CSIRO graphene technique creates faster uptake in new applications

The Commonwealth Scientific and Industrial Research Office (CSIRO) has created a new graphene manufacturing process, ‘GraphAir’, which significantly improves graphene uptake in new applications.

Until the CSIRO innovation, graphene was grown in highly controlled environments with explosive compressed gases, long hours of operation at high temperatures, and extensive vacuum processing.

The “GraphAir” technology eliminates the need for a highly controlled environment and grows graphene in ambient air. 

The CSIRO’s Dr Zhao Jun Han, co-author of the study into graphene, said that the GraphAir production process is superior to traditional graphene manufacturing processes.

“This ambient-air process for graphene fabrication is fast, simple, safe, potentially scalable, and integration-friendly,” he said.

 “Our unique technology is expected to greatly reduce the cost of graphene production and drastically improve the uptake of graphene in new applications.”

 The graphene made by the CSIRO is also new – it is composed of soybean and waste oils, which is cheaper to make than traditional graphene.

The CSIRO is looking to partner with industry to find new uses for graphene including replacing gold and silver in solar cells with graphene, extending battery life in energy devices using graphene’s chemical stability and using graphene as an anti-toxic, anti-corrosion coating.
