PREPARATION OF ORDERED GRAPHENE FILM FROM GRAPHENE OXIDE HYDRO-GEL DEPOSITION BY CHEMICAL CONDUCTION

摘要

Graphene-monolayer of carbon atoms arranged in a honeycomb network is prevalent in many carbonbased materials. It's a flat monolayer of carbon atoms tightly packed into a two-dimensional (2D) lattice, and is a basic building block for graphitic materials of all other dimensionalities. Graphene has been considered to be a hypothetical structure, which can not exist alone, until physicists A.K. Geim and K.S. Novoselovthe in the University of Manchester successfully prepared graphene via striping highly oriented pyrolytic graphite in 2004, and won the 2010 Nobel Prize in Physics. Graphene has excellent thermal, electrical, optical, mechanical and other properties, and is expected to become the next best candidate materials in many areas. But for now, most of graphene preparation processes are complex, its application still in its infancy, and both its preparation and application should be further discussed and studied. So, here, we propose an ordered graphene thin film prepared by a simple technique. A combination of exceptional mechanical strength, thermal stability, high electrical conductivity, and good solubility in water makes this unique material promising for man} technological applications.
