Large Scale Production of Graphene Oxide

प्रकार:  Product
आईपीआर स्थिति:  Patent
में सुरक्षित:  India
आवेदन / उपयोग करता है: 

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.

मुख्य तकनीकी सुविधाएँ होड़: 

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%

पर्यावरण पर विचार: 

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.

प्रमुख कच्चे माल का उपयोग किया जा करने के लिए:  Natural flake graphite (preferably 100 mesh), sulphuric acid, potassium permanganate, hydrogen peroxide, hydrochloric acid.
प्रमुख उपकरणों:  Mechanical stirrer, Glass reactor (customized design), distilled water plant, freeze dryer
Techno Economic:  Graphene Electronics Market worth $1512.10 Million by 2020 as per Market Survey. Energy storage (LIB and Supercapacitor) application is also expected to be the fastest growing segment, registering a CAGR of 93.2% during the forecast period.
प्रौद्योगिकी पैकेज:  CSIR-CMERI will not provide raw materials and the equipment required for the graphite oxide production, purification, drying, storage, etc.
सामग्री विवरण: 

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.

स्तर / विभाग के कौशल:  200 g/batch
