Patents by Inventor Yonghong CHENG

Yonghong CHENG 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).

  • Patent number: 11724940
    Abstract: The present invention provides a method for forming a graphene film through horizontally tiling and self-assembling graphene, including: proportionally adding toluene and alcohol into a graphene aqueous solution to be fully and uniformly mixed; then pouring the mixture into a vacuum filtration device, wherein when a solution in a filter flask forms a layered solution system with upper and lower layers, graphene is confined at an interface and tiled horizontally under a shear force at the interface to allow (002) planes of graphene to gradually become parallel to the interface, and graphene to be self-assembled to form the graphene film; and activating the suction filtration device to remove the solution, to obtain a graphene film with the (002) planes parallel to each other at a microscopic level on a filter paper.
    Type: Grant
    Filed: November 14, 2018
    Date of Patent: August 15, 2023
    Assignee: XI'AN JIAOTONG UNIVERSITY
    Inventors: Jinying Zhang, Jialiang Huang, Yehe Shi, Xuewen Zhao, Yonghong Cheng
