Graphene properties
This page serves as a graphene cheat sheet, a reference listing all known graphene characteristics along with citations. If you would like to help us improve our list of graphene properties by submitting information which is not listed here, please don't hesitate to e-mail us at contact _AT_ graphene-battery.net. We do not intend this as a commentary page. Rather, our aim is to provide a good, reputable list of graphene properties in one place.
