Graphene is a two-dimensional crystal made of carbon atoms only one atom thick, stripped from a flake graphite material. Graphene has a wide range of applications due to its excellent properties in optics, electricity and mechanics. So is there a relationship between flake graphite and graphene? The following small series of Analysis of the relationship between flake graphite and graphene:
Flake graphite
1. The extraction method for mass production of graphene is not mainly obtained from flake graphite, but from carbon-containing gases such as methane and acetylene. Despite the name, graphene production does not primarily come from flake graphite. It’s made from carbon-containing gases like methane and acetylene, and even now there are ways to extract graphene from growing plants, and now there are ways to extract graphene from tea trees.
2. Flake graphite contains millions of graphene. Graphene actually exists in nature, if the relationship between graphene and flake graphite, then graphene layer by layer is flake graphite, graphene is a very small monolayer structure. One millimeter of flake graphite is said to contain about three million layers of graphene, and the fineness of graphene can be seen, to use a graphic example, when we write words on paper with a pencil, there are several or tens of thousands of layers of graphene.
The preparation method of graphene from flake graphite is simple, with less defects and oxygen content, high yield of graphene, moderate size, and low cost, which is suitable for large-scale industrial production.
