- •
Ionic liquids [BMIM]BF4, [BMIM]PF6 and conventional electrolyte TBAP were utilized for the fabrication of polymer films and EC devices.
- •
The improved ionic conductivity with the introduction of ionic liquid leads to ions more easily dope into the polymer film.
- •
The thickness of polymer film plays the critical role for the EC switching speed.
- •
The size of doping anion has essential influence on the electrochemical stability.
