisting essentially of:
- forming a coating solution by contacting at least one transition metal nitrate compound with at least one monohydric alcohol having from 1 to 5 carbon atoms;
- coating the surface of said substrate with said coating solution to provide a coating thereon of a desired thickness;
- and
- firing said coating to an electrochromically active state.

A method for preparing an electrochromic coating on a substrate, comprising:
- forming a coating solution comprising at least one monohydric alcohol having from 1 to 5 carbon atoms, from 5 to 20 weight/volume percent of at least one transition metal nitrate and from 5 to 60 weight/volume percent of ethyl acetate;
- coating the surface of said substrate with said coating solution to provide a coating thereon of a desired thickness;
- and
- firing said coating to an electrochromically active state.
