The electronic properties of TR-CP were investigated above and below the LCST using electrochemical impedance spectroscopy (EIS) (Fig. ). For the PEDOT:PSS96-b-PNIPAM440 TR-CP, upon increasing temperature, the Bode plot showed a decrease in the impedance magnitude indicative of an increase in conductivity upon gelation (Fig. ). To confirm this result, a modified Debye circuit model (Fig. ), commonly used for PEDOT:PSS-based hydrogels was used to extract the electronic (Re) and ionic (Ri) resistances (Fig. ). Ri for the liquid (86.8 Ω) and gel (121.7 Ω) were found to be similar. However, Re decreased from 41.1 kΩ (liquid) to 22.5 kΩ (gel) on increasing temperature (Table ). Next, we studied the effect of the PEDOT loading on the electronic properties of the TR-CP (Fig. ) to optimize for low impedance. The PSS:PEDOT molar ratio was changed to 3.5:1, 2.2:1 or 1.75:1 by changing the loading of EDOT during the oxidative polymerization. PSS:PEDOT = 3.5:1 was chosen as the lower limit, as decreasing the loading of EDOT further only resulted in a slight increase in viscosity above the LCST, not gelation. At ratios higher than 1.75:1, the dispersions were not homogeneous at room temperature. We found that the 3.5:1 ratio showed the lowest impedance (Fig. ). From the equivalent circuit model (Fig. ), the ionic (𝜎 𝑖 ) and electronic conductivity (𝜎 𝑒 ) were calculated to be 34 mS cm -1 and 0.05 mS cm -1 , respectively (Fig. ). The TR-CP gel was incorporated into an electric circuit by depositing a liquid drop on a glass slide heated to 37 °C, demonstrating its ability to close a simple LED circuit upon gelation (Fig ). Lastly, we varied the concentration of the TR-CP thereby optimized with a PSS:PNIPAM:PEDOT ratio of 3.5:16:1, by reconstituting the lyophilized TR-CP in a phosphate-buffered saline (PBS) solution at different concentrations(Fig. ). As the concentration was increased from 3.6 wt% to 5.6 wt%, the 2-point probe DC conductivity increased from 2.1 mS cm -1 to 7.1 mS cm -1 . At 7.6 wt%, at which concentration the solution was very viscous and heterogeneous, the conductivity decreased to 5.5 mS cm -1 . The Nyquist plots for 3.6 wt% (Fig. ) and 5.6 wt% (Fig. ) displayed a smooth semi-circle, indicating good dispersion and homogeneity of the gel, while that of the 7.6 wt% TR-CP had irregular signals (Fig. ), further confirming that the gel was heterogenous leading to poor contact with the electrode. The fitting values of all circuit elements are tabulated in Table and calculated electronic and ionic conductivities are reported in Table . The highest conductivity recorded was for 5.6 wt% TR-CP (PSS:PNIPAM:PEDOT ratio of 3.5:16:1) in PBS: 𝜎 𝑖 = 200 mS cm -1 and 𝜎 𝑒 = 14 mS cm -1 from EIS (Fig. ) and σ = 10.4 mS cm -1 from 2-point probe, which is on par with other previously reported conductive hydrogels and sufficient for bioelectronic interfaces. Finally, the reversibility of the electronic properties of this TR-CP formulation was evaluated by repetitively (10×) cycling the temperature between 50 ºC (gel) and 20 ºC (solution) while monitoring the electrical resistance.
