<p>A method of coating a substrate with electrochromic coatings comprises dipping a substrate having a conductive surface into, or spraying, or spin coating with, a solution prepared by reacting an anhydrous halide of an electrochromically active transition metal with a C1 to C5 anhydrous alcohol, preferably under a stream of inert gas, at 0 to 80 DEG C. The dipped substrate is removed at a rate necessary to give a desired thickness, and the resulting coating is dried and hydrolysed and further condensed to create an electrochromically active coating.</p> |
