Graphene

General Graphene manufactures graphene using the Chemical Vapor Deposition (CVD) technique. This “bottom-up” graphene synthesis method is enabled by a controlled processes that consistently delivers high quality graphene.

In this process, hydrocarbon gases decompose at high temperature, on a transition metal foil, such as copper or nickel. The reaction causes the carbon to deposit on the metal surface, and the growing graphene crystals merge together as the foil moves through the roll-to-roll conveyor to form a continuous single or multi-layer atomic structure.

Unlike exfoliated graphene and reduced graphene oxide that are in a form of powders and used as additives in plastics and coatings, General Graphene’s single or multi-layer continuous graphene sheets remain on a metal substrate, or are transferred to a substrate of interest (polymers, metals, ceramics, etc.). Our large-area continuous CVD graphene provides distinct advantages for barriers and films in comparison to graphene in a powder form. The resulting graphene is produced in 4 main forms:
