Abstract

The invention relates to a quick preparation method for a graphene oxide film, which comprises the following steps: taking crystalline flake graphite powder as a raw material, taking a piece of plain glass as a film-forming carrier, taking sulfuric acid, sodium nitrate, potassium permanganate and hydrogen peroxide as materials used in a preparation process, taking deionized water as a solvent and taking nitrogen as a protection gas; firstly, preparing a graphene oxide solution in a four-hole boiling flask and using a salpeter solution to flocculate the graphene oxide solution; and then forming a film on the plain glass; and vacuum-drying the film, thereby acquiring the graphene oxide film. The graphene oxide film is 1-2 mu m in thickness and has high strength and excellent toughness as well as excellent breaking strength resistance. The quick preparation method has the advantages that the process flow is short, the speed is high, the operation is simple and the mass production can be realized. The prepared film can be applied to carriers of paper battery and fuel battery catalysts. The quick preparation method is an ideal method for quickly preparing the graphene oxide film.

Description

Technical field [0001] The invention relates to a rapid preparation method of graphene oxide film, and belongs to the technical field of preparation and application of graphene film of graphite carbon material. Background technique [0002] Graphene, also known as single-layer graphite, is a hexagonal honeycomb lattice composed of carbon atoms. It is a two-dimensional material with the thickness of only one carbon atom. Graphene has always been considered a hypothetical structure. It exists alone and stably. In 2004, physicists Andre Heim and Konstantin Novoselov of the University of Manchester in the United Kingdom successfully exfoliated highly oriented graphite to prepare graphene, and thus won the 2010 Nobel Prize in Physics. [0003] Graphene is currently the thinnest and hardest nanomaterial in the world. It is almost transparent. It only absorbs 2.3% of light. It has a thermal conductivity of 5300W / m·K, which is higher than carbon nanotubes and diamonds, and has an electron ...
