本論文首先以蘋果果膠分散之多壁奈米碳管(Multi-walled carbon nanotubes, MWCNTs) 懸浮液滴覆在紙張表面形成導電紙，由穿透式電子顯微鏡分析發現蘋果果膠對於奈米碳管具有良好的分散效果。奈米碳管懸浮液經由纖維的毛細作用將奈米碳管吸附於紙張表層，使導電層與紙基板之間產生良好的附著。導電紙經過多次彎曲後其電阻值相當穩定，表示紙張纖維對於滲入之奈米碳管有良好的錨定作用和良好的可撓曲性及導電性。將PVA/H3PO4固態電解質置於導電紙電極中，熱壓封裝成三明治式紙基超級電容器，透過循環伏安儀對其進行電化學分析，發現它不僅具有良好的電容行為與循環穩定性，且比電容值明顯優於其他文獻所製的超級電容器。

In this study, multi-walled carbon nanotubes (MWCNTs) were dispersed with pectin ultrasonic homogenizer under solution first. Carbon nanotubes suspension was prepared by using centrifuge to eliminate the impurities. Second, dispersed MWCNTs suspension was dropped on the shallow surface of commercial copy paper, but not completely penetrated through the whole thickness of paper. A paper-based conductive paper was formed after dried, and was used as electrodes. The electrical conductivity and surface morphology of the paper-based conductive paper were examined by four probe and atomic force microscope. Solid state electrolyte was prepared by casting the mixture solution of phosphoric acid and polyvinyl alcohol on glass plate. The paper-based supercapacitor was constructed by one solid state electrolyte inserted between two electrodes, which were assembled into a sandwich structure by hot press. The specific capacitance and cycle stability of the paper-based supercapacitor was investigated by cyclic voltammetry analyzer.
