  • Thermoelectric polymer aerogels and methods of fabrication thereof
    Patent number: 10522732
    Abstract: This disclosure provides systems, methods, and apparatus related to thermoelectric polymer aerogels. In one aspect, a method includes depositing a solution on a substrate. The solution comprises a thermoelectric polymer. Solvent of the solution is removed to form a layer of the thermoelectric polymer. The layer is placed in a polar solvent to form a gel comprising the thermoelectric polymer. The gel is cooled to freeze the polar solvent. The gel is placed in a vacuum environment to sublimate the polar solvent from the gel to form an aerogel comprising the thermoelectric polymer.
    Type: Grant
    Filed: April 19, 2017
    Date of Patent: December 31, 2019
    Assignee: The Regents of the University of California
    Inventors: Edmond W. Zaia, Madeleine P. Gordon, Preston Zhou, Boris Russ, Nelson Coates, Ayaskanta Sahu, Jeffrey J. Urban
  • Nanostructured layers of thermoelectric materials
    Patent number: 9882108
    Abstract: This disclosure provides systems, methods, and apparatus related to thermoelectric materials. In one aspect, a method includes providing a plurality of nanostructures. The plurality of nanostructures comprise a thermoelectric material, with each nanostructure of the plurality of nanostructures having first ligands disposed on a surface of the nanostructure. The plurality of nanostructures is mixed with a solution containing second ligands and a ligand exchange process occurs in which the first ligands disposed on the plurality of nanostructures are replaced with the second ligands. The plurality of nanostructures is deposited on a substrate to form a layer. The layer is thermally annealed.
