Figure 3

Characteristics of the ion gel (40% polymer content). (a) Impedance magnitude () versus frequency plots over a wide temperature range. (b) Capacitance versus frequency plots over a wide temperature range. (c) Conductivities of the ion gel over a wide temperature range. (d) Weight retention rate versus time plot of the ion gel stored in a large amount of water, demonstrating the water resisting property. Its weight showed almost no change all along the testing time, and the ion gel maintained its original shape. (e) Weight retention rate versus time plot of the several kinds of ionic conductors stored at different relative humidities (RH), demonstrating the humidity stability of the ion gel. Testing temperature was 25°C. Blue area represents ; yellow area represents . (f) Photograph of the ionic conductors before (upper) and after storing at 40% RH for 24 hours. (g) Photograph of the ionic conductors before (upper) and after storing at 85% RH for 24 hours. (h) Photograph of several kinds of ionic conductors before (upper) and after heating at 60°C for 2 h. (i) Photograph of the ionic conductors before (upper) and after storing at -20°C.
