### Electrochemical Impedance Spectroscopy (EIS)  
The impedance spectra obtained by Electrochemical Impedance Spectroscopy were plotted as a Nyquist diagram and modeled by equivalent circuits. Figure 11A shows the equivalent circuit for the impedance spectrum of the B1 and B16 samples. This circuit comprises a load Q1 in series, with a load transfer resistance R1, followed by load transfer resistance R2 in parallel with load Q2. This behavior is associated with the ability to transfer load. Figure 8: FTIR analysis of the samples B1 PVA-Chi, B2 PVA-Chi/PPy0.1, B3 PVA-Chi/PPy0.2, B4 PVA-Chi/PPy0.3. This circuit comprises two load transfer resistances R1 and R2 in series followed by a capacitance C2. It can be seen in Figure 12A that there is a small decrease in the intersection with the semicircle, followed by a line; this effect is due to the transfer of electrons, while the line may be due to the limited diffusion process. In Figure 12B, it is possible to see a Bode diagram of magnitude (\(\mid\!Z\!\mid\)) and frequency (Hz); the magnitude starts at approximately \(4\times 10^{6}\) ohm at low frequencies, while at high frequencies the magnitude decreases to \(5\times 10^{5}\) ohm. Regarding the phase angle, an angle close to \(-10^{\circ}\) can be observed at the beginning in the low frequency region; the phase angle then decreases until reaching \(-80^{\circ}\). This is because PVA reduces resistive behavior, which results in the predominance of capacitive behavior. Figure 12B shows the presence of a semicircle but at a lower frequency, indicating a transfer of electrons. This is followed by a line that could indicate energy release, since the molecular structure of PPy has double bonds (C=C) alternating with C-C bonds, forming conjugated structures along the chain that allow the transfer of electrons. Figure 9: FTIR analysis of the samples B1 PVA-Chi, B5 PVA-Chi/PEDOT: PSS0.1, B6 PVA-Chi/PEDOT: PSS0.2, B7 PVA-Chi/MWCNT0.1, B8 PVA-Chi/MWCNT0.2, B9 PVA-Chi/CB0.1 and B10 PVA-Chi/CB0.2. Figure 13 shows the diagrams for the B11 sample. Compared with the PVA-Chi/PPy0.1/ PEDOT: PSS0.1/MWCNT0.1/CB0.1 sample. The Nyquist diagram in 13 shows a semicircle indicating load transfer, followed by a pseudo-line indicating energy release. The Bode diagram of magnitude (1 Z1) and frequency (Hz) in 12 (B) shows an initial magnitude of 4 \(\times\) 10\({}^{4}\) ohm that decreases to 0 ohm and then remains constant. At lower frequencies, the phase angle remains constant at \(-\)85\({}^{\circ}\) but increases up to 10\({}^{\circ}\) at high frequencies it. The sample has a resistive behavior due to the presence of amino groups in the molecular structure of Cs and PPy, which generate a positive charge. PEDOT also contributes to the resistive behavior; it is considered an electroactive polymer due to the presence of interlocking polymer chains that allow the passage of cathodic charges.

Figure 11: Equivalent circuit (**A**) R1/(Q1+Q2/R2) and (**B**) Equivalent circuit R1/(R2 + C2). They analyzed the electrical conductivity of the materials as a function of frequency. They recorded the maximum conductivity in the B11 PVA-CS/PPy0.3/PEDOT:PSS0.2/MW CNT0.2 sample, with approximately 6E6 Hz and 562 S/m. The samples B1 PVA-CS/PPy0.3, B2 PVA-CS/PPy0.2, B3 PVA-CS/PPy0.1, B4 PVA-CS/PEDOT:PSS0.2, B5 PVA-Cs/PEDOT:PS0.1, B11 PVA-CS/PPy0.3/PEDOT:PSS0.2/MWCNT0.2, B13 PVA-CS/PPy0.2/PEDOT:PSS0.1//MWCNT0.1//CB0.1 showed a phenomenon in which PPy and PEDOT:PPS, mainly because they have higher affinity between them, and this led to a greater dispersion of energy to nearby frequency 6E6 Hz, and to functional groups such as -OH.
