Researchers at the University of Technology, Sydney, in Australia, have developed a composite material based on graphite that is as thin as paper and ten times stronger than steel. The material has the potential to revolutionize the automotive, aviation, electrical and optical industries, according to Professor Guoxiu Wang, who supervised the research team. The graphene paper (GP) has exceptional thermal, electrical and mechanical properties. Lead researcher Ali Reza Ranjbartoreh, said, “No one else has used a similar production and heat testing method to find and carry out such exceptional mechanical properties for graphene paper. We are definitely well ahead of other research societies. The exceptional mechanical properties of synthesised GP render it a promising material for commercial and engineering applications. Not only is it lighter, stronger, harder and more flexible than steel it is also a recyclable and sustainable manufacturable product that is eco-friendly and cost effective in its use.” The paper could allow the development of lighter and stronger cars and planes that use less fuel, generate less pollution, are cheaper to operate, and ecologically sustainable. The production of graphene paper would also benefit the mining industry in Australia, as Australian mines have immense graphite resources. The team’s findings were published in the Journal of Applied Physics. The article can be viewed online at the link below.
