The world’s strongest material has been made more commercially viable with the development of new technology that transforms soybean oil.

Graphene is a carbon material that is one atom thick. Its thin composition and high conductivity have led to its use in applications ranging from miniaturised electronics to biomedical devices. These properties also enable thinner wire connections, providing extensive benefits for computers, solar panels, batteries, sensors and other devices. Until now, though, the high cost of graphene production has been the major roadblock in its commercialisation.

Graphene is typically grown in a highly controlled environment containing explosive compressed gases, requiring long hours of operation at high temperatures and extensive vacuum processing. Now, however, CSIRO scientists have developed a novel technology that eliminates the need for such a highly controlled environment.

The “GraphAir” technology grows graphene film in ambient air with a natural precursor, making its production faster and simpler. “This ambient-air process for graphene fabrication is fast, simple, safe, potentially scalable and integration-friendly,” said CSIRO scientist Dr Zhao Jun Han, who was co-author of the report published in Nature Communications. “Our unique technology is expected to reduce the cost of graphene production and improve the uptake...
