(a) Typical Nyquist plot in the p-dopable region and its equivalent circuit. R1=10.53 Ω, R2=8.51 Ω, TCPE1=437.16 μF, and α=0.91. (b) Potential value at the quasi-equilibrium state for the EIS measurement in the p-dopable region. (c) Typical Nyquist plot in the n-dopable region and its equivalent circuit. R3=4.82 Ω, R4=3.15 Ω, TCPE2=154.13 μF, and α=0.92. (d) Potential value at the quasi-equilibrium state for the EIS measurement in the n-dopable region. (e) RSMs for the ClO4− doped BPOE (indicated as I), 1 M NaClO4 in PC (indicated as II), and PC (indicated as III). (f) FT-IR measurements for I, II and III. (a.u. refers to arbitrary unit).
