Nanorods/nanofibers of polyaniline were synthesized via liquid-liquid interfacial polymerization process using ammonium persulphate as an oxidizing agent. Para-toluene sulphonic acid (p-TSA) was used as a dopant during the polymerization process. The spectroscopic characterization (UV-Vis and FT-IR) confirms the presence of conducting emeraldine salt phase of the polymer. The morphological studies were carried out using FE-SEM analysis.
