3 Terms and definitions

The following terms and definitions apply to this document:

3:1 graphene graphene graphene layergraphenelayer single-layer graphene;monolayergraphene

A single carbon atom is combined with three surrounding carbon atoms to form a honeycomb structure of carbon atom monolayer:

Note 1: It is an important building block of many carbon nanoobjects:

Note 2: Since graphene has only one layer, it is often called single-layer graphene: Graphene is abbreviated as 1LG to distinguish it from double layer graphite, which is abbreviated as 2LG:

ene and few-layer graphene, abbreviated as FLG:

Note 3: Graphene has boundaries and has defects and grain boundaries where carbon-carbon bonds are broken:

3:2 graphene powder graphenepowder

It is a powder that is mainly composed of graphene and related two-dimensional materials and has a black or brown appearance:

Note: Graphene powder includes single-layer graphene (1LG), double-layer graphene (2LG), few-layer graphene (FLG), graphene nanosheets (GNP), and mechanical exfoliation stone:

Graphene, chemically dissociated graphene, small molecule synthetic (CVD, PVD) graphene, reduced graphene oxide (rGO), graphene oxide (GO), etc:
