Problems solved by technology

[0002] Carbon materials come in the form of graphite, diamond, activated carbon, carbon fiber, graphene, etc. Among them, only graphene is a two-dimensional material. Graphene is expensive and a single sheet of graphene is relatively small, so it is difficult to promote and apply it on a large scale.

Abstract

A production method of a carbon film, mainly heating the carbon source raw material into liquid, the liquid carbon source raw material forms a layer of carbon source raw material thin layer on the surface of the high-temperature and high-density liquid in the melting tank, and the carbon source raw material thin layer is heated and carbonized into Solid carbon film, the carbon film can be further graphitized at high temperature to become a graphite film.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a novel two-dimensional carbon material and a production method thereof. Background technique [0002] Carbon materials come in the form of graphite, diamond, activated carbon, carbon fiber, graphene, etc. Among them, only graphene is a two-dimensional material. Graphene is expensive and a single sheet of graphene is relatively small, making it difficult to promote and apply it on a large scale. Contents of the invention [0003] The purpose of the present invention is to provide a new two-dimensional carbon material that is relatively low-cost and can be manufactured on a large scale. Put the carbon source material on the surface of immiscible high-density liquid to form a thin layer of carbon source material. The thin layer of carbon source material is heated and carbonized to form a solid carbon film. The carbon film can be further graphitized at high temperature to become a gra...
