聚苯胺/聚砜复合材料的制备及其超级电容性能

通过化学聚合法，制备出盐酸掺杂聚苯胺（PANI），将其与聚砜（PSF）溶液混合，定量滴加到玻碳电极上制得PANI/PSF复合膜电极。 采用扫描电子显微镜、红外光谱以及X射线衍射对其结构和形貌进行表征。 根据循环伏安曲线、恒电流充放电曲线和电化学阻抗，研究了其作为电极的超级电容性能。 结果表明，多孔结构的PANI/PSF复合材料具有良好的电容性能，其比电容可达到497 F/g，并且该超级电容器具有较小的内阻和较好的循环稳定性。

Preparation of Polyaniline/Polysulfone Composite Material and Their Super-capacitive Performance

Polyaniline doped with hydrochloric acid was prepared by chemical polymerization, and polyaniline/polysulfone composite film electrode was obtained by mixing the doped polyaniline with the polysulfone solution, and quantitatively adding the mixture to the glassy carbon electrode. The morphology and structure of polyaniline were characterized by scanning electron microscopy(SEM)，Fourier transform infrared spectroscopy(FTIR) and X-ray diffraction(XRD). The electrochemical properties of supercapacitor were investigated by cyclic voltammetry, galvanostatic charging-discharging and electrochemical impedance spectroscopy. These results show that polyaniline/polysulfone composite with porous structure has good capacitance performance, and a specific capacitance of 497 F/g is obtained. The composite also exhibits lower inter resistance and good cycle stability.
