New GraphExeter Material Able to Withstand Temperature and Humidity Extremes

January 11, 2015

A resilience to extreme conditions by the most transparent, lightweight and flexible material for conducting electricity could help revolutionise the electronic industry, according to a new study.

Researchers from the University of Exeter have discovered that GraphExeter – a material adapted from the ‘wonder material’ graphene – can withstand prolonged exposure to both high temperature and humidity.

The research showed that the material could withstand relative humidy 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.

These research findings are published in the respected scientific journal, Scientific Reports, on Thursday, 8 January 2015.

Lead researcher, University of Exeter engineer Dr Monica Craciun said: “This is an exciting development in our journey to help GraphExeter revolutionise the electronics industry.

“By demonstrating its stability to being exposed to both high temperatures and humidity, we have shown that it is a practical and realistic alternative to ITO. This is particularly exciting for the solar panel industry, where the ability to withstand all weathers is crucial.”
