Carbon Nanofiber can act as a supercapacitor, facilitating paper based electronics.

To explore this further, we fabricated a supercapacitor using CNT, CNF, and manganese oxides. We then characterized their electrochemical properties in a three electrode system. A procedure modeled after a previous experiment was used (http://www.citeulike.org/article/8188780).

CNT (fabricated from previous experiments) was added to CNF. MnO2 was then electrochemically deposited onto the paper. It was calculated that 4.5 mg of MnO2 was deposited on to the paper and the specific capacitance of the paper was 410 F/g. Pictures of the experiment are shown below:

Owing to high capacitance, flexibility, robustness, low cost, and low environmental impact, MnO2/CNF-CNT paper supercapacitors can have great potential for diverse flexible energy storage applications.
