Flexible electronic fabrics have garnered significant attention for their promising prospects in next-generation wearable electronic devices. However, fabricating flexible fabrics that simultaneously possess high conductivity, mechanical adaptability, energy conversion/storage，portability and comfort remains a critical challenge. Herein, multifunctional PEDOT: PSS/[BMIM]HSO 4 fibers were continuously fabricated via a wet-spinning technique using a green and cost-effective coagulation bath composed of DI water and 0.05 M 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIM]HSO 4 ). The fibers exhibited high conductivity (772.6 S· cm −1 ), favorable mechanical flexibility (elongation at break: 40.8% with Young's modulus of 107.1 MPa), along with excellent antibacterial activity, flame retardancy, and biocompatibility. Meanwhile, the assembled fibers-based supercapacitors displayed a high mass-specific capacitance (41.4 F·g −1 at a current density of 0.025 A·g −1 ) and good cyclic stability (93% capacitance retention after 1200 charge-discharge cycles). These superior properties enable the PEDOT: PSS/[BMIM]HSO 4 fibers to be woven into wearable smart fabrics, which exhibit excellent moisture wicking, breathability, and UV resistance. Meanwhile, this smart fabric can realize self-cooling in hot environments and electrical heating in cold conditions, demonstrating potential application for personal thermal management. Furthermore, the constructed PEDOT: PSS/[BMIM]HSO 4 fiber-based electrodes can effectively monitor various human motions as well as electrocardiography (ECG) signals. Thus, this study provides a green and facile strategy for designing advanced PEDOT: PSS-based fibers with high conductivity and opens up new avenues for the development of wearable electronics for energy conversion/storage, personalized healthcare monitoring, and human-machine interaction.

Intelligent wearable fabrics featuring multimodal sensors
capable
of detecting human physiological signals have attracted considerable
attention for next-generation health monitoring applications. Piezoelectric
and thermoelectric functional polymers can be simultaneously engineered
into fiber-based architectures; however, their sensitivity and synergistic
response under multiple physical fields remain insufficiently understood
and require systematic investigation. In this work, a three-dimensional
flexible PPSF sensing unit with dual thermoelectric and piezoelectric
response characteristics was developed by uniformly coating PEDOT/PSS
onto the surface and PVDF spacer filaments of a 3D spacer fabric via
in situ polymerization combined with phase separation, followed by
post-treatment with dimethyl sulfoxide (DMSO) and ethylene glycol
(EG). The fabrication process, surface morphology, and thermoelectric
and mechanical properties, as well as air permeability of the PPSF,
were comprehensively characterized. The Seebeck coefficient, electrical
conductivity, and power factor were systematically evaluated. The
optimized PPSF (5 vol % DMSO, 2 h EG treatment, 3 mm thickness) achieved
a Seebeck coefficient of 25.6 μV K –1 , an electrical
conductivity of 0.33 S·cm –1 , a power factor
of 84.7 μW·m –1 ·K –2 at room temperature, and a rapid response time of approximately
1 s under Δ T = 1 K. Thirty p-/n-type PPSF sensing
units were integrated in thermal parallel and electrical series to
fabricate a pressure–temperature dual-mode flexible sensor,
delivering output voltages of 15.3 mV (Δ T =
10 K) and 60.1 mV (Δ T = 40 K). Output voltage
stability tests showed a slight initial decline within 5 min, followed
by a stable plateau. In finger-pressing experiments, the flexible
sensor independently and simultaneously responded to temperature and
pressure stimuli, generating distinct voltage and current signals.

Improved ammonia (NH 3 ) sensor is proposed based on polyaniline (PANI) with poly(styrene sulfonic acid) (PSS) as an additive, which was produced by in-suit polymerization of aniline on flexible porous polyvinylidene-fluoride (PVDF) membranes and then treated with PSS aqueous solution. The whole film sensor fabrication process was low-cost and convenient in operation, suitable for large-scale commercial production. The results demonstrated that the appropriate addition of PSS could significantly improve the sensor response to NH 3 . The PSS-PANI/PVDF film sensor response was improved to approximately 70%, which was 2.8 times higher than that of the pure PANI/PVDF film with 25% response towards 1 ppm NH 3 at room temperature. Furthermore, it still showed an excellent response of 9.4% for 0.1 ppm NH 3 . The fabricated film sensor showed remarkable long-term stability with response decreases less than 5% after 30 days, and excellent flexibility under 10,000 repeated bending times with a response value degradation of only 15.1% towards 1 ppm NH 3 . The flexible PSS-PANI/PVDF film offers potential applications in smart wearable devices for detecting sub-ppm NH 3 under ambient conditions.

Considering the high thermal conductivity of copper material and the promoting effect of sulfonate ions on methane hydrate formation, in this study, copper nanowires coated with sulfonate polymer (CuNW@PSS) were used in methane hydrate experiments. The morphology of synthesized CuNW@PSS was confirmed by SEM and TEM, and the composition was analyzed by elemental analysis, it has clearly core–shell structure. The surface wettability of the material changed from hydrophilic to hydrophobic after sulfonate modification. In methane hydrate formation experiments, compared with PSS, CuNW@PSS can shorten the induction time by 78.5 %, from 61.87 ± 21.71 min to 13.28 ± 5.47 min, the growth rate increased by 130 %, from 0.6 ± 0.13 mmol/min to 1.38 ± 0.34 mmol/min. In addition, CuNW@PSS has good cycling and defoaming performance in the multi-cycle methane hydrate formation and dissociation experiments, which would have potential application for natural gas storage and transportation.

Herein, an enhanced lectrochemiluminescence (ECL) immunosensor was designed based on an efficient ECL bioprobe and first realized the quantitative analysis of human epididymis protein 4 (HE4). To obtain the efficient ECL bioprobe, a self-assembled mesocrystalline hybrid (TiO 2 MCs@rGO) was first prepared for loading luminol and 2-(Dibutylamino)ethanol (DBAE), which was explored as a new coreacant of luminol for the first time and triggered more stable and efficient ECL intensity than conventional luminol-H 2 O 2 system. Additionally, the high surface area and outstanding conductivity of TiO 2 MCs@rGO would effectively amplify the ECL intensity. Besides, the synthesized macromolecular complex (PEDOT/PSS/NiCo 2 O 4 NS) integrated the excellent conductivity of PEDOT/PSS and highly porous of NiCo 2 O 4 nanosheets was served as an efficient sensing matrix for further improvement of the analysis sensitivity. The developed ECL immunosensor exhibited excellent performance in the analysis of HE4 with a wide linear range of 1.0 × 10 −5 ˜1000 ng/mL and low detection limit of 3.3 × 10 −6 ng/mL, especially superior stability. The strategy provided promising application for early ovarian cancer monitor and diagnosis, and provoked a new idea for other tumor markers detection.

Hydrogel is a promising material for wearable electronics due to its good mechanical properties, electrical conductivity and body adaptability. However, subzero freezing and water loss under high temperature or prolonged placement are great challenges for hydrogels. Here, polyacrylic acid / poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PAA/PEDOT: PSS) ionogels were designed by entangling PAA and PEDOT: PSS chains with each other in a binary solvent system of water and ionic liquid (IL) and chemical cross-linking by N, N’ -methylene bisacrylamide (MBA). It has excellent mechanical properties (8.3 kPa, > 500 %), skin-adapted Young's modulus (<10 kPa), high conductivity (8.06 S·m −1 ), and strong adhesion (13.3 kPa). Ionogel has a sensitive response as a sensor (GF = 2.08, 0–200 %; GF = 3.64, 200–400 %; GF = 4.58, 400–510 %). Especially, the freeze-resistance and long-term moisturizing properties make ionogels exhibit long-lasting and robust utility. As a scalable application platform, we demonstrate the potential applications of this novel ionogel as a body-conformable electronic product in a series of conceptual demonstrations, including full range of human motion response, human–machine interaction (HMI), temperature signal detection and TENG device assembly.

Ionic electroactive polymer (iEAP) actuators are recognized as exceptional candidates for artificial muscle development, with significant potential applications in bionic robotics, space exploration, and biomedical fields. Here, we developed a new iEAP actuator utilizing high-purity single-walled carbon nanotubes (SWCNTs)-reinforced poly(3, 4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT: PSS, PP) hybrid electrodes and a Nafion/EMIBF4ion-exchange membrane via a straightforward and efficient spray printing technique. The SWCNT/PP actuator exhibits significantly enhanced electric conductivity (262.9 S/cm) and specific capacitance (22.5 mF/cm2), benefitting from the synergistic effect between SWCNTs and PP. These improvements far surpass those observed in activated carbon aerogel bucky-gel-electrode-based actuators. Furthermore, we evaluated the electroactive behaviors of the SWCNT/PP actuator under alternating square-wave voltages (1–3 V) and frequencies (0.01–100 Hz). The results reveal a substantial bending displacement of 6.44 mm and a high bending strain of 0.61% (at 3 V, 0.1 Hz), along with a long operating stability of up to 10,000 cycles (at 2 V, 1 Hz). This study introduces a straightforward and efficient spray printing technique for the successful preparation of iEAP actuators with superior electrochemical and electromechanical properties as intended, which hold promise as artificial muscles in the field of bionic robotics.

Microplastic pollution poses a significant threat to ecosystems and human health, necessitating efficient removal methods. In this study, a magnetic nanocomposite, Fe 3 O 4 /PSS/ZIF-67, was synthesized via a solvothermal method, utilizing poly(sodium p-styrenesulfonate) (PSS) to functionalize Fe 3 O 4 nanoparticles for the in situ growth of ZIF-67. Under ultrasound-assisted conditions, the adsorbent exhibited exceptional performance for polystyrene (PS) microplastics, achieving equilibrium within 15 min with a maximum adsorption capacity of 2816 mg/g. The adsorption process followed pseudo-first-order kinetics and the Langmuir isotherm model. Mechanistic analyses revealed that the removal was driven by synergistic effects of van der Waals forces, electrostatic interactions, hydrogen bonding, and π–π interactions. Furthermore, the Fe 3 O 4 /PSS/ZIF-67 demonstrated broad-spectrum removal capabilities for various microplastics (PP, PE, PET, PMMA, PVC, PA), organic dyes (AB 93, MB, MO, CR, CV, MG, R6G), heavy metal ions (Fe 3+ , Ni 2+ , Cu 2+ , Zn 2+ ), and antibiotics (TC, CIP), demonstrating its potential for wastewater treatment.

Accurate and sensitive detection of bilirubin, cholic acid, and Alanine aminotransferase (ALT) is essential for the early detection of hepatobiliary diseases in healthcare and the medical field. Integrating surface-enhanced Raman scattering (SERS) with deep learning algorithm has shown great application prospect in the early identification of markers of hepatobiliary diseases. Here, an regular Ag decorated Cu-Ag nanoisland-liked SERS biosensor (Ag@5/Ag-Cu@20/PSS) was constructed by using pattered sappire substrate as a template. An additional 5 mins of Ag nanofilm significantly improved the SERS signal intensity and homogeneity, and the sensitivity was enhanced by two orders of magnitude up to 10-10 M for 4-aminothiophenol (4-ATP). Importantly, deep learning algorithms included temporal convolutional networks (TCN), convolutional neural networks (CNN), recurrent neural network (RNN) and Transformer were used to deeply mine SERS spectral data of bilirubin, cholic acid and ALT, extract effective features, and establish an accurate classification and prediction model. Results indicating that the developed SERS biosensor combined with Transformer model demonstrated excellent accuracy (ACC) of 0.9816±0.0090 in qualitatively and quantitatively analyzing of bilirubin, cholic acid, and ALT. The successful application of the SERS biosensor will help improve the accuracy of early identification of bilirubin, cholic acid, and ALT disease markers and promote the early intervention and treatment of hepatobiliary diseases.

n-Si/PEDOT: PSS heterojunction solar cells are expected to be the alternative for photovoltaic technique for the potentially excellent power conversion efficiency and ease of processing. Herein, a multi-walled carbon nanotubes network coated with polydopamine (MWCNTs&PDA) was applied as an interlayer between silicon substrate and PEDOT:PSS film to enhance the performance of Si/PEDOT:PSS heterojunction device in this study. When the film was applied as an interlayer, the average reflectance of the device within the wavelength range 400–1000 nm dropped from 13.6 % to 8.33 %. The enhanced antireflection ability meant more photon-generated carriers were excited. The introduction of PDA reduced the contact angle from 84.5° to 47° on Si surface, and the minority carrier lifetime (τ) was 2.16 times increase. The high charge separation and improved junction effect of MWCNTs&PDA films incorporated between PEDOT:PSS and Si substrate result in advantageous networks of charge carriers, which is confirmed by the excellent open-circuit voltage (V oc ) 637 mV, short-circuit current density (J sc ) J sc 34.76 mA/cm 2 and fill factor (FF) 56.41 %. The power conversion efficiency improved to 12.49 % when the MWCNTs&PDA film was incorporated. The achievements of this study indicated that the MWCNTs coated with polydopamine as an interlayer is a promising material for excellent performance Si/PEDOT:PSS heterojunction solar devices.

Electrochromic devices are emerging as a futuristic technology for flexible electronics with the practical application values in energy-saving, displaying and military camouflage, however, the limitations in the optical, electrical and mechanical properties of the existing transparent conducting electrodes (TCEs) appear as a major obstacle for realizing high performance flexible electrochromic devices. In this work, we have proposed and demonstrated a fast-response and bendable polymer poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT: PSS) electrochromic device based on the embedded nickel (Ni) grid electrode. The Ni grid electrode, fabricated though patterned electroplating, has low sheet resistance (~1.3 Ω/sq), high transparency (~80%), excellent mechanical reliability and long-term chemical stability, exhibiting a figure of merit of 1250, surpassing the most existing TCEs. In addition, we have proposed a compact electrochromic architecture with the electrochromic PEDOT: PSS layer and solid polymer electrolyte being sandwiched between two embedded Ni grid electrodes. The device shows a short coloration and bleaching time (~1 s for 90% optical contrast), a high coloration efficiency (325 cm 2 /C) and excellent mechanical reliability (optical contrast retention ~80% after 1000 bending circles), paving a way for high performance flexible electronics.

Cation exchange membranes (CEMs) enabling selective monovalent cation transport are of critical importance for sustainable water treatment and resource recovery processes such as energy-efficient desalination and lithium recovery. However, achieving high monovalent selectivity remains challenging due to insufficient nanoscale control over ion–membrane interactions. In this study, we developed a high-performance monovalent CEM featuring biomimetic nanochannels via an in situ "seeding–counterdiffusion–growth" strategy. A positively charged polyaniline (PANI) layer and a ZIF-8 framework were constructed on a commercial cation-exchange membrane, followed by incorporating poly(4-styrenesulfonate) (PSS) into the ZIF-8 cavities to tailor the ion transport pathways. The resulting ZIF-PSS modified membrane demonstrated exceptional monovalent selectivity, with permselectivity values of P M g 2 + N a + = 47.7 and P M g 2 + L i + =36.6, respectively, while maintaining high ion fluxes ( J Na⁺ = 2.8 × 10⁻ 8 mol·cm⁻ 2 ·s⁻ 1 ; J Li⁺ = 2.3 × 10⁻ 8 mol·cm⁻ 2 ·s⁻ 1 ). Electrochemical analyses ( I–V and EIS) revealed that PSS incorporation promotes Mg 2 ⁺ accumulation and electric double layer overlap within the nanochannels, increasing interfacial resistance toward divalent ions. Gaussian simulations further indicated that sulfonic groups reduce the diffusion energy barrier for monovalent ions while hindering Mg 2 ⁺ transport via a spatial confinement–ionic anchor mechanism. The modified membrane presented high mono-/divalent cation permselectivity among state-of-art CEMs and demonstrated long-term performance stability. This work provides an applicable design principle and fundamental insights of biomimetic ion-selective membranes for highly efficient mono/divalent ion separation in desalination and resource recovery.
