(a) Schematic illustration of the electrochromic device assembled with the PS-b-PMMA-b-PS based ionogel. Photographs of the ionogel incorporated device after bending in the (b) bleached state and (c) colored state. (d) Symmetric square wave profile and corresponding transmittance at a wavelength of 550 nm against time. (e) Change in the transmittance of electrochromic device as a function of the operation time.
