Forget buckyballs and carbon nanotubes, graphene is the next big thing in carbon chemistry. Graphene sheets just one atom thick are electrically conducting and could be used to make new kinds of microelectronic devices. Now, Rodney Ruoff and colleagues at Northwestern University, Evanston, Illinois, have found a novel way to convert regular graphite into graphene embedded in a polymer matrix to form an electrically-conducting composite. The team has circumvented the issue of newly formed graphene sheets sticking together by devising a sonication technique to turn graphite oxide into a graphene-polymer composite. A reduction step introduced prior to polymer-graphene coagulation leads to the formation of the electrically conducting product. The researchers say that under the microscope their composite materials look like ice cubes full of pieces of crumpled paper.
