The authors present the first reported use of vertically oriented titanium oxide nanotube/polypyrrole (PPy) nanocomposites to increase the specific capacitance of TiO2 based energy storage devices. To increase their electrical storage capacity, titanium oxide nanotubes were coated with PPy and their morphologies were characterized. The incorporation of PPy increased the specific capacitance of the titanium oxide nanotube based supercapacitor system, due to their increased surface area and additional pseudo-capacitance.
作者首次报道了使用垂直取向的二氧化钛纳米管/聚吡咯（PPy）纳米复合材料来提高基于TiO₂的储能器件的比电容。为了提高其电存储容量，对二氧化钛纳米管进行了PPy涂层处理，并对其形态进行了表征。由于表面积增加和额外的赝电容，PPy的加入提高了基于二氧化钛纳米管的超级电容器系统的比电容。
