Abstract:
1. A method of making a solid, electrically conductive composite film or layer, comprising: making a suspension comprising individual insulating graphene oxide sheets; introducing particles of a ceramic or a ceramic-precursor to the suspension to form a sol; depositing the sol on a substrate to form a thin film or layer of a gel-like matrix; chemically reducing the thin film or layer to convert at least a portion of the individual insulating graphene oxide sheets to electrically conductive graphene-like sheets; and thermally consolidating the thin film or layer to form the solid, electrically conductive composite thin film or layer, wherein the solid, electrically conductive composite thin film or layer possesses an optical transparency of at least about 94 percent transmittance within a wavelength range from 380 nm to 1000 nm.
