The processing and analysis of graphene and the strength enhancement
Graphene can be treated as a general term for a family of materials. Most commonly used graphene types are pristine graphene (G), graphene oxide (GO) and reduced graphene oxide (rGO). Table 1 compares their differences approximately. Pristine graphene, as its name suggests, has the best and closest properties to 'pure graphene'.
