摘　　要：采用简单的电化学聚合方法在FTO导电玻璃表面制备了纳米结构的聚苯胺（PANI）和聚吡咯（PPy），用扫描电镜（SEM）图和电化学循环伏安法分析了两种聚合物薄膜的形貌和电催化活性，结果表明，两种聚合物纳米形貌的不同导致了其电活性的差异。PANI内部颗粒状紧密层和外部蓬松网状疏松层的结构显著增大了膜的比表面积，相比PPy具有更好的电催化活性和更高的电池效率。Nanostructured polyaniline （PANI） and polypyrrole （PPy） electodes were prepared on FTO conductive glass surface in acidic aqueous solution by simple electropolymerization method. The morphology and electrochemical activity of two polymer films were investigated using scanning electron microscope （SEM） and cyclic vohammetry method. The results indicates that the differences of two polymer morphology results in the differences of electrical activity. Polyaniline films with compact layers and scattered layers has high surface area, which leads to a better electrical activity and energy conversion efficiency than PPy film.
