Single-layer graphene powder physical method

Overview
Graphene is a two-dimensional carbon nanomaterial consisting of carbon atoms arranged in a hexagonal honeycomb lattice. Its unique properties enable diverse applications across multiple industries. The material first attracted significant attention in 2004 when scientists Andre Geim and Konstantin Novoselov successfully isolated a single layer of graphene—a breakthrough that earned them the Nobel Prize in Physics in 2010.

Monolayer graphene comprises carbon atoms bonded through sp² hybridization, forming a continuous two-dimensional structure with a C–C bond length of 0.142 nm, bond angle of 120°, and a theoretical thickness of only 0.35 nm. It is among the strongest known materials and exhibits exceptional electrical and thermal conductivity, mechanical strength, and unique optical characteristics, including transparency and nonlinear behavior.
