In 2004, Andre Geim at the University of Manchester made a pencil scrawl on a sheet of paper, then used a length of Sellotape to pull off the graphite deposits.
To make the material, the team milled raw graphite by purifying it with chemicals to reshape it into 'nano-structured configurations' which are then processed into sheets of paper.
制造这种物质，该小组把原料石墨磨碎，用化学品净化，把它重塑成“纳米结构”，然后再把它加工成纸张。

In this paper, the surface of graphite fiber is treated continuously by using air-cold plasma.
