摘要： The disclosure relates to a method for characterizing a two-dimensional nanomaterial sample. The two-dimensional nanomaterial sample is placed in a vacuum chamber. An electron beam passes through the two-dimensional nanomaterial sample to form a diffraction electron beam and a transmission electron beam to form an image on an imaging device. An angle θ between the diffraction electron beam and the transmission electron is obtained. A lattice period d of the two-dimensional nanomaterial sample is calculated according to a formula d sin θ≅dθ=λ, where λ represents a wavelength of the electron beam.

摘要： A method for making carbon fiber film includes drawing a carbon nanotube film from a carbon nanotube array. The carbon nanotube film is successively passed through a first room and a second room. A carrier gas and a carbon source gas are supplied to the first room and a carbon layer is formed on the carbon nanotube film located in the first room. The carbon nanotube film with the carbon fiber film is taken into the second room from the first room, and the carbon layer is graphitized.

摘要： A method for making artificial graphite includes placing a graphene film on a surface of a base, to obtain a graphene film/base composite structure. The graphene film includes a first surface and a second surface opposite to the first surface, and the second surface is in direct contact with the surface of the base. The graphene film/base composite structure is placed in a reaction chamber, and a carbon layer is formed on the first surface of the graphene film, to obtain a carbon layer/graphene film/base composite structure. The carbon layer/graphene film/base composite structure is graphitized in an inert gas environment or a vacuum environment to obtain artificial graphite.
