  • Transparent conductive porous nanocomposites and methods of fabrication thereof
    Patent number: 9139917
    Abstract: A nanocomposite material that is both transparent and electrically conductive is provided. The nanocomposite comprises a nanoporous matrix, preferably formed from nanoparticles, that is internally coated with a transparent conductive material to define an internal conductive path within the nanocomposite. The nanocomposite is substantially transparent over a defined spectral range that preferably includes at least a portion of the visible spectrum, and preferably comprises pores with a mean diameter of less than approximately 25 nm. A bilayer may be formed by depositing a layer of a transparent conductive material on top of a nanocomposite layer, or by depositing a second layer of a nanocomposite having different optical properties. The nanocomposites formed using a combination of sequential and/or concurrent deposition techniques are correspondingly discrete and/or continuously varying structures.
    Type: Grant
    Filed: October 15, 2010
    Date of Patent: September 22, 2015
