Effect of Concentration of Electrolyte Solution on the Electrochemical Stability of Ionogel

Ionogel is an emerging hybrid material where the ionic liquid is immobilized within polymer matrix. Interesting combination of properties has permitted wide applications of ionogel. In this study, a well-known method, sol-gel is used to synthesize ionogel. However, it is intended to identify the optimum concentration of ionic liquid within ionogel which endows the ionogel with the best electrochemical performance. By varying the concentration of ionic liquid, the appearance of ionogel is compared. FTIR is performed to understand the structural changes that occur in ionogel. Linear Sweep Voltammetry is performed to study the electrochemical stability of ionogel.
