  • Publication number: 20220250914
    Abstract: A method of electrochemical exfoliation, may include: electrochemically exfoliating a parent material comprising coke, wherein the electrochemically exfoliating comprises introducing the parent material into a porous chamber, applying pressure to the porous chamber to thereby compress the parent material in the porous chamber, and applying a potential bias to the parent material while at least a portion of the parent material is in contact with an electrolyte solution to produce a mixture of exfoliated material and unexfoliated parent material, wherein the exfoliated material comprises exfoliated graphene; and separating at least a portion of the exfoliated material from the unexfoliated parent material.

  • Publication number: 20210395091
    Abstract: Methods and reactors for electrochemically expanding a parent material and expanded parent materials are described. Current methods of expanding parent materials incompletely-expand parent material, requiring expensive and time-consuming separation of expanded parent material from unexpanded parent materials. This problem is addressed by the methods and reactor for electrochemically expanding a parent material described herein, which during operation maintain electrical connectivity between the parent material and an electrical power source. The resulting materials described herein have a greater proportion of expanded parent material relative to unexpanded parent material compared to those made according to others methods.

  • Publication number: 20200354531
    Abstract: A method of fabrication processing a pre-preg material includes applying electromagnetic heating to a composition including a fiber and a resin. The electromagnetic heating is conducted with at least one fringing field capacitor utilizing radio frequency (RF) alternating current (AC) and controlling cross-linking of the resin in the composition via the electromagnetic heating.

  • Publication number: 20200317957
    Abstract: A non-contact method of joining two components via direct heating of a thermoset adhesive includes applying the thermoset adhesive to at least a first component of the two components. The thermoset adhesive includes a susceptor to reacts in the presence of an electromagnetic field. The method includes placing the first component and a second component of the two components in proximity to an electromagnetic field. In some aspects, the method includes placing the first and second components in proximity to an electromagnetic field of a capacitor. The susceptor interacts with the electromagnetic field to heat the thermoset adhesive via resistive heating. In some aspects, a method of direct-contact heating of the thermoset adhesive includes attaching electrodes to a film comprising the adhesive. The components being joined together are not directly heated by the electromagnetic field, and as a result experience much lower temperatures than the thermoset adhesive.

  • Publication number: 20200180219
    Abstract: The invention relates to additive manufacturing systems and methods using thermally cross-linkable materials. The thermally cross-linkable material includes at least one thermally cross-linkable polymeric material and an amount of at least one electromagnetic energy susceptor therein. A system with at least one print head and an electromagnetic energy generator is provided to produce electromagnetic energy in the area of the thermally cross-linkable material after being dispensed from the print head. This causes heating of the electromagnetic energy susceptor to cause curing of the thermally cross-linkable material.

  • Publication number: 20200009850
    Abstract: A microwave-induced heating of CNT filled (or coated) polymer composites for enhancing inter-bead diffusive bonding of fused filament fabricated parts. The technique incorporates microwave absorbing nanomaterials (carbon nanotubes (CNTs)) onto the surface or throughout the volume of 3D printer polymer filament to increase the inter-bead bond strength following a post microwave irradiation treatment and/or in-situ focused microwave beam during printing. The overall strength of the final 3D printed part will be dramatically increased and the isotropic mechanical properties of fused filament part will approach or exceed conventionally manufactured counterparts.

  • Patent number: 9534319
    Abstract: Methods for dissolving carbon materials such as, for example, graphite, graphite oxide, oxidized graphene nanoribbons and reduced graphene nanoribbons in a solvent containing at least one superacid are described herein. Both isotropic and liquid crystalline solutions can be produced, depending on the concentration of the carbon material The superacid solutions can be formed into articles such as, for example, fibers and films, mixed with other materials such as, for example, polymers, or used for functionalization of the carbon material. The superacid results in exfoliation of the carbon material to produce individual particles of the carbon material. In some embodiments, graphite or graphite oxide is dissolved in a solvent containing at least one superacid to form graphene or graphene oxide, which can be subsequently isolated. In some embodiments, liquid crystalline solutions of oxidized graphene nanoribbons in water are also described.
