  • Stable IR transparent conductive graphene hybrid materials and methods of making
    Patent number: 11225713
    Abstract: A method of making a transparent conductive graphene hybrid, comprising the steps of providing a PMMA/Graphene hybrid, functionalizing the PMMA/Graphene hybrid, providing a transparent substrate, oxidizing the transparent substrate, treating the oxidized substrate and forming a functionalized substrate, applying the PMMA/Graphene hybrid to the functionalized substrate, removing the PMMA, and forming a transparent conductive graphene hybrid. A transparent conductive graphene hybrid comprising a transparent substrate, wherein the transparent substrate is oxidized, and wherein the transparent substrate is treated with TFPA-NH2 to form a functionalized substrate, and a layer of graphene on the functionalized substrate.
    Type: Grant

  • Optical applications of nanosphere metasurfaces
    Patent number: 10280310
    Abstract: A monolayer film of nanoparticles can formed from a fluid mixture by combining nanoparticles dispersed in water with a water-miscible organic solvent and a molecular ligand comprising a head group with affinity for the nanoparticle, and introducing the fluid mixture to a substrate in the presence of an air/fluid interface, thereby causing a monolayer film of nanoparticles to form on the substrate. Such monolayers films can include metallic nanoparticles such as gold, and possess substantially uniform spacing over at least a one centimeter length scale. The films are metasurfaces effective to cause a range of linear refractive index of from around unity at 700 nm to 10 at 1500 nm. Such metasurfaces might find utility, for example, as ultrafast (picosecond scale) switches at wavelengths useful for telecommunications.
