Iran Gains Technical Know-How for Making Lightest Material in World
“Aerographene is the lightest material in the world and it can reduce the weight of equipment and create special properties in them. In batteries and supercapacitors, it increases their capacity and lifespan up to 5 times and reduces environmental risks and weight,” said Arash Qazitabar, a graduate of Amirkabir University of Technology and the manager of the project.
He added that aerographene can also increase the corrosion resistance in different parts, improve the absorption of electromagnetic waves, protect devices and equipment against these waves and reduce their weight, noting that it can also improve the absorption of organic and inorganic pollutants in the sewage.
Qazitabar underlined that the Iranian specialists have gained the necessary expertise in working with this material to such an extent that the engineering capability has been created for various applications, including electromagnetic wave protection, oil and petroleum pollutant absorbers, heavy metal absorbers, lithium-ion battery electrodes and car batteries.
Aerographene or graphene aerogel is the least dense solid known, at 160 g/m3 (0.0100 lb/cu ft; 0.16 mg/cm3; 4.3 oz/cu yd), less than helium. It is approximately 7.5 times less dense than air. Note that the cited density does not include the weight of the air incorporated in the structure.
Graphene aerogels are synthetic materials that exhibit high porosity and low density. Typical synthesis of graphene aerogels involve reducing a precursor graphene oxide solution to form graphene hydrogel.
