Graphene has a two-dimensional structure of a carbonaceous new material. Graphene has excellent electrical, thermal and mechanical properties. Graphene oxide (GO) is a unique material with various oxygen containing functionalities such as epoxide, carbonyl, carboxyl and hydroxyl groups. Interest in GO increased dramatically after graphene, It was initially hoped that GO might be a synthetic precursor to graphene.
Reduced Graphene Oxide(rGO) is produced from reducing Graphene Oxide thermally, chemically, or through IR or UV irradiation to obtain a powder form. rGO is used in several scientifically important applications that include graphene research, batteries, biomedical, supercapacitators, printable graphene electronics.
Expanded graphite is produced from natural graphite flakes with well-ordered high-crystalline structure. Expanded graphite is highly useful in Chemical and Petrochemical industries, Mechanical Engineering, High-Temperature Furnaces, Automotive Industry, Energy Storage, Thermally Conductive Construction Materials, etc.
Sri Lanka is the only country in the world that produces commercially viable vein graphite for export. High-grade, crystalline vein graphite that is unique to Sri Lanka is in turn transformed into graphene which is used for lithium batteries, fuel cells, nuclear, and solar power devices, the demand for which steadily on the rise.
