Coraopolis, Pennsylvania-based Goodfellow Corporation (Goodfellow) is taking graphene and going “green,” offering an ultra-pure, metal-free variant of the industry-disrupting material.
Unlike exfoliation production methods, where graphene is created by separating layers of graphite, Goodfellow’s process involves breaking methane gas – a very potent greenhouse gas – into hydrogen and elemental carbon atoms in a plasma reactor. The carbon atoms recombine into graphene sheets in the hydrogen atmosphere.

The resulting graphene nanoplatelets are very thin, slightly crumpled, and do not stack (unlike exfoliated materials), ensuring optimal electrical, thermal, and mechanical performance. These characteristics make Goodfellow’s “green” graphene an extremely good nanofiller for electronic inks, polymers, metal composites, surface coating, and other metal-sensitive applications.
