| 摘 要： | 在含有0.2 mol.L-1苯胺的0.5 mol.L-1H2SO4溶液中,以扫描速度50 mV.s-1,扫描电位为-0.1~0.9 V,采用循环伏安法(CV),在金属Ti基体上,通过控制扫描方式分别得到了颗粒状、纤维状及管-片状的苯胺聚合产物,分析了形成不同形貌聚苯胺的原因,并通过扫描电子显微镜(SEM)、循环伏安法和电化学阻抗谱(EIS)对不同形貌聚苯胺的结构和性能进行了表征.结果表明,不同形貌聚苯胺的形成是由于聚苯胺的成核及生长模式不同,而无论何种形貌的聚苯胺膜都具有很大的比表面积和良好的导电性能,其中,管-片状聚苯胺的膜层阻抗最小,导电性能最好. |

| Abstract: | Polyaniline films on Ti-based metal substrates with granular,fibrillar and tube-slice surface morphology were prepared in a 0.2 mol·L~(-1) aniline solution in 0.5 mol·L~(-1) sulfuric acid by using the cyclic voltammetry method with scanning valtages in the range of-0.1 V～0.9 V at a scanning rate of 50 mV·s~(-1).The electrochemical properties and structure of polyaniline film electrodes were characterized by SEM,cyclic voltammetry(CV) and electrochemical impedance spectra(EIS).The result show that the different surface morphology of polyaniline films has different nucleation and growth mechanism,and polyaniline on Ti-based metal has prodigious surface area and good electrical conductivity.The tube-slice polyaniline has the least film impedance and the best electrical conductivity. |
| Keywords: | Polyaniline Electrochemical polymerization Cyclic voltammetry(CV) Electrochemical impedance spectra(EIS) |
