A simple method for assembling graphene films

摘要

Introduction: Although predicted by physics [1] and suggested by few catalytic studies, graphenes, as stable chemical species, have only been established properly at 2004 by Andre Geim and Konstantin Novoselov [2,3] Their work was laureate with the Nobel Prize in Physics 2010. From that time, crescent amounts of studies have emphasize basic and technological aspects of graphenes. Particularly, assemblies of graphene films have attracted much of efforts due to potential applications. However, instrumental techniques as CVD are expensive and demand high controlled experimental conditions [4,5]. To overcome this hurdles some experimental low cost techniques using colloidal graphite oxide films have been carried out using spin coat [6], Langmuir - Blodgett [7], templates [8], casting [9]. This work shows a simple method for assembling graphite oxide films by radial compression using visible light as cure agent.
