The difference between expanded graphite and ordinary graphene

Expanded graphite, also known as flexible graphite or vermicular graphite, is a new type of carbon material. Expanded graphite has many advantages, such as large specific surface area, high surface activity, good chemical stability, and high temperature resistance. The commonly used preparation process for expanded graphite is to use natural flake graphite as the material, which is first oxidized to form expandable graphite, and then expanded to form expanded graphite. Expanded graphite materials can instantly expand by 150-300 times in volume when exposed to high temperatures, changing from flaky to wormlike, resulting in a loose structure, porous and curved structure, expanded surface area, improved surface energy, and enhanced adsorption of flake graphite. Wormlike graphite can be self embedded between them, making the material have functions such as flame retardancy, sealing, and adsorption. It has wide applications in fields such as life, military, environmental protection, and c
