摘要
应用铝/氧化铝模板在不同的条件下电化学聚合制备聚吡咯(PPy)膜,利用扫描电镜(SEM)研究其表面形貌.结果表明,使用该模板可制得具有特殊形貌的PPy,PPy形成一种微触手结构,该结构在脱离模板后,仍可沿其原来的趋势继续生长.通过研究发现,聚合时间为1600s、聚合电位1.0V、单体浓度0.2mol/L时制备的PPy膜微触手结构数量多,具有较大的比表面积.
PPy film with special micro-tentacle morphology was prepared by electrochemical polymerization using Al/Al2O3 template as the working electrode under different conditions. Morphology was investigated by SEM and it revealed that the obtained special morphology continued to grow after separating from the Al/Al2O3 template. It was found that the optimal polymerization condition to get the micro-tentacle morphology was electropolymerization time of 1 600 s, potential of 1.0 V and Py concentration of 0. 2 mol/L.
