Graphene super-toys last all summer long

posted by Jason Kottke   Mar 25, 2013

Well, this is interesting. Graphene is a substance discovered relatively recently that has a number of unusual properties. In 2004, physicists at the University of Manchester and the Institute for Microelectronics Technology in Russia used ordinary scotch tape to isolate single-layer sheets of graphene. Once isolated, the sheets could be tested for the unusual properties I mentioned. The 2010 Nobel Prize in Physics was awarded for this work.

In 2012, a group of researchers at UCLA discovered they could make single-layer sheets of graphene by coating a DVD with graphite oxide and then “playing” the disc in a plain old DVD drive. And then in a happy accident, they found that graphene has unusually high supercapacitance properties, which could mean that graphene could be used, for example, as a mobile phone battery that lasts all day, charges in a few seconds, and can be thrown into a compost bin after use.
