Scientists develop high-quality graphene from soybean
Scientists from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have made world’s strongest material graphene commercially more viable by using soybean.
They have developed a novel “GraphAir technology” which transforms soybean oil, a renewable, natural material into graphene films in a single step.
Earlier, graphene was produced in a highly-controlled environment with explosive compressed gases that required long hours of operation at high temperatures and extensive vacuum processing. This production process was costly and was major roadblock in its commercialisation.
About GraphAir technology
- The technology grows graphene film in ambient air with a natural precursor, making its production faster and simpler. Soybean oil breaks down into a range of carbon building units when heat is applied. It makes it essential for the synthesis of graphene films.
- Significance: This unique technology makes graphene fabrication fast, simple, safe, potentially scalable and integration friendly. It results in good and transformable graphene properties, comparable to graphene made by conventional methods. It is expected to reduce cost of graphene production and improve uptake in new applications. Besides, it can also help to produce graphene from waste oil, leftover from cooking.
What is Graphene?
Graphene is a carbon material that is one atom thick. It is the world’s strongest and lightest known material derived from carbon. It has high conductivity and excellent electronic, mechanical, thermal and optical properties. It is used in many applications ranging from miniaturised electronics to biomedical devices, water filtration and purification, renewable energy, sensors, personalised healthcare and medicine etc. It also used to improve battery performance in energy devices, to cheaper solar panels.
