Graphene is a two-dimensional carbon nanomaterial with hexagonal honeycomb lattice composed of carbon atoms with sp² hybrid orbitals.
In addition, graphite is also a polishing agent and rust inhibitor for glass and paper in the light industry.
Expandable graphite was first discovered by the German Schaufautl. In 1841, Schaufautl immersed natural graphite in a mixture of concentrated HNO3 and H2SO4, took it out and dried it for several hours, and found that graphite had expanded.
Natural flake graphite crystals are scaly; they are metamorphosed under high pressure and are divided into large and fine pieces.
Scale crystals are complete, thin and tough, good physical and chemical properties, good thermal conductivity, temperature resistance, self-lubricity, conductivity, thermal shock resistance, corrosion resistance and other properties.
