本論文係有關氧化銫鎢/還原氧化石墨烯/聚二氧乙基噻吩:聚苯乙烯磺酸(CsxWO3/rGO/PEDOT:PSS)奈米複合物之製備及其在可撓式全固態透明超級電容器之應用。首先以一步溶熱法於200ºC反應20小時製備出CsxWO3/ rGO新穎奈米複合材料，結果顯示，藉由rGO作為基材可有效地避免CsxWO3聚集。接著將上述粉體與PEDOT:PSS-EG溶液混合形成良好之分散液，PEDOT:PSS經EG修飾後因屏蔽效應使結構重排為線性結構，電化學特性大幅提升。再者將CsxWO3/rGO/PEDOT:PSS-EG分散液以滴鑄法塗佈於碳紙上作為電極，於固定PEDOT比例下，觀察CsxWO3之循環伏安圖形具一對氧化還原峰，證實其贋電容特性。為了符合透明、可撓之目標，亦將分散液以刮刀法塗佈於ITO上作為可撓式透明電極，藉由面電阻、透光性、電容特性分析找出最適化塗佈層數。最後成功地以聚乙烯醇/硫酸(PVA/H2SO4)作為膠態電解質，並與兩片電極組裝成對稱型可撓式全固態透明超級電容器，其於電流密度0.05 mA/cm2下之比電容值為1.79 mF/cm2，其電化學性能於彎折時皆可保留，經3000個循環後仍有約98%之初始電容值，具有發展為可撓式全固態透明超級電容器之潛力。

This thesis concerns the fabrication of flexible all-solid-state transparent supercapacitors with CsxWO3/rGO/PEDOT:PSS. Firstly, CsxWO3 nanorods-decorated reduced graphene oxide (CsxWO3/rGO) has been successfully synthesized via a facile one-step solvothermal reaction at 200ºC for 20 h. It was shown that the use of rGO as a support could effectively avoid the aggregation of CsxWO3 nanorods. Secondly, CsxWO3/rGO was added to PEDOT:PSS and EG to yield homogeneous dispersion. The EG treatment screened the ionic interaction between PEDOT and PSS, and the chains structure was reoriented linearly, which could enhanced the electrochemical performance. Then, CsxWO3/rGO/PEDOT:PSS-EG dispersion was drop-casted on carbon paper as electrode, the pseudo-capacitance characteristics of CsxWO3 was observed with a pair of redox peaks at a fixed PEDOT:PSS ratio. Thirdly, CsxWO3/rGO/PEDOT:PSS dispersion was blade-coated on ITO as flexible transparent electrode, and the optimum coating layer was obtained through sheet resistance, transmittance and capacitance analysis. Furthermore, symmetric flexible all-solid-state transparent supercapacitors were fabricated with the integration of two electrodes and PVA/H2SO4 gel electrolyte. The result revealed that CsxWO3/rGO/PEDOT:PSS-EG supercapacitor had 1.79 mF/cm2 capacitance at a current density of 0.05 mA/cm2 and 98% capacitance retained after 3000 cycles, which demonstrated that CsxWO3/rGO/PEDOT:PSS-EG had great potential applications in the field of flexible all-solid-state transparent supercapacitors.
