  • Process and apparatus for preparing transparent electrically conductive coatings
    Publication number: 20030049384
    Abstract: A process and apparatus for producing a transparent, electrically conductive coating onto a substrate. The process includes: (a) operating heating and atomizing devices to provide a stream of super-heated fine-sized metal liquid droplets into a coating chamber in which the substrate is disposed; (b) introducing a stream of oxygen-containing gas into this chamber to impinge upon the stream of super-heated metal liquid droplets and exothermically react therewith to produce substantially nanometer-sized metal oxide clusters; and (c) directing the metal oxide clusters to deposit and form a coating onto the substrate.
