Researchers at Rutgers University have demonstrated a simple microwave-based method for producing high-quality graphene, that can be used in next-gen electronic and energy devices. The proposed microwave treatment is said to produce exceptionally high quality graphene with properties approaching those of pristine graphene.

The team found that heating exfoliated graphene oxide for one second in a 1,000-watt microwave oven (like those used in households across the world) can eliminate virtually all of the oxygen from graphene oxide, yielding graphene in a simple and cost-effective way.
