Graphene: The new wonder coating
27 September 2012
Researchers from Monash University and Rice University in the USA applied an microscopically thin layer of graphene to copper at temperatures between 800 and 900 degrees, using a technique known as chemical vapour deposition, and tested it in saline water.
They heralded their findings as a possible paradigm change in the development of anti-corrosion coatings.
Initial experiments were confined to copper, but research was already underway on using the same technique with other metals. This would open up uses for a huge range of applications, from ocean-going vessels to electronics: anywhere that metal is used and at risk of corrosion, even in harsh weather conditions. Such a dramatic extension of a metal’s useful life could mean tremendous cost savings for many industries.
A graphene coating can make copper nearly 100 times more resistant to corrosion.
