Manufacturing process for graphene powder containing charged tetrafluoroethylene-hexafluoropropylene polymer

Abstract

The invention belongs to the field of inorganic chemistry, and particularly relates to a manufacturing process for graphene powder containing a charged tetrafluoroethylene-hexafluoropropylene polymer.The manufacturing process comprises the following steps: production of a graphene dispersion liquid; grinding and stripping of the graphene dispersion liquid; and drying and solidifying of the graphene dispersion liquid into powder. A formula for the graphene dispersion liquid is composed of the following components in percentage by mass: 71.8% of deionized water, 0.3% of a polyether siloxane copolymer wetting agent, 0.3% of an organic silicon defoamer, 0.3% of a Kathon preservative, 1% of PVP, 2% of CTAB, 0.3% of a fluorine surfactant, 12% of a tetrafluoroethylene-hexafluoropropylene polymerdispersion liquid and 12% of wormlike graphite. The charged tetrafluoroethylene-hexafluoropropylene polymer dispersion liquid and the fluorine surfactant are added in the manufacturing process of graphene powder, so material composition is optimized, graphene is efficiently stripped, and graphene with relatively high purity, large size and a few-layer structure is finally formed. The process hasthe advantages of simple production process, high production efficiency, short reaction time and the like, optimizes material composition, and reduces production cost.

Description

technical field [0001] The invention belongs to the field of inorganic chemistry, and in particular relates to a production process of graphene powder containing charged tetrafluoroethylene-hexafluoropropylene polymer. Background technique [0002] Graphene has unique physical and chemical properties. However, tiny graphene cannot really exert its superior properties. Therefore, research on the preparation of large-size and high-efficiency graphene is necessary. Since the advent of graphene in 2004, how to efficiently prepare it has attracted the close attention of researchers, and theories and methods for preparing graphene have emerged in an endless stream. However, the preparation of ordinary few-layer graphene now uses chemical chloride salts as intercalation agents or penetrants. These intercalation agents have low stripping efficiency and long reaction time. These materials are not easy to remove and will affect the ability to resist corrosion in the future. [0003] ...
