Single-layer graphene powder chemical method

Overview
Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal lattice. Since its successful isolation in 2004 by Nobel laureates Geim and Novoselov, it has attracted broad interest due to its exceptional properties. Monolayer graphene consists of a single layer of carbon atoms with a thickness of only 0.35 nm. It exhibits outstanding electrical and thermal conductivity, mechanical strength, and optical transparency.
