本研究試圖開發以多壁奈米碳管紙為電極之超級電容，並利用多種方式提升其性能。在電極方面以鹽活化和氮摻雜熱處理的方式處理奈米碳管，製作出具有高比表面積和電性的碳管紙；在電解質方面，選擇使用高濃度醋酸鉀為電解質(water in solute, WIS)，可提供較高的工作電壓，以濾紙作為分隔層去吸滿電解質後封裝成三明治超級電容。由循環伏安法二極式測得的比電容為 13 F/g，相較於未處理的碳管紙超級電容，其比電容可以提升1.67倍。此外經過 3000 次循環伏安法測試後，仍保有 94 %的優異比電容維持率。最後搭配多層堆疊的組合方式組裝超級電容，可再次提升電壓和電容。
最後將封裝好後的超級電容作串聯，將其充電十秒後再接至小馬達上，可以成功讓它運轉，可說明不需要耗費繁複的製程和高額的成本，也能製作出具有一定效能且輕、薄、可撓式超級電容。

This research attempts to develop flexible supercapacitors using composites made from modified multi-walled carbon nanotubes and paper fibers as electrodes. Various methods are employed to improve electrochemical performance of carbon nanotubes, including salt activation and nitrogen-doping, in conjunction with concentrated potassium acetate as electrolyte and filter paper as dielectric layers to promote working voltage. Composites are piled and packed into sandwiched structures and electrochemical measurements reveal retention and specific capacitance to be 94% over 3000 cycles and 13F/g; value which is a factor of 1.67 greater than untreated electrodes. Charging of supercapacitors connected in series for 10 s gives a sufficient power capable of driving electric motors. Supercapacitors made here display advantages including low cost production, processing with ease, flexible and eco-friendly.
