Abstract

The invention discloses a mild discharge preparation method and device for fluorinated graphene, and relates to the technical field of graphene preparation. The present invention overcomes the bonding force of the graphite layer through the chemical carbonization process and the physical stripping process by using an electric field, so that the carbonized graphite carbon is successfully stripped into sheets, so it can be applied to almost all carbon-containing carbon sources, and realizes the guarantee of fluorinated graphene At the same time of high-efficiency and high-quality preparation, the raw materials for its preparation are extended to carbon-based substances, that is, almost all carbon-containing substances can be used as raw materials for this process, and the raw materials have a wide range of sources and low cost. Using active metals as catalysts, power on and preheat first, so that the temperature of the carbon source and the active metal increases to increase the activity of the metal, and then increase the voltage to achieve graphitization of the carbon source. The reaction is rapid and the energy consumption of the reaction is greatly reduced. It has a good conversion rate. , the efficiency of preparing fluorinated graphene powder is high, and the preparation of fluorinated graphene in a low-temperature environment is realized, thereby realizing low energy consumption and reducing the preparation cost.

Description

technical field [0001] The invention relates to the technical field of graphene preparation, in particular to a mild discharge preparation method and device for fluorinated graphene. Background technique [0002] Graphene, a special allotrope of carbon whose carbon atoms pass through sp 2 The hybrid orbitals and π-bonds are tightly and regularly linked to form a honeycomb-like shape with an ideal two-dimensional crystal structure. These unique structural features make graphite have good electrical and thermal conductivity in the layer, and it has good application value in the fields of batteries, catalysis, special lubricants and powder metallurgy. As a new derivative of graphene, fluorinated graphene introduces fluorine atoms on the basis of the two-dimensional planar structure of graphene, so that it obtains many new electrical properties. [0003] It has good hydrophobicity and electronic, optical and mechanical properties, and has incomparable potential application val...
