Abstract

The invention discloses a method for preparing a composite of graphene and carbon nanotubes by discharging between electrodes, wherein an anode comprises a carbon material and a metal-containing material; the metal-containing material is selected from oxides of transition metal or rare earth elements, inorganic salts or organic salts or a mixture thereof, or a mixture composed of one or more than one of the above materials and one or more than one of metal Fe, Ni, Mo, Cr or Y. The invention also discloses a composite of graphene and carbon nanotubes prepared by the method of the invention.

Description

technical field [0001] The invention relates to a carbon nanocomposite material and a preparation method thereof. Background technique [0002] Carbon exists in many forms, including common graphite, diamond, amorphous carbon, and recently discovered carbon 60, carbon nanotubes, and graphene. Although these materials are all composed of carbon elements, their structures and properties vary greatly. Graphene is a single-layer graphite or multi-layer graphite material composed of single-sheet graphite. Carbon nanotubes are tubular structures composed of single-layer graphene curls, and can be single-walled carbon nanotubes or multi-walled carbon nanotubes. Graphene and carbon nanotube materials have many excellent properties, such as extremely high electrical conductivity and mechanical properties, and the composite material of the two at the nanometer level will have better properties than a single material in some aspects. Therefore, a simple and feasible large-scale prep...
