Wet-chemical polyaniline nanorice mass-production for electrochemical supercapacitors

One pot run mass-production of polyaniline (PANI) nanorice is carried out using a simple room temperature ingenious low temperature wet-chemical method. Different bondings are identified using Fourier transform infrared spectroscopy analysis. Crystalline structure, due to presence of well-defined rings in selected area electron diffraction pattern, and nanorice morphology, from the scanning electorn miscropy photoimages, of as-prepared PANI are confirmed. Using high-resolution trasmission electron microscopy digital photoimage 0.46 nm and 0.37 nm fringe widths are monitored. Surface area of 41.06 m2 g−1 is justified from the adsorption–desorption isotherms. The PANI nanorice electrode reveals 17.33 W h kg−1 energy density and the 480 W kg−1 power density due to significant inner charge contribution (68.28 C g−1) compared to outer charge.

► One pot runs mass-production of polyaniline nanorice using simple wet-chemical method.
► Crystalline structure, of sharp ring-type selected area electron diffraction pattern.
► Good stability in specific capacity due to higher inner charge contribution.
