In recent years, conducting organic thin films has attracted considerable attention because of their use in quickly evolving electronic devices such as microbatteries, electrochemical capacitors, and sensors. In the poster, we prepare and investigate a nanostructured multilayer film composed of a conducting polymer; polyaniline (PANI) and reduced graphene oxide (RGO) nanosheet. The graphene oxide nanolayers in the multilayer films are converted to the reduced form RGO by pyrolysis at high temperature or by chemical treatment employing hydrazine and hydroiodic acid. The morphology of PANI/GO before and after reduction is characterized by using AFM, Raman and FT-IR spectroscopy. The sheet resistance of LbL multilayer films assemble on fused silica substrates is measured by using a standard four-point probe method. The potential of using these composites as electrode materials for supercapacitors is tested by standard cyclic voltammetry (CV) and galvanostatic charge-discharge technique. |
