  • Patent number: 11355259
    Abstract: The present disclosure provides advantageous graphene/graphite stabilized composites (e.g., graphene/graphite stabilized emulsion-templated foam composites), and improved methods for fabricating such graphene/graphite stabilized composites. More particularly, the present disclosure provides improved methods for fabricating pristine, graphene/graphite/polymer composite foams derived from emulsions stabilized by graphene/graphite kinetic trapping. In exemplary embodiments, the present disclosure provides that, instead of viewing the insolubility of pristine graphene/graphite as an obstacle to be overcome, it is utilized as a means to create or fabricate water/oil emulsions, with graphene/graphite stabilizing the spheres formed. These emulsions are then the frameworks used to make foam composites that have shown bulk conductivities up to about 2 S/m, as well as compressive moduli up to about 100 MPa and breaking strengths of over 1200 psi, with densities as low as about 0.25 g/cm3.

  • Patent number: 11316148
    Abstract: In an embodiment, an active material-based nanocomposite is synthesized by infiltrating an active material precursor into pores of a nanoporous carbon, metal or metal oxide material, and then annealing to decompose the active material precursor into a first gaseous material and an active material and/or another active material precursor infiltrated inside the pores. The nanocomposite is then exposed to a gaseous material or a liquid material to at least partially convert the active material and/or the second active material precursor into active material particles that are infiltrated inside the pores and/or to infiltrate a secondary material into the pores. The nanocomposite is again annealed to remove volatile residues, to enhance electrical contact within the active material-based nanocomposite composite and/or to enhance one or more structural properties of the nanocomposite. In a further embodiment, the pores may be further infiltrated with a filler material and/or may be at least partially sealed.

  • Patent number: 11309100
    Abstract: An electrically conductive, flexible, strain resilient product is produced by mixing metal coated carbon nanotube networks with a liquid polymeric resin to produce a liquid mixture, and the mixture is cured to produce the product. The networks may include welded junctions between nanotubes formed by depositing and melting metal nanoparticles on the nanotubes to form the metal coating. After the mixing step the liquid mixture may be deposited on a flexible substrate in the form of an electrical circuit. The mixing step may further include mixing the composite with a volatile solvent to produce a selected viscosity. Then, a three-dimensional printer may be used to print the product, such as an electrical circuit, on a substrate. The product is cured in an atmosphere that absorbs the solvent. The conductivity of the mixture may be adjusted by adjusting the weight percentage of the metal coated carbon nanotube networks from 50% to 90%, but a preferred range is between 75% and 85%.
