While some polyaniline (PANI) morphologies have been reported, its synthesis with regular structure in multi-dimensions has met with limited success. Here, well-defined PANI spheres, roses, cloud-like and rhombic plates, layered flowers, columns, blocks, and dendrites were prepared by employing static surfactant systems in a 0.010 M HCl solution at room temperature. The acquisition of these multi-dimensional (MD) nanostructures was a result of that aniline and the newly formed PANI molecules were subjected to a synergistic effect of soft templates and self-assembly process. Detailed electrochemical measurements investigated the capacitance of these MD nanostructures. PANI layered flowers possessed the highest specific capacitance of 340 F g-1 at the current density of 1.0 A g-1 due to their morphologies. Additionally, two factors including the surfactant dosage and the pH value were evaluated to discern their impacts on the PANI morphologies. The method presented herein renders the possibility for fabricating regular MD PANI nanostructures. And these nanostructures meanwhile have a potential to be applied in supercapacitor electrode and energy storage
