CharmGraphene starts mass producing CVD graphene using a roll-to-roll process

Korea-based Charmgraphene has started to mass produce CVD graphene, using its proprietary roll-to-roll process.

CharmGraphene's R2R production system can produce 2 meters of CVD graphene per minute (maximum width 300 mm). According to CharmGraphene, its current CVD graphene capacity is about 8,000 sqm per month. The company says it uses use 6 um thick copper foil which reduces copper foil etching time dramatically compare to 35 um thickness copper foil used by other companies.

CharmGraphene is also developing CVD graphene-based heating elements. The materials are close to commercialization and are flexible, transparent, and thin (
