摘要:
Disclosed is a device designed for a continuous production of graphene flakes by an electrochemical method. The device consists of an electrochemical unit for generating graphene flakes by an electrochemical exfoliation; a filtration unit for separating the graphene flakes from an electrolyte solution; a guiding path connected to the electrochemical unit and transports the graphene flakes and the electrolyte solution into the filtration unit; a grading collection unit for accepting the separated graphene flakes from the filtration unit and separating the graphene flakes by size. The device can achieve the effect of producing high-quality graphene flakes in mass production electrochemically, continuously and quickly.
摘要:
Disclosed is a method of producing thin graphene nanoplatelets, and the method includes the steps of providing a carbon precursor and a filling material, using the carbon precursor as a binding agent to mix with the filling material thoroughly, producing a composite material through a forming process, performing a heat treatment of the composite material under an atmosphere and at different temperatures to improve the electrical conductivity and adjust to an appropriate binding strength, perform a carbon conversion of the composite material with a good graphite cyrstallinity to produce a layered graphite structure of a thin graphene nanoplatelet precursor, while obtaining high quality graphene by performing an electrochemical process of the thin graphene nanoplatelet precursor, so as to achieve the mass production of the high quality thin graphene nanoplateletes with a low cost.
