“…10 The advantage of using surface treated RGO as compared to the metal oxides is its high electrical conductivity. 10,12,13 The presence of polar organic groups, including carboxylic acid, epoxy, phenol, and aldehyde functional groups, makes GO a poor conductor of electricity. 10,13 Among the few materials with single atomic sheets, graphene is very useful for fundamental as well as application oriented research due to its remarkable mechanical, electrical and optical properties.…”
