PEDOT is a conductive polymer with a conjugated structure, which has great steric hindrance and ion exchange capacity, but its compatibility is poor. Herein, a novel PEDOT-hydroxypropyl-β-cyclodextrin (P-CD) inclusion complex was synthesized and was used as an additive for anticorrosive epoxy coating. UV, FTIR, Raman and XRD spectra demonstrated that the HP-β-CD was successfully attached with the PEDOT and enhanced the solubility and dispersion of PEDOT. The epoxy coatings without and with a small content of P-CD (0.5 wt.%, 1 wt.%) were prepared and the anticorrosion properties were assessed by electrochemical impedance spectroscopy (EIS) and corrosion product analysis. The results indicate that the composite coating exhibits a higher impedance modulus compared to the pure epoxy coating. The main reason is the barrier performance of P-CD, which increases the diffusion path of corrosive media, and P-CD can enhance corrosion resistance by promoting the formation of Fe 3 O 4 passivation layer on the surface of steel.

A polyoxometalate (POM)-doped poly(3,4-ethylenedioxythiophene) (PEDOT) hybrid film counter electrode was successfully fabricated by electropolymerization in an environmentally friendly aqueous solution. The hybrid film presents a similar surface morphology to lotus leaf, the microstructure of which is a regularly distribution of mastoid shapes. As far as we know, it is the first time that POM-PEDOT hybrid film with mastoid morphology was fabricated. The application of the hybrid film counter electrodes (CEs) in dye-sensitized solar cells (DSSCs) was studied for the first time, and the efficiency of DSSCs based on hybrid film CEs was almost as high as DSSCs with Pt CEs. FTIR results indicated that POM polyanions had already been dispersed into the PEDOT matrix. Cyclic voltammetry, electrochemical impedance spectroscopy, and Tafel polarization test results show that the electrocatalytic ability for I3– reduction of the hybrid film CE is comparable to that of a Pt CE. In addition, the SiW11–PEDOT hybrid film has good electrochemical stability.

Poly(3,4-ethylenedioxythiophene) (PEDOT) coating is advantageous in constructing flexible sensors, due to its good flexibility, high conductivity, and excellent physical and chemical stability. Traditional solution-based coating methods, however, are difficult to retain the micro- and nanostructures of the substrates, thus decreasing the sensitivity of the resulted sensors. In this work, we prepared superhydrophobic (SHB) strain sensors using a piezoresistive composite made from consecutive vapor deposition of conformal polymer coatings , i.e. PEDOT and poly(perfluorodecyl acrylate- co -ethylene glycol diacrylate) on fabrics using oxidative and initiated chemical vapor deposition methods. Compared with the pristine fabric sample, the composite materials displayed significantly improved initial currents, which are attributed to more conductive paths created by PEDOT coating. The resulted strain sensor displayed great flexibility, large sensitivity, wide sensing range, and excellent reliability. Furthermore, the sensor has been successfully employed to monitor various human motions in real time. The hydrophobic outer layer endows the sensor self-cleaning and durability capacities, indicating possible applications under harsh environment.

Wearable electronics have attracted tremendous interest owing to their potential applications on rehabilitation training treating, and human health monitoring. Poly(3,4-ethylenedioxythiophene)@Cotton/spandex fabric (PEDOT@CSF) was developed for flexible, multifunctional, and smart healthcare textiles via high efficiency and environmentally friendly in situ enzymatic polymerization. PEDOT@CSF shows the good UV resistance, outstanding electrothermal heating, and excellent sensing performance. In detail, surface temperature rapidly reached to 130.6 °C for PEDOT@CSF, when the supply voltage at 10 V. The heater could carry out thermal therapy in any designated body part for patients. Meanwhile, the required temperature could easily be obtained by varying the supplied voltages. The motion of human joints (such as fingers, wrist, and elbow) and respiratory condition were recognize and monitor by PEDOT@CSF that easily attached to clothes and accessories. PEDOT:p-toluenesulfonic acid (PEDOT:TsOH) give the textiles a smart sensing ability with fast response, and excellent durability. Furthermore, electrical resistance of PEDOT@CSF exhibited better stability under heating conditions, long time storage, multiple bending, and washing cycles. In summary, we have developed an environment-friendly and general method and obtained a high-performance multifunctional conductive textile, which provide a new path for the green synthesis and improvement of conductive polymer-based materials and development of flexible thermotherapy.

Bioenzyme-catalyzed conductive polymer polymerization is an ecological and environmental protection method that aligns with the current sustainable development plan. Hence, a new strategy of in situ assembly of poly (3,4-ethylenedioxythiophene) (PEDOT) on the surface of fabrics via free radical polymerization initiated by the cascade reaction of glucose oxidase (GOx) and horseradish peroxidase (HRP) was introduced. With excellent photothermal conversion capability and sensitive humidity response, PEDOT endows the fabric with remarkable photothermal performance, humidity sensing performance, and UV resistance capability. It is worth noting that the PEDOT-coated fabric can reach a fantastic 54.2 °C within 20 s under 2 sun irradiation intensity and finally reach 98.4 °C. In addition, it can maintain stable and fast responses in repeated and long-term operations. Moreover, the PEDOT-coated fabric has a fast response and long-term working ability in high humidity. This work provides a new environmental protection and sustainability idea for designing and developing conductive polymer-based high-performance composites.

Flexible thermoelectric fabrics hold great promise for applications in smart wearable devices, particularly in areas such as self-powered sensing, energy harvesting, and human-machine interaction. However, with the rapid advancement of flexible electronics, higher standards are being set for the durability, integration, and multifunctionality of wearable electronics. Currently reported thermoelectric materials still struggle to meet these demanding requirements. In this study, a dual-catalytic polymerization strategy is proposed to fabricate PEDOT-based thermoelectric fabrics by synergizing enzymatic and chemical polymerization. Enzymatic polymerization contributes to forming dense conductive layers, while chemical polymerization enables rapid construction of a structural framework, resulting in PEDOT@Nylon fabrics with excellent electrical conductivity (90.91 S/m), good durability (stable performance after 3 h washing and 600 bending cycles), and stretchability. The thermoelectric fabric can serve as a self-powered temperature sensor for contact/non-contact hot-cold recognition and ambient temperature monitoring over a broad temperature range (ΔT ~ 40 K). Additionally, it functions as a strain sensor, capable of real-time and rapid monitoring of human motion signals by integrating a wireless transmission system (with a response time of ~0.16 s). This efficient (4 h) dual-catalytic polymerization strategy produces high-performance thermoelectric fabrics, promising for wearable devices, smart healthcare, human-computer interaction, and next-generation multifunctional fabrics.

In this paper, Pt-PEDOT/reduced graphene oxide (Pt-PEDOT/rGO) nanocomposites were facilely prepared by a simple and cost-effective one-pot method. The obtained nanocomposites were characterized and confirmed by scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectra . As expected, the Pt-PEDOT/rGO nanocomposites modified glassy carbon electrode (Pt-PEDOT/rGO/GCE) exhibited higher charge transfer efficiency and electrocatalytic activity to the oxidation of caffeic acid (CA) in comparison with the bare GCE, rGO and Pt-PEDOT modified electrodes (rGO/GCE and Pt-PEDOT/GCE). Furthermore, the Pt-PEDOT/rGO/GCE showed a wide linear range of 5.0 × 10 −9 to 5.0 × 10 −5 M with a low detection limit of 2.0 × 10 −9 M (S/N = 3) for the determination of CA. More experiments indicated that the Pt-PEDOT/rGO/GCE performed superior reproducibility, selectivity and long-term stability. Finally, the modified electrode was also applied to detect CA in green tea and black tea samples with promising recovery and application prospect.

PEDOT-coated WOx nanorodes (NRs) were prepared for the first time by simply stirring WOx nanowires (NWs) with 3,4-ethylenedioxythiophene (EDOT) in aqueous solution. A series of spectroscopic characterizations indicate that the polymerization of EDOT occurrs not only on the surface but also along the [010] planes of WOx NW, resulting in the truncation of long WOx NW to produce WOx@PEDOT NRs with abundant oxygen vacancies. Furthermore, WOx@PEDOT NRs were used to prepare a hole transport layer (HTL) in planar p–i–n perovskite solar cells (PeSCs). The WOx@PEDOT-based devices yielded a comparable average power conversion efficiency (PCE) of 12.89% with improved open-circuit voltage (VOC) and fill factor (FF) but lower short-circuit current density (JSC), as compared to the devices with conventional PEDOT:PSS (12.88%). The observed device performance is mainly attributed to the better perovskite texture on the WOx@PEDOT HTL, improved energy alignment, and suppressed charge recombination at the WOx@PEDOT/perovskite interface as well as lower charge conductivity of the WOx@PEDOT HTL. In addition, the PeSCs based on WOx@PEDOT-doped PEDOT:PSS showed remarkably improved PCEs up to 14.73%, which may be ascrible to the combined merit of WOx@PEDOT NRs and PEDOT:PSS. More impressively, benefiting from the inherent neutral nature of WOx@PEDOT NRs, WOx@PEDOT-based devices exhibited obviously improved stability compared to that with PEDOT:PSS HTL. These results thus demonstrate a path toward the development of new hybrid nanostructures for efficient and stable PeSCs.

In this paper, we study the role of carboxymethyl cellulose (CMC) as a template for helping poly(3,4-ethylenedioxythiophene) (PEDOT) uniformly disperse into polyacrylamide (PAAM) hydrogel scaffold. The presence of a large amount of hydrogen bonds and chain entanglements enabled excellent mechanical properties with great stretchability and resilience. With the optimum mass loading of PEDOT (9.75 mg/cm 2 ), a sandwiched configuration of flexible supercapacitor based on the CMC-PEDOT/PAAM hydrogel can deliver the highest specific capacitance of 269 mF/cm 2 , a maximum energy density of 23.93 μWh/cm 2 at a power density of 400 μW/cm 2 and remained 16.18 μWh/cm 2 at a power density of 3200 μW/cm 2 , as well as enhanced cycle stability with 88% retention after 5000 cycles. In addition, such device can withstand severely bending and compressing deformations and properly operate at extreme temperatures (−40 ∼ 90 °C) with excellent capacitance property. What’s more, the excellent conductivity of the CMC-PEDOT/PAAM hydrogel contributed to outstanding strain sensing performances. When the supercapacitor was used to power the hydrogel strain sensor, the obtained self-powered sensing system is capable of monitoring physiological signals accurately. The multifunctional performance of the CMC-PEDOT/PAAM hydrogel could be potentially used in flexible electronic devices.

Flexible electronics have demonstrated various strategies to enhance the sensory ability for tactile perception and wearable physiological monitoring. Fibrous microstructures have attracted much interest because of their excellent mechanical properties and fabricability. Herein, a structurally robust fibrous mat was first fabricated by electrospinning, followed by a sequential process of functionalization utilizing ultrasonication treatment and in situ polymerization growth. Electrospun polyurethane (PU) microfibers were anchored with multi-walled carbon nanotubes (MWCNTs) to form conductive paths along each fiber by a scalable ultrasonic cavitation treatment in an MWCNT suspension. After, a layer of poly(3,4-ethylene dioxythiophene) (PEDOT) was grown on the surface of PU fibers decorated with MWCNTs to enhance the conductive conjunctions of MWCNTs. Due to the superior electromechanical behaviors and mechanical reinforcement of PEDOT, the PEDOT/MWCNT@PU mat-based device exhibits a wide working range (0–70 kPa), high sensitivity (1.6 kPa −1 ), and good mechanical robustness (over 18,000 cycles). The PEDOT/MWCNT@PU mat-based sensor also demonstrates a good linear response to different temperature variations because of the thermoelectricity of the PEDOT/MWCNT composite. This novel strategy for the fabrication of multifunctional fibrous mats provides a promising opportunity for future applications for high-performance wearable devices.

In this study, bimetallic Pd–Au/PEDOT/graphene (Pd–Au/PEDOT/rGO) nanocomposites were facilely prepared in an aqueous medium by a one-pot method. In addition to the Pd–Au/PEDOT nanoparticles, dendritic bimetallic Pd–Au nanoclusters were also obtained in the composites, which were verified by transmission electron microscopy and element analysis mapping characterization. The morphology of the nanocomposites was greatly influenced by the molar ratio of the added metal salt precursors. X-ray photoelectron spectroscopy and X-ray diffraction analyses indicated the presence of synergism and electron exchange between the Pd–Au bimetallic nanostructures, which play an important role in the enhancement of the electrocatalytic activity of the composite toward the oxidation of caffeic acid (CA). Under optimized conditions, the Pd–Au/PEDOT/rGO modified glassy carbon electrode showed a wide linear range of 0.001–55 μM and a low detection limit of 0.37 nM (S/N = 3) for CA detection. These results provide valuable insight on the development of novel modified electrodes based on bimetallic graphene nanocomposites for high performance electrochemical sensors.

PEDOT-Ag/AgCl is a highly promising material with dual functions of hydrogen evolution reaction (HER) and supercapacitors. In this study, a simple low-temperature stirring and light irradiation method was used to synthesize PEDOT-Ag/AgCl on the surface. Then, PEDOT-Ag/AgCl was analyzed using X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. PEDOT-Ag/AgCl reacted in 1 M KOH alkaline electrolyte with an overpotential of 157 mV at 20 mA·cm−2and a Tafel slope of 66.95 mv·dec−1. Owing to the synergistic effect of PEDOT and Ag/AgCl, this material had a small resistance (1.7 Ω) and a large specific capacitance (978 F·g−1at current density of 0.5 A·g−1). The synthesis method can prepare nanostructured PEDOT with uniformly-distributed Ag nanoparticles and rod-shaped AgCl on the surface, which can be used as both HER electrocatalysts and supercapacitor electrodes.
