Summary: Flexible supercapacitors based on PEDOT:PSS have been extensively studied due to their high conductivity, high theoretical capacitance, and excellent flexibility. However, there is a need to summarize the scattered literature studies and provide guidance for future research. This review focuses on the recent progress of PEDOT:PSS-based flexible supercapacitors from the perspectives of fiber, film, and three-dimensional porous block, and discusses the challenges and outlook for their practical application.

Summary: Magnesium ion batteries (MIBs) are attractive as next-generation energy storage systems due to their high safety, capacity, low reduction potential, material abundance, and economic efficiency. However, developing reversible and fast MIB cathode materials is challenging due to slow ion diffusion and weak interactions. In this study, a V2O5/PEDOT (VOP) complex with charge transfer interaction and an expanded interlayer spacing of 19.02A was designed to enable reversible and fast Mg2+ ion storage. Water activation was found to enhance the kinetics. The VOP electrodes exhibited high specific and high-rate capacity, as well as long-term cyclic stability.

Summary: PEDOT:PSS is commonly used as a counter electrode in dye-sensitized solar cells (DSSC), while PEDOT:Carrageenan has been introduced as an electrolyte. This review provides an overview of the different roles of PEDOT:PSS and PEDOT:Carrageenan in DSSC. It also describes the synthesis process and characteristics of both materials. Overall, PEDOT:PSS functions as a counter electrode by transferring electrons back to the cell and accelerating redox reactions, while PEDOT:Carrageenan as an electrolyte does not effectively regenerate the dye sensitized at the oxidized state, resulting in a lower performance in DSSC.

Summary: In this study, a smart infrared rewritable and emissivity tunable polymer film based on PEDOT:PSS is proposed. The adjustment ability of thermal emission is achieved by regulating the mobile polaronic of PEDOT with redox agents, resulting in a modulation of infrared emission > 30%. The reversible property of PEDOT's conformation and molecular stacking order is also demonstrated, accompanied by the transformation between dication state and neutral state. Additionally, a technique for direct writing and erasing process in the infrared region is implemented using a simple redox treating process.

Summary: In this study, reduced graphene oxide/poly(3,4-ethylenedioxythiophene):poly(sodium styrene sulfonate) composite (rGO/PEDOT:PSS) was prepared through a facile hydrothermal reaction and applied to a symmetric supercapacitor. The optimized composite showed improved electrochemical performance with a specific capacitance 50% higher than pure rGO. It also exhibited excellent photothermal properties with a high photothermal conversion efficiency of 62.0% under 808 nm NIR light illumination. The photothermal effect enhanced the supercapacitor's performance, increasing its specific capacitance and energy density by 1.8 and 1.6 times, respectively, under a low illumination intensity of 0.18 W cm-2. This study provides new design ideas for next-generation flexible and wearable devices and expands the application of light energy.

Summary: In recent years, a novel PEDOT:PSS/n-Si planar heterojunction solar cell has been extensively studied. The addition of V2O5 particles changes the surface morphology of PEDOT:PSS films and promotes its superior ohmic contact with the Si interface. The incorporation of PEDOT:PSS with V2O5 particles improves the photoelectric conversion performance of Si-based solar cells, resulting in significantly enhanced fill factor, photoelectric conversion efficiency, open-circuit voltage, and short-circuit current density.

Summary: The demand for flexible electronic devices has increased due to the high interest in electronic textiles (e-textiles). This has led to a growing interest in flexible energy storage devices to power e-textiles. This study introduces the use of electrospray deposition (ESD) technique for depositing PEDOT:PSS on conductive carbon yarns, creating flexible electrodes with a high surface area. The optimized deposition conditions of PEDOT:PSS have been evaluated for its electrochemical performance in a 1D symmetric supercapacitor with a cellulose-based gel as an electrolyte and separator, showing high specific capacitance, excellent cyclability, and outstanding bending capability.

Summary: In this study, two types of MnO2 nanosheets were synthesized and characterized for their electrochemical performance in different electrolytes. It was found that the ultrathin MnO2-NS-N nanosheets exhibited superior capacitance in Na2SO4 electrolyte, while the thick MnO2-NS-K nanosheets showed reasonable performance in both Na2SO4 and MgSO4 electrolytes. Surface capacitance played a significant role in the capacitive behavior of the MnO2 nanosheets.

Summary: The stretchability of PEDOT:PSS electrodes is influenced by two additives, PEG and GOPS. PEG forms hydrogen bonds with the sulfonyl groups of PSS, relieving mechanical stress in the PEDOT:PSS films. On the other hand, GOPS not only forms hydrogen bonds with PSS but also undergoes a chemical reaction to create a cross-linked structure, enhancing the stretchability of the PEDOT:PSS film. Additionally, GOPS promotes a more hydrophilic surface and improves adhesion to the upper layer in IS-OPV devices, resulting in improved stretchability and solar cell performance.

Summary: In this study, conductive SF-PEDOT:PSS hydrogel modified by plasma was successfully prepared by injecting cold plasma into the silk fibroin (SF) solution and adding poly (3,4-ethylenedioxythiophene): polystyrene sulfonic acid (PEDOT:PSS) into the SF solution. The effects of plasma discharge time and working gas type on the electrochemical parameters and structure of SF-PEDOT:PSS hydrogels were investigated. The results showed that argon and helium plasma reduced the impedance and increased the capacitance of the hydrogel, while air plasma had little effect on the impedance and reduced the capacitance of the hydrogel.

Summary: Metal oxide nanomaterials with grain sizes approaching or less than the Debye length show promise as highly sensitive gas sensors due to their large surface-to-volume ratio. This study focuses on the cost-effective synthesis of NiO nanoparticles for gas sensing applications. The results show that co-precipitated NiO nanoparticles exhibit higher sensitivity attributed to the abundance of adsorption sites brought about by the smaller grain size.

Summary: Magnetic properties of Y0.67Sr0.33MnO3 (YSMO) and La0.67Sr0.33MnO3 (LSMO) thin films heterostructures (YSMO/LSMO) on different substrates were investigated. The results showed that the heterostructures on LAO substrate exhibited an exchange bias effect of about 80 Oe, while those on STO substrates did not. The different strain conditions in LSMO films on LAO and STO substrates are suggested to contribute to the emergence of different magnetic ground states, leading to the significant exchange bias effect on LAO substrate.
