- Abstract
Novel hollow tetragonal starlike polyaniline (HTS-PANI) doped with citric acid has been successfully synthesized by hydrothermal method for the first time. Scanning electron microscopy, transmission electron microscopy, UV-visible spectroscopy, Fourier transmission infrared spectroscopy, and X-ray diffraction were employed to analysis the morphology and structure of the obtained PANI. The results show that the HTS-PANI is in semi redox state and highly crystallized, accompanied with good thermal stability. According to the galvanostatic charge-discharge analysis, the specific capacitance of the sample is up to 460 F g at a current density of 0.2 A g in 1 M KCl electrolyte, and retains about 58 % after 1,000 charge-discharge processes at a current density of 5 A g.
