Highly ordered polyaniline: synthesis, characterization and electrochemical properties

摘要: Crystallization of semi-crystalline polyaniline has been attempted by altering conditions such as nature dopant acid and oxidant a one-pot chemical polymerization method. The samples were characterized an array analytical techniques. Highly ordered arrangement with sharp peaks was present in the X-ray powder diffraction pattern when ultrasonication monomer solution performed for 2 h before addition ammonium persulfate. emeraldine salt form PANI confirmed this sample from FTIR Raman spectroscopy measurements. Thermal stability evaluated. Aggregation chains evident SEM image. As showed BET surface area 24.31 m2/g, its electrochemical behavior determined performing cyclic voltammetry galvanostatic charge/discharge experiments. It found to possess excellent performances specific capacitance 912.5 F g−1 m−1.
