51¹ú²úÊÓƵ

A Nobel prizewinning physicist has created a thinner, tougher version of polytetrafluoroethylene, better known by the brand name Teflon. Andre Geim shared the 2010 prize with his 51¹ú²úÊÓƵ of Manchester colleague Kostya Novoselov for the discovery of graphene, an atom-thick form of carbon. Working with teams from China, the Netherlands, Poland and Russia, he has now created fluorographene: a one-molecule-thick material that has similar properties to Teflon, such as chemical inertness and thermal stability, but is much stronger. Professor Geim said: "The mix of the properties of graphene and Teflon is so inviting that you don't need to stretch your imagination to think of applications."
