将聚吡咯(PPy)/碳纳米管(CNT)复合电极制备在陶瓷织物上，用于电化学电容器。用化学气相沉积(CVD)方法在陶瓷织物上生长碳纳米管，然后用化学聚合的方法在其上涂覆聚吡咯(PPy)。碳纳米管在多孔陶瓷织物上具有较大的比表面积和较高的导电性，提高了其储能能力。聚吡咯不仅作为活性材料提供了额外的电容，而且还增强了碳纳米管与陶瓷织物之间的粘附性。此外，PPy作为导电粘合剂连接每个单独的碳纳米管，以增加电容。用扫描电子显微镜和透射电子显微镜证实了聚吡咯-碳纳米管在陶瓷织物上的形貌，并通过循环伏安和恒流充放电测试研究了其电化学性能。(C)2011爱思唯尔有限公司。保留所有权利。
Polypyrrole (PPy)/carbon nanotube (CNT) composite electrodes are fabricated on ceramic fabrics for electrochemical capacitor applications. The CNTs are grown on the ceramic fabrics by the chemical vapor deposition (CVD) method and PPy is subsequently coated on them by chemical polymerization. The large surface area and high conductivity of the CNTs on the porous ceramic fabrics enhance their energy storage capacity. PPy provides not only additional capacitance as an active material, but also enhances the adhesion between the CNTs and ceramic fabrics. Furthermore, PPy acts as a conducting binder for connecting every individual CNT to increase the capacitance. The morphology of the PPy-CNTs on the ceramic fabrics is confirmed by SEM and TEM, and the electrochemical characteristics are investigated by cyclic voltammetry and galvanostatic charge-discharge tests.
