A variety of nanostructures including nanofibers and nanotubes have attracted much attention because of their unique physical and chemical characteristics. In particular, the properties of nanomaterials depend on their size, shape, and dimensionality, which is in contrast with their bulk counterpart. Herein, we synthesized polyaniline nanomaterials of different shapes by using a kind of dispersion polymerization. The nanomaterials were characterized by scanning electron microscopy, ultraviolet-visible spectroscopy, X-ray diffraction, and so forth. Importantly, polyaniline is one of the famous conducting polymers. Therefore, we investigated the dependence of electrochemical properties of the nanomaterials on the shape. As a model system, the nanomaterials were applied to electrodes for supercapacitors. Cylic voltammetry and charge-discharge tests were performed to examine the performance of the nanomaterial electrodes |
