In the paper "Experimental and theoretical studies on the composite composed of graphene oxide and polyaniline", we report theoretical and experimental results on graphene oxide – polyaniline composites. Experimental results in this study were obtained by using different techniques: X-ray diffraction (XRD), Scanning electron microscope (SEM) and from cyclic voltammetry. The theoretical results were acquired using method of density functional theory (DFT). | 26896 Hien Thi Tran and Hung Van Hoang Elixir Chem. Phys.

Both methods reveal that there is an existence of graphene oxide Received in revised form polyaniline due to the interaction between oxygen functional groups of graphene oxide 21 August 2014 and polyaniline. The intercalation of polyaniline into layers of graphene oxide expands Accepted 3 September 2014 the space distance of layers in graphene oxide. The presence of polyaniline in composites can be proved by scanning electron microscope SEM and cyclic K ey w or d s voltammograms of obtained composites. The formation of graphene oxide polyaniline Graphene oxide was also proved by theoretical calculation of adsorption energy when polyaniline Polyaniline interacts with graphene oxide Nanocomposite 2014 Elixir All rights reserved Electrochemical method. Introduction considered to reinforce the electrochemical capacitance of GO Graphene has been the major focus of recent research to material. However electrochemical polymerization of exploit an sp2 hybrid carbon network in applications such as monomers on an electrode surface offers many advantages over capacitors cell images sensors devices drug delivery and chemical methods. The obtained product is a solid does not solar cell due to its unique electronic mechanical and thermal need to be extracted from the initial monomer oxidant solvent properties. In addition graphene is an ideal material for mixture and is .
