  • Patent number: 11085114
    Abstract: Methods for forming thin, pinhole-free conformal metal layers on both conducting and non-conducting surfaces, where the morphology and properties of the metal layers are tuned to meet desired parameters by adjusting the concentration of ionic liquids during the deposition process. The formed metal films contain tunable properties for solar and electronic use and provide specific advantages for non-conducting surfaces, which are otherwise unsuitable for electroplating without the presence of the formed metal films. The disclosed methods do not require the presence of a voltage or external electric field but form the metal films through an electroless technique using electrostatic interactions between negatively charged nanoparticles. In addition, the disclosed methods are compatible with solution phase processing and eliminate the need to transfer the surfaces into a vacuum chamber for a chemical or physical vapor deposition to form a metal layer.

  • Patent number: 10981791
    Abstract: This can be a method of making a high strength composite reinforcing fiber using flat GO flakes coated on a conventional reinforcing fiber. This maintains some the flexibility of the fiber and aligns the flat graphene flakes along the surface of the fiber; this dramatically increases the strength of the fiber. It also allows bonding between overlapping flakes, in contrast to flakes being uniformly dispersed in a host material that is being reinforced and dramatically increases the strength of the host material.

  • Patent number: 10906064
    Abstract: There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

  • Patent number: 10897037
    Abstract: The invention is directed to a process for forming a particle film on a substrate. Preferably, a series of corona guns, staggered to optimize film thickness uniformity, are oriented on both sides of a slowly translating grounded substrate (copper or aluminum for the anode or cathode, respectively). The substrate is preferably slightly heated to induce binder flow, and passed through a set of hot rollers that further induce melting and improve film uniformity. The sheeting is collected on a roll or can be combined in-situ and rolled into a single-cell battery. The invention is also directed to products formed by the processes of the invention and, in particular, batteries.
