  • Patent number: 11352481
    Abstract: Methods include producing tunable carbon structures and combining carbon structures with a polymer to form a composite material. Carbon structures include crinkled graphene. Methods also include functionalizing the carbon structures, either in-situ, within the plasma reactor, or in a liquid collection facility. The plasma reactor has a first control for tuning the specific surface area (SSA) of the resulting tuned carbon structures as well as a second, independent control for tuning the SSA of the tuned carbon structures. The composite materials that result from mixing the tuned carbon structures with a polymer results in composite materials that exhibit exceptional favorable mechanical and/or other properties. Mechanisms that operate between the carbon structures and the polymer yield composite materials that exhibit these exceptional mechanical properties are also examined.

  • Patent number: 11345101
    Abstract: A method of forming a polyolefin-perovskite nanomaterial composite which contains oriented electrically and thermally conductive pathways. The method involves milling a polyolefin with particles of a perovskite nanomaterial, molding to forma composite plate, and subjecting the composite plate to an AC voltage. The AC voltage forms oriented electrically and thermally conductive pathways by partial dielectric breakdown of the composite. The presence of the oriented electrically and thermally conductive pathways gives the polyolefin-perovskite nanomaterial electrical and thermal conductivity and dielectric permittivity higher than the polyolefin alone.
