Preparation of 3-layer actuators containing CNT-s, EMIBF4, PVDF-HFP

Preparation of actuator electrode layers:

  • CNT(ID-PO356) 50.04 mg
  • EMIBF4 (Aldrich) 124.5 mg
  • PVDF-HFP (Kynar 2801) 50.1 mg
  • DMAc ~(4 mL + 5 mL)


The electrode layer was fabricated by casting 1.6 ml of the electrolyte solution in the Teflon mold (an area of 2.5cm×2.5cm)
and evaporating the solvent, perfectly. The thickness of the obtained electrode film was 50–60mkm.


Preparation of actuator electrode layers:

  • EMIBF4 (Aldrich) 202 mg
  • PVDF-HFP (Kynar 2801) 204,3 mg
  • PC 497 mg
  • MP 2 mL


The gel electrolyte layers were fabricated by casting 0.3 ml of the solution to the Tefon mold (an area of 2.5cm×2.5 cm) and evaporating the solvent perfectly. The thickness of the obtained gel electrolyte film was 15-18 mkm. An actuator film was fabricated by hot-pressing the electrode and electrolyte layers which have the same internal IL. The thickness of the actuator film was 100-110mkm, which are smaller than the sum of those of two electrode and one electrolyte layers, since the thickness of each layer decreases by being hotpressed
