Graphene is exfoliated from flake graphite material, a two-dimensional crystal composed of carbon atoms that is only one atomic thick. Due to its excellent optical, electrical and mechanical properties, graphene has a wide range of applications. So is flake graphite and graphene related? The following Furuite graphite editor analyzes the relationship between flake graphite and graphene:
1. The extraction method of graphene mass production is not mainly obtained from flake graphite, but from carbon-containing gases such as methane and acetylene. Although the name has the word graphite, the production of graphene is not mainly derived from flake graphite. Instead, it is obtained from carbon-containing gases such as methane and acetylene. Even the current research method is extracted from the growing plant tree, and now there is a method of extracting graphene from tea trees.
2. Graphite flakes contain millions of graphene. Graphene actually exists in nature. If there is a relationship between graphene and flake graphite, then graphene is superimposed layer by layer to form graphite flakes. Graphene is a very small single-layer structure. It is said that one millimeter of flake graphite contains about 3 million layers of graphene, and the fineness of graphene can be seen. To use a visual example, the words we write on paper with pencils contain several or tens of thousands of layers of graphite. ene.
The method for preparing graphene from flake graphite is simple, with few defects and oxygen content, high graphene yield, moderate size, and low cost, and is suitable for large-scale industrial production.
