Fig. 1

a Structure change of the SiO2/PCb-PEG-EG ERPC (30/60/5/5 vol%) as it was switched between the colored state and the colorless state by an electric field; b, c SEM images, and d, e the reflection (red plots) and the transmission spectra (blue plots) for the ERPC in the colored state and the colorless state; f time evolution of the structural colors and g, h the reflection spectra during a complete circle of color switching.
