Eucalyptus bark as a source for manufacturing soluble graphene has been developed by Australian and Indian scientists. This is cost-effective and eco-friendly using one of Australia’s most common resources, gum trees.

“A new approach developed by researchers from RMIT University in Australia and India’s National Institute of Technology, Warangal, uses eucalyptus bark extract to synthesise graphene, making it cheaper and more sustainable than current methods. RMIT lead researcher Suresh Bhargava said the new method could halve the current US$100/g cost of production.
 
“Eucalyptus bark extract has never been used to synthesise graphene sheets before and we are thrilled to find that it not only works, it’s in fact a superior method both in terms of safety and overall cost,” said Bhargava, adding the abundance of eucalyptus trees in Australia made it a cheap and accessible resource for producing graphene.
 
The material’s distinctive features make it a transformative material that could be used in the development of better solar panels as well as flexible electronics, more powerful computer chips, water filters and bio-sensors. “It is a remarkable material with great potential in many applications due to its chemical and physical properties and there’s a growing demand for economical and environmentally friendly large scale production,” added the lead researcher….”
 
Chemical reduction is the most common method for synthesizing graphene oxide as it allows for the production of graphene at relatively low cost in bulk. However it relies on reducing agents that are dangerous to people and the environment.
 
Professor Vishnu Shanker, from the National Institute of Technology, Warangal, said eucalpytus-derived ‘green’ chemistry avoids the use of toxic reagents, potentially opening the door to the application of graphene not only for electronic devices but in biocompatible materials.”
