Patent number: 11355259Abstract: 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.Type: GrantFiled: October 8, 2020Date of Patent: June 7, 2022Assignee: University of ConnecticutInventors: Douglas H. Adamson, Steven Woltornist, Andrey V. Dobrynin

Patent number: 11004606Abstract: The present disclosure provides advantageous composite films/coatings, and improved methods for fabricating such composite films/coatings. More particularly, the present disclosure provides improved methods for fabricating composite films by trapping at least a portion of a layered material (e.g., hexagonal boron nitride sheets/layers) at an interface of a phase separated system and then introducing the layered material to a polymer film. The present disclosure provides for the use of boron nitride layers to increase the properties (e.g., dielectric constant and breakdown voltage) of polymer films. The exemplary films can be produced by an advantageous climbing technique. Exemplary boron nitride films are composed of overlapping boron nitride sheets with a total thickness of about one nanometer, with the film then transferred onto a polymer film, thereby resulting in significant increases in both dielectric and breakdown properties of the polymer film.Type: GrantFiled: July 17, 2018Date of Patent: May 11, 2021Assignee: University of ConnecticutInventors: Douglas H. Adamson, Zhenhua Cui, Andrey V. Dobrynin

Patent number: 9685261Abstract: Advantageous films and coatings (e.g., transparent conductive films), and improved methods for fabricating such films and/or coatings, are provided. The improved methods for fabricating transparent conductive films/coatings may involve trapping at least a portion of a layered material (e.g., graphene sheet(s) or layer(s) of graphite) at an interface of a phase separated system (e.g., at an interface of two non-mixing solvents). Transparent, one to four layer, conductive films/coatings of pristine natural flake graphene are produced by kinetically trapping graphene sheets at an interface of a phase separated system (e.g., at an oil/water interface).Type: GrantFiled: April 9, 2014Date of Patent: June 20, 2017Assignee: University of ConnecticutInventors: Douglas H.
