Abstract
In accordance with one embodiment of the invention, a process for forming an electrically conductive layer is disclosed comprising (i) intercalating colloidal vanadium oxide with a water soluble vinyl-containing polymer, (ii) incorporating the intercalated colloidal vanadium oxide in a coating composition, and (iii) coating the coating composition on a substrate. In accordance with a second embodiment of the invention, a composition for forming an electrically conductive element or layer thereof is disclosed comprising (i) colloidal vanadium oxide intercalated with a water soluble vinyl-containing polymer and (ii) a binder which is distinct from the water soluble vinyl-containing polymer. Intercalation of vanadium oxide gels with water-soluble polymeric species in accordance with of the present invention results in a vanadium oxide gel having improved solution stability and reduced impact of solution aging on conductivity.
