15.3.5 Electrical properties of IL/PVDF-HFP/PEDOT:PSS/xylitol

An IL/PVDF-HFP/PEDOT:PSS/xylitol composite was fabricated by sandwiching a thin film
of IL/PVDF-HFP between two PEDOT:PSS/xylitol films. Using the 4-point probe method,
the conductivity of PEDOT:PSS/xylitol film can be derived to be 73.5 S/cm. Using the
same method, the resistance of IL/PVDF-HFP with 20 and 30 wt.% IL was measured to be
25.9 and 0.27 MΩ, respectively.
