Effect of Zinc Ion on the Electrochemical and Thermal Performance of Polyaniline/Activated Carbon Composites Prepared by In Situ Emulsion Polymerization
Using dodecyl benzenesulfonic acid (DBSA) as surfactant, composites of polyaniline (PANI)/activated carbon (AC) with core-shell structures were prepared by in situ emulsion polymerization in the presence of different concentrations of zinc ion. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) analysis and Fourier-transform IR (FT-IR) spectroscopy were used to analyze morphologies and structures of the composites. Thermal stability of the composites was investigated by thermogravimetric analysis (TGA).The electrochemical properties of PANI/AC composites were studied by galvanostatic charge/discharge tests. The composites exhibited different electrochemical and thermal behavior, which was found to be a function of the concentration of zinc ion.
