Graphene Nanosheet /nanoplatelets refers to the carbon layer more than 10 layer, thickness within 5-100nm thin deposit of Graphene layer,also known as Graphene Nanosheets.
Graphene Nanoplatelets keep the original planar carbon graphite six-member ring conjugate crystal structure, have excellent mechanical strength, conductivity, thermal conductivity, and good lubrication, high temperature resistant and corrosion resistant properties.Compared with the ordinary graphite,graphene nanoplatelets thickness is at the nanoscale range, and its radial width can reach several to dozens of micrometers, with oversize diameter/thickness ratio.
