Graphene Fluoride Powder is an important new type of graphene derivative. Compared with graphene, fluorinated graphene, although the hybridization mode of carbon atoms is changed from sp2 to sp3, it also retains the lamellar structure of graphene. Therefore, fluorinated graphene not only has a large specific surface area as graphene, but at the same time, the introduction of fluorine atoms greatly reduces the surface energy of graphene, greatly enhances hydrophobic and oleophobic properties, and improves thermal stability, chemical stability and resistance. Corrosion ability. These unique properties of fluorinated graphene make it widely used in anti-wear, lubricating, high-temperature corrosion-resistant coatings, etc. At the same time, due to the long band gap of fluorinated graphene, it is used in nanoelectronic devices, optoelectronic devices, and thermoelectric devices. The field has potential application prospects. In addition, because the fluorinated graphene-based fluorocarbon material has a developed specific surface and pore structure, and the difference in fluorine content has an adjustable energy band structure, it has unique electrical conductivity and is used in lithium primary battery cathode materials. It has the characteristics of large contact interface with electrolyte and fast lithium ion diffusion. The lithium primary battery using fluorinated graphene as the cathode material has the advantages of high energy density, high and stable discharge platform, wide operating temperature range, and extremely long storage life. , It has great application potential in aerospace and high-end civilian fields.
