Naturally extracted graphene from Eucalyptus bark

naturally extracted graphene
A new method for producing graphene was recently developed by scientists at RMIT University, Australia, and the National Institute of Technol­ogy, Warangal, India. The technique uses Eucalyptus bark extract and is less expensive and more sustainable than existing synthesis techniques, accord­ing to researchers. 

Cost of graphene production

RMIT lead scientist Suresh Bhargava says the new tech­nique could lower the cost of production from $100 per gram to just 50 cents per gram. Professor Vishnu Shanker from the National Institute of Technology, Warangal, says the “green” chemistry avoids the use of poisonous reagents, possibly paving the way for the use of graphene in biocompatible materials. When tested in a supercapacitor, the graphene created by the new technique matched the performance and quali­ty of traditional graphene.
