Manufacture of graphene platelets
Few layer graphene oxide can be prepared on intensive oxidation of powdered graphite involving either the Brodies, Hofmann, Staudenmaier or Hummer method.
Few layer reduced graphene oxide is available through an intensive reduction of GO with, for instance, hydrazine or hydrogen. Generally, production of rGO from GO requires very strong reducing agents applied in either chemical, electrochemical thermal or photothermal procedures. In chemical synthesis either hydrazine, hydroquinone, sodium tetrahydridoborate and other non-toxic, “green” reagents are in use.
Syntheses GO in NANOMATERIALS LS
GO is available in the scale up to 1 kg monthly with a modified Hummers method.
It was developed within the R&D activity of the NANOMATERIALS LS Enterprise and belongs to its intellectual property.
The production scale can readily be expanded on request.
Syntheses rGO in NANOMATERIALS LS
A strong reducing agent applied to GO provided rGO platelets (the synthesis of rGO is available in the scale up to 1 kg monthly).
The procedure is an intellectual property of NANOMATERIALS LS Enterprise.
The manufacture scale can readily be expanded on request.
