DATA SHEET(Graphene)

For the first time in Sri Lanka, now Industrial Technology Institute is in a position to cater your need for superior hi-tech material, Graphene and Graphene Oxide.

Graphene Oxide is an oxidized form of single layer graphite which can be used to produce graphene and it has a high demand in industry worldwide. Sri Lanka is the only country where vein graphite with purity above 99% carbon exists, enabling production of high quality graphene oxide and graphene. Sri Lanka exports graphite mainly as raw material at a lower price or with little value addition, despite the possibility to develop highly value added products.

Scientists from Materials Technology Section developed pure and quality Graphene and Graphene Oxide, suitable for modern applications giving high value addition to our natural resource, graphite.
