Valeri Leich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Functionalized graphene, method for producing a functionalized graphene, and its use
    Patent number: 12454459
    Abstract: A process can be used for the functionalization of graphene material by mixing graphene material with at least one silane. The functionalized graphene material is useful, for example, in thermoplastics.
    Type: Grant
    Filed: June 15, 2021
    Date of Patent: October 28, 2025
    Assignee: Evonik Operations GmbH
    Inventors: Valeri Leich, Jonas Hönig, Julian Teichmann, Silvia Blank-Shim, Stefan Schumann, Verena Breuers, Patrik Stenner
  • POLYALKYLENE OXIDES AS DISPERSANT FOR GRAPHENE MATERIAL
    Publication number: 20240351883
    Abstract: A polyalkylene oxide having at least one aromatic radical is a dispersant for a graphene material. A process for dispersing graphene material is developed where the abovementioned polyalkylene oxides are employed as the dispersant. Compositions including the abovementioned dispersant and graphene material are produced.

  • HIGHLY LOADED TRANS-POLYOCTENAMER-GRAPHENE COMPOSITE MATERIAL, METHOD FOR ITS PRODUCTION AND USE THEREOF
    Publication number: 20240301147
    Abstract: A process can be used for production of trans-polyoctenamer-graphene composite material having a high filler content, from a trans-polyoctenamer and graphene material. The highly filled trans-polyoctenamer-graphene composite material is useful, for example, in the automotive sector, in heat exchangers, in housings, encapsulations, plain bearings, in 3-D printing heads for heat removal, injection moulded parts, electronics applications, hose systems, membranes, fuel cells, cable systems, indoor and sports apparel, EM protection, and orthopaedics.

  • COMPOSITIONS COMPRISING A GRAPHENE-BASED MATERIAL AS LUBRICANT ADDITIVES
    Publication number: 20240034855
    Abstract: Nanoparticle compositions contain a graphene-based material. A preparation process involves providing several components and milling a mixture. The nanoparticle compositions can be used as a lubricant additive to improve tribological performance, in particular to improve anti-friction and anti-wear performance on metal parts. A corresponding lubricant composition contains these nanoparticle compositions.
