The study reports some preliminary investigations on the template free synthesis of a scantly investigated polyaniline (PANI) derivative-Phenylenediamine (PDA) by template free method in the presence of Oxalic acid (OA) (dopant), using Ammonium Persulfate as oxidant. Polymerization of Phenylenediamine (PDA) was confirmed by the FT-IR as well as UV–visible studies. The morphology of Phenylenediamine doped with oxalic acid shows nanofibres was confirmed by Scanning electron microscopy (SEM) studies. It is also observed that the change in morphology changes the electrical conductivity. The oxalic acid as dopant has beneficial effect on the electrical conductivity.
