Abstract
Light transmissive, electrically conductive cadmium stannate films on plastic substrates are greatly improved with respect to their adherence to the substrate if the film is deposited on a substrate which has been precoated with a metal oxide, such as silicon dioxide or titanium dioxide.
Claims8
In the process for coating a polymeric substrate with a light transmissive, electrically conductive film of cadmium stannate, the improvement which comprises first coating the substrate with a film of a metal oxide, selected from silicon monoxide, silicon dioxide, titanium dioxide, tantalum oxide, antimony oxide, magnesium oxide, chromium oxide and vanadium oxide.
An electrically conductive, light transmissive device consisting of an electrically conductive, light transmissive film of cadmium stannate coated on a polymeric substrate pre-coated with a film of metal oxide selected from silicon oxide, dilicon silicon, titanium dioxide, tantalum oxide, antimony oxide, magnesium oxide, chromium oxide and vanadium oxide.
