Graphene oxide is extensively used in energy storage devices, polymer composites, desalination of water, conducting ink, aqueous lubrication, nano-coolant, additive for phase change materials, etc. Problem being addressed: The cost of commercially available graphene oxide is very high (Rs. 35,000 for 0.2 g) and thus it is very difficult to use it in the aforesaid areas. Therefore, scaled-up production of graphene oxide at reasonable price without compromising the quality is a challenging task. The developed technology demonstrates the production of graphene oxide starting from natural flake graphite (200 g/batch) without pre-treatment.
