Abstract
In the present study a polymerization route for the synthesis of polyaniline (PANI) salts adopted. Polyaniline synthesized by solvent free technique i.e. chemical oxidative polymerization method using HCl as dopant and ammonium peroxidisuplate (APS) as oxidizing agent. The fabrication of multiwalled carbon nanotubes (MWCNTs)/PANI composites memebrane by a filtration and flash welding method. MWNTs are treated with acid i.e. functionalisation of MWCNT to acquire better distribution in the composite membranes. PANI-nanofibers with a unique electrical property are obtained by chemical oxidative polymerization of aniline. PANI and PANI/MWCNT characterized by XRD, FTIR, UV-vis, SEM, TGA, I-V Curve. The electrical conductivity is found to be increased in PANI/MWCNT composites than pure PANI. These results indicates that the further more improvement in material consistency and reduction in defect states, for further use the PANI/carbon nanotubes material can be used to fabricate organic electronic devices.
