Descrizione generale

A low dimensional carbon nanoplatelet with a lateral dimension of about 2-3μ and a few layer thick. It is slightly oxidized (content of oxygen around 2%) yielding to a superior dispersion behavior in different solvent/matrix. It has been used with success as anti-corrosion additive in powder coating formulation among other properties.

Commercial graphene nanoplatelets in the form of optically transparent thin films on F-doped SnO(2) (FTO) exhibited high electrocatalytic activity toward I(3)(-)/I(-) redox couple, particularly in electrolyte based on ionic liquid (Z952). The charge-transfer resistance, R(CT), was smaller by a factor
