顺序加料法制备聚苯胺与聚吡咯复合物及其电化学电容性能

Sequence Feeding Preparation and Supercpacitive Performence of Polypyrrole and Polyaniline Composite

以顺序加料原位聚合法化学氧化制备了聚吡咯(PPy)和聚苯胺(PANi)的复合物。采用SEM、红外光谱表征其结构,采用电化学工作站测试其超级电容性能。结果表明:制得的聚苯胺与聚吡咯的复合物,形成了二次结构;复合物的循环伏安特性曲线均接近于理想的矩形,恒流充放电曲线基本为线性,呈现双电层电容;PANi-PPy和PPy-PANi复合物的最高比电容分别达到227.6、195.5 F/g。

The composite of polypyrrole （PPy） and polyaniline（PANi） was successfully sythesized by in situ sequence feeding chemical polymerization. The composite was characterized by scanning electron microscopy, filter-grating infrared spectrometer for structure, and electrochemical station for supercapacitive performance. Results show that the composite of polypyrrole and polyaniline have hierarchy structure; the cyclic voltammetry curves of the composite approach the rectangular-like; the typical constant discharge responses are found; the excellent supercapacitive performance present electric double-layer capaci- tance. The maximum specific capacitance of PANi-PPy respectively. and PPy-PANi reaches 227. 6 and 195. 5 F/g,
