Mob Control Vehicles Municipal Solid Waste Segregation Pilot Plant (Click banner to read more) Har Ghar Tiranga 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.
Production yield = 80% Thickness = 1-1.8 nm Number of layers: Few layer (3-4 layers) Dispersible in water and most of the polar organic solvents Oxygen content = 25-28%
Sulphuric acid is used for the oxidation of graphite. The un-reacted acid is stored in a tank, so, there is no environmental concern. Graphene oxide is not toxic and hazardous for the environment.
CSIR-CMERI scientist will demonstrate the graphene oxide production technology (200 g graphite oxidation/batch) at the site of the customer. CSIR-CMERI scientist will also help to buy the machinery/equipment, raw materials, glass ware etc are to be provided to for setting up the process plant.
