Abstract
A method for making an optically clear, colorless, transparent, electrically conductive coating by vacuum deposition is disclosed. The method involves depositing a first layer of titanium suboxide, a second layer of silver or gold, and a third layer of titanium suboxide, and treating the coating with an oil, wax, or other organic material before exposure to an ordinary atmosphere of air in order to control the rate of subsequent oxidation of the titanium suboxide. The coating deposited on a rigid transparent substrate such as glass or plastic, or on a flexible transparent plastic substrate subsequently laminated to a rigid transparent substrate, is useful for electrically heating windows.
