Polypyrrole nanoparticles were synthesized by chemical polymerization method using ammonium persulphate as an oxidant. The synthesized polypyrrole nanoparticles were characterized by FT-IR, UV-Visible, FESEM and CV. The structure of polypyrrole nanoparticles were confirmed by FT-IR spectroscopy. The UV-Vis spectra of polypyrrole nanoparticles show p-p* and n-p* transitions. The morphological properties were characterized by FESEM and it shows that the synthesized polymer has agglomerated morphology. The electrochemical properties of the polypyrrole nanoparticles were studied by cyclic voltammetric method. It is reasonable to expect that the synthesized polypyrrole nanoparticles will exhibit promising applications in the field of electrochemical sensor.
