Dodecylbenzenesulphonic Acid Doped Polypyrrole/Graphene Oxide Composite with Enhanced Electrical Conductivity

Abstract

Polypyrrole/graphene oxide (PPyGO) composite was synthesized through in-situ emulsion oxidative polymerization method. The composite was simultaneously doped with dodecylbenzenesulphonic acid doped (DBSA). The reaction parameters were optimized in such a way to get the composite with best possible properties. Thus, the resulting composite showed enhanced conductivity that is 73 S/cm compared to DBSA doped polypyrrole (4.18 S/cm) and graphene oxide (0.57 S/cm). As, conductivity is very important characteristic for practical application of polymeric materials, so, this material with enhanced properties can be used for multiple purposes. It was further characterized through Fourier Transform infrared spectroscopy, X-Ray Diffraction Analysis, Scanning Electron Microscopy and Thermogravimetric Analysis, which showed the successful synthesis of the composite.
