▎ 摘　　要

NOVELTY - Producing an optically transparent and electrically conductive film, comprises: (a) providing a graphene oxide gel prepared from oxidation of a graphitic material in an oxidizing medium, where the graphene oxide gel contains graphene oxide molecules dissolved in a liquid medium; (b) dispersing metal nanowires in the graphene oxide gel to form a suspension; (c) dispensing and depositing the suspension onto a supporting substrate; and (d) removing the liquid medium from the suspension to form the optically transparent and electrically conductive film. USE - The process is useful for producing an optically transparent and electrically conductive film, which is useful as an electrode in electro-optic device, which is a photovoltaic or solar cell, LED, photo-detector, touch screen, electro-wetting display, LCD, plasma display, LED display, a TV screen, a computer screen, or a mobile phone screen (all claimed). ADVANTAGE - The process produces a film that: exhibits an optical transparence of not less than 85% and sheet resistance of not greater than 100 ohm/square (preferably not greater than 50 ohm/square), an optical transparence of not less than 90% and sheet resistance of not greater than 200 ohm/square (preferably not greater than 100 ohm/square), or an optical transparence of not less than 95% and sheet resistance of not greater than 100 ohm/square (claimed); is transparent and has high electric conductivity or low sheet resistance; and is flexible, durable, mechanically strong, environmentally stable, and potentially much less expensive. DETAILED DESCRIPTION - Producing an optically transparent and electrically conductive film, comprises: (a) providing a graphene oxide gel prepared from oxidation of a graphitic material in an oxidizing medium where the graphene oxide gel contains graphene oxide molecules dissolved in a liquid medium; (b) dispersing metal nanowires in the graphene oxide gel to form a suspension; (c) dispensing and depositing the suspension onto a supporting substrate; and (d) removing the liquid medium from the suspension to form the optically transparent and electrically conductive film, which is composed of metal nanowires and graphene oxide having a metal nanowire-to-graphene oxide weight ratio of 1/99 to 99/1, where the metal nanowires contain no surface-borne metal oxide or metal compound and the film exhibits an optical transparence of not less than 80% and sheet resistance of not greater than 300 ohm/square. An INDEPENDENT CLAIM is also included for the optically transparent and electrically conductive film produced by the process, where the film is composed of metal nanowires and reduced graphene oxide with a metal nano-wire-to-reduced graphene oxide weight ratio of 1/9 to 9/1
