“…Next, we examined the mechanical properties of the pure RC, PEDOT/RC-SPP, and PEDOT/RC-VPP fibers with tensile tests. The RC fiber has already been demonstrated to have an excellent mechanical performance, compared to those of other polymer fibers. − As shown in Figure A,B, the PEDOT layers coated onto the surface of the RC fibers did not cause a significant decrease in the mechanical strength of the RC fibers. The tensile strength of PEDOT/RC-VPP (181 ± 8.2 MPa) was practically similar to that of PEDOT/RC-SPP (178 ± 10.1 MPa).…”

Green electronics based on biodegradable polymers have received considerable attention as a solution to electronic waste (e-waste). Herein, we describe an efficient approach to constructing green conductive fibers, comprising poly(3,4-ethylenedioxythiophene) (PEDOT) and regenerated cellulose (RC), via a wet-spinning process and vapor-phase polymerization (VPP). Eco-friendly RC fibers were prepared as a support layer by wet spinning, and the conductive PEDOT layers were coated onto the surface of the RC fibers by the oxidation of EDOT monomers. We demonstrated that the vapor-phase-polymerized PEDOT/RC composite fibers (PEDOT/RC-VPP) exhibited approximately 17 times higher electrical conductivity (198.2 ± 7.3 S/cm), compared with that of the solution-phase-polymerized PEDOT/RC composite fibers (PEDOT/RC-SPP, 11.6 ± 0.6 S/cm). Importantly, PEDOT/RC-VPP exhibited a high tensile strength of 181 MPa, good flexibility, and long-standing electrical stability under ambient air conditions. Moreover, the obtained PEDOT/RC-VPP under 50% strain turned on a green light-emitting diode (LED), indicating the flexibility and stability of green conductive fibers. This strategy can be easily integrated into various electronic textiles for the development of next-generation wearable green electronics.

“…The peaks of symmetric (1430 cm –1 ) and asymmetric C α C β stretching vibration (1510 cm –1 ) in PEDOT-0.8/rGO film are more intense than those in the PEDOT-0.8/GO film, demonstrating that more exposed PEDOT nanofibrils in the expanded rGO foam are easily detected by Raman spectroscopy. Besides, two weak peaks at 570 and 988 cm –1 are also observed in the PEDOT-0.8/rGO films, which are associated with the deformation of the oxyethylene rings in PEDOT polymer . The survey XPS spectrum of PEDOT-0.8/rGO displays substantially reduced oxygen level (Figure h), and the C 1s spectrum shows much less C–O and CO groups as compared to the PEDOT-0.8/GO (Figure i).…”

“…In addition, a pair of redox peaks at the oxidation potential of 0.5 V and reduction potential of 0.3 V (vs Ag/AgCl) are clearly observed for PEDOT-0.8/rGO films. Considering that the pseudocapacitive PEDOT does not exhibit obvious redox peaks, , the redox peaks in Figure a may originate from the Faradaic reactions between the electrolyte and oxygen surface functional groups of rGO sheets. The enhanced specific capacitance of the PEDOT/rGO films is evidenced from its longer charge and discharge times than the PEDOT/GO films (Figure b).…”

Suppressing sheets stacking of graphene oxide (GO) films by introducing conductive polymers proves to be an effective way to develop graphene-based electrodes for electrochemical energy storage. This work reports a facile a method for the preparation of poly(3,4-ethylenedioxythiophene)/GO (PEDOT/ GO) hybrid films by incorporating poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) between GO sheets. The subsequent dissolution of partial PSS substantially promotes the ion diffusion kinetics and simultaneously enhances film conductivity up to 931 S m −1 . It has a specific capacitance of 210 F g −1 and retains 98% of its capacitance after 10 000 cycles. Further reduction of PEDOT/GO film in hydrazine vapor converts GO to chemically reduced graphene oxides (rGO) and simultaneously expands the compact film into a foam-like structure. Due to more opened electrochemically active sites and favorable ion pathways, the enhanced capacitive performance including larger specific performances of 257 F g −1 , higher rate capability of 54% in 0.2−10 A g −1 , and superior cycling stability with 97% capacitance preservation over 10 000 cycles has been achieved for the PEDOT/rGO film. An all-solid-state capacitor assembled with PEDOT/rGO films also demonstrates good capacitive performance and satisfactory flexibility at large bending angles.

“…The quality of conductive polymers, as a matrix of TEs, largely determines the performance of their composites. One-dimensional conductive polymers possess relatively high conductivity, environmental stability, better dispersity, a short diffusion path, etc., which is hot research when applied to sensors, painting, and flexible devices [ 50 , 51 ]. This part will be unfolded based on different conductive polymers.…”

Stretchable wireless power is in increasingly high demand in fields such as smart devices, flexible robots, and electronic skins. Thermoelectric devices are able to convert heat into electricity due to the Seebeck effect, making them promising candidates for wearable electronics. Therefore, high-performance conductive polymer-based composites are urgently required for flexible wearable thermoelectric devices for the utilization of low-grade thermal energy. In this review, mechanisms and optimization strategies for polymer-based thermoelectric composites containing fillers of different architectures will be introduced, and recent advances in the development of such thermoelectric composites containing 0- to 3-dimensional filler components will be presented and outlooked.
