For a long time, Morion Nanotech has adhered to the core of customized graphene, carried out industrialization layout in the two major sectors of thermal management materials, new energy and devices, and built an industrial chain cluster with application enterprises as the main body. Understanding the formation mechanism and intrinsic properties of graphene at the atomic scale is the key to maintaining technology drive and meeting demand traction. Precise control of the structure and electronic properties of graphene materials at the nanoscale provides theoretical guidance for customized graphene, and provides technical support for the application of graphene in the fields of sensor elements, field-effect transistors, high-speed electric switches, etc., which is an important layout of Morion Nanotech's graphene development strategy.

After making important progress in the precise structure and band manipulation of graphene nanosemiconductors in 2022 (Angewandte Chemie International Edition, 2022), the R&D team of Morion Nanotech has recently made another major breakthrough in this field. Graphene is composed of six-membered rings, and the exploration of the motion law of benzene, the smallest six-membered ring structure, can help understand the formation mechanism of graphene. The R&D team of Morion Nanotech directly observed the reaction migration process of benzene ring on metal surfaces such as Au (111) through scanning tunneling microscopy (STM) and atomic force microscopy (AFM), and proved this reaction process by first principles (DFT) calculations, which helps us to better understand the formation mechanism of graphene, so as to "customize" the preparation of high-quality and high-performance graphene materials. The results were published in the top international journal Nature Communications (Chinese Academy of Sciences Double 1 Zone TOP, Impact Factor 23.20) with the title of "Real-space imaging of a phenyl group migration reaction on metal surfaces". The paper was supported by the National Natural Science Foundation of China and the Dongguan Innovation Team Introduction Project, and Dr. Cai Jinming, the leader of the Dongguan Innovation Team, and Dr. Lu Jianchen, the core member, were the co-corresponding authors of the paper.

Based on a deep understanding of the formation mechanism of graphene, Morion Nanotech has realized the customized preparation and large-scale production of various graphene raw materials such as graphene oxide (GO) cake, graphene oxide (GO) powder, reduced graphene oxide (RGO), nano-graphene semiconductor, etc., and has achieved large-scale mass production and application in graphene thermal conductive film/vapor chamber, graphene micro-nano cavity superconducting film, graphene micro-nano cavity phase change vapor chamber, graphene conductive agent, graphene-based lithium-ion battery and other products. Morion Nanotech will adhere to the development core of customized graphene, and continue to provide original support for the application and development of graphene.
