Graphene Manufacturing Techniques - Thomasnet

Other methods for manufacturing graphene are: growing it from a stable carbon source (using thermo-engineering), cutting open carbon nanotubes, carbon dioxide reduction, and graphite oxide reduction. Reduction uses heat by either atomic force microscope or laser to reduce graphite oxide to graphene. It has received some publicity because of the minimal cost of production. However, the quality ...

Graphene - Wikipedia

Graphene (/ ˈ ɡ r æ f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.. Each atom in a graphene sheet is connected to its three nearest neighbors by a σ-bond, and ...
