為了提高水凝膠高分子電解質的離子導電性和機械性能，本研究針對離子導電度實施了一系列三成分混合物實驗設計，包括共聚物系統、混摻添加物的共聚物和混摻雙電性離子修飾之添加物的共聚物系統。
首先，測量了以Polyethylene glycol diacrylate (PEGDA) 交聯，混合甲基丙烯酸硫代甜菜鹼 (SBMA) 、[2- (Methacryloyloxy) ethyl] trimethylammonium (META) 和2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPS) 之共聚物系統的離子導電度，輔以機械性能的評估，決定了最適點SMA，其離子導電度為49.5 mS cm–1。接著，合成了三種添加物，球狀的SiO2、平面層狀的GO (氧化石墨烯) 和棒狀的HA (羥基磷灰石)，以及經雙電性離子修飾之添加物 (zSi、zGO、zHA)，在經FT-IR、XRD、NMR、TGA、SEM鑑定後，作為添加物分別與SMA共聚物主體混合。在第二個實驗設計中，最適點aSMA之離子導電度為66.1 mS cm–1，破裂應力和應變為0.2 MPa和79.5%。在第三個實驗設計中，最適點zaSMA之離子導電度為71.5 mS cm–1，破裂應力和應變為0.245 MPa和77%。
zaSMA在動態機械分析 (DMA) 中表現了最佳的彈性，亦在對稱式活性碳超級電容器中表現出最佳的電化學性能，在0.5 A g–1時具有超過140 F g–1的比電容，在功率密度為5211.87 W kg–1時具有18.73 Wh kg–1的能量密度。在循環壽命測試中，2 A g–1的電流密度下，經過5000圈定電流充放電循環後，電容保存率為95.6%。顯示其優異的性能以及混合物實驗設計方法之有效性。

To optimize the ionic conductivity and mechanical properties of hydrogel electrolytes, this study gave a series of three-component mixture design experiments on ionic conductivity of the copolymer system, copolymer host with additives and copolymer host with zwitterionic additives. In the first mixture design, the ionic conductivity of PEGDA crosslinked copolymer system containig sulfobetaine methacrylate (SBMA) , [2- (Methacryloyloxy) ethyl]trimethylammonium (META) , and 2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPS) was measured, along with analyses of mechanical properties, an optimal point was determined and named SMA, with an ionic conductivity of 49.5 mS cm–1. Next, additives including spherical SiO2, planar graphene oxide (GO) , rod-shaped hydroxyapatite (HA) and their zwitterion-grafted versions (zSi, zGO, and zHA) being synthesized and characterized by FT-IR, XRD, TGA, NMR, SEM were mixed with SMA polymer host in the second and third mixture design respectively. In the second mixture design, an optimal point was determined and named aSMA with an ionic conductivity of 66.1 mS cm–1, breakout stress and strain of 0.2 MPa and 79.5%. In the third one, the optimal point, zaSMA, had ionic conductivity of 71.5 mS cm–1 ,breakout stress and strain of 0.245 MPa and 77%. zaSMA showed the best elasticity in dynamic mechanical analysis (DMA) and exhibited the best electrochemical performance with specific capacitance of over 140 F g–1 at 0.5 A g–1 and energy density of 18.73Wh kg–1 at power density of 5211.87 W kg–1 in carbon-symmetry supercapacitor. In cyclic life testing, zaSMA maintained a capacitance retention of 95.6% after 5000 cycles of galvanostatic charge/discharge at a current density of 2 A g–1.
