Researchers from the University of Exeter have discovered that GraphExeter — a material adapted from the ‘wonder material’ graphene, which is the thinnest substance capable of conducting electricity, at a thickness of just one atom — can withstand prolonged exposure to both high temperature and humidity. This could “revolutionize the electronics industry” as the lead researcher, engineer Dr Monica Craciun said.
The research showed that the material could withstand relative humidity of up to 100 per cent at room temperature for 25 days, as well as temperatures of up to 150C — or as high as 620C in vacuum.
The previously unknown durability to extreme conditions position GraphExeter as a viable and attractive replacement to indium tin oxide (ITO), the main conductive material currently used in electronics, such as ‘smart’ mirrors or windows, or even solar panels. The research also suggests that GraphExeter could extend the lifetime of displays such as TV screens located in highly humid environments, including kitchens.
