本研究使用含聚乙二醇（PEG）的樹脂透過化學誘導相分離法製備水凝膠超級電容。使用聚乙二醇二丙烯酸酯（PEGDA）和聚乙二醇二缩水甘油醚（PEGDE），藉由調整環氧樹脂與溶劑的比例，探討不同水凝膠電解質的電解液吸收率、離子導電度(σ)與比電容值(Cs)。PEGDA製備水凝膠薄膜浸泡於1M H2SO4電解液，在30°C離子導電度為47 mS/cm，比電容值為123 F/g。PEGDE製備的水凝膠電解質在30°C離子導電度為117 mS/cm，比電容值為136 F/g。

Hydrogel-based supercapacitors were prepared using poly(ethylene glycol)-based resins, such as polyethylene glycol diacrylate (PEGDA) and poly(ethylene glycol) diglycidyl ether (PEGDE), through a chemically induced phase separation method. By adjusting the ratio of resin to solvent, the study investigated the liquid electrolyte uptake, ionic conductivity (σ), and specific capacitance (Cs) of different hydrogel electrolytes. It was found that the hydrogel-based supercapacitors made from PEGDA film soaked in 1M H2SO4 exhibited an ionic conductivity of approximately 47 mS/cm and a specific capacitance of 123 F/g at 30°C. For the PEGDE-based hydrogels, the ionic conductivity reached approximately 117 mS/cm, and the specific capacitance increased to 136 F/g at 30°C.
