Synthesis of nanorod structured polyaniline nanofiber for high electrochemical efficiency

Synthesis of polyaniline (PANI) nanofiber via interfacial polymerization method with ammonium peroxy-disulfate (APS) used as a initiator catalytic agent, aniline& APS molar concentration as a key factor to produce nanofiber without any anionic or cationic surfactant. The optical property of PANI nanofiber was studied by UV-Visible spectroscopy and the obtained absorption peaks around 353 and 634nm. Surface morphology of PANI nanofiber carried by Field emission scanning electron microscopy which gives nanofiber diameter is below 20nm, and Fourier-transform infrared (FTIR) spectra for chemical functional groups. Electrochemical measurement was performed by cyclic voltammetry (CV) and Linear sweep voltammetry (LSV), they shows the high current rate in anodic and cathodic peaks represents high electrochemical property.
