In a paper published July 26 in the journal Nature, researchers led by Rod Ruoff, John Evans Professor of Nanoengineering in the Robert R. McCormick School of Engineering and Applied Science, report on the development of "graphene oxide paper."
“The mechanical, thermal, optical and electrical properties of graphene are exceptional,” says Ruoff. “For example, the stiffness and strength of these graphene-like sheets should be superior to all other materials, with the possible exception of diamond.”
Paper Title: Preparation and characterization of graphene oxide paper
