Title: THERMOELECTRIC MATERIALS AND RELATED COMPOSITIONS AND METHODS
Abstract:
A thermoelectric material includes a polymer matrix and a plurality of partially coated particles dispersed within the polymer matrix. Each particle of the plurality has a discontinuous coating of metal on a carbon-based material. A method includes dispersing functionalized particles comprising a carbon-based material in a solvent; providing a metal salt in the solvent; and forming a plurality of distinct metal volumes on a surface of the functionalized particles to form partially coated particles. The distinct metal volumes are thermally insulated from other volumes of the plurality. A composition of matter includes a discontinuous coating of metal on a surface of a carbon-based material. The carbon- based material is selected from the group consisting of graphene oxide and functionalized carbon nanotubes.
