Abstract

In 2010 Andre Geim and Konstantin Novoselov won the Nobel Prize in Physics due to their innovative experiments with graphene, a two-dimensional material consisting of carbon atoms with sp2 hybridization. This new material has the thickness of an atom and has outstanding electrical and mechanical properties (NOBEL PRIZE, 2012). Its synthesis may be done by chemical vapor deposition (CVD), micromechanical exfoliation of graphite, electrically insulating epitaxial growth on surfaces or chemical reduction of graphene oxide. In all the procedures mentioned last is the most suitable for obtaining large scale graphene (Liao et al, 2011).Various reducing agents have been employed to obtain graphene from graphite oxide (PARK & Ruoff, 2009) and this work will investigate whether it can be accomplished with flavonoids.
