Thermal transfer printing (TTP) offers scalable patterning for electronic textiles, but poor mechanical compatibility and weak adhesion at the conductor–fabric interface often cause failure during deformation and washing. Here we report a TTP strategy that produces mechanically robust and wash‑durable textile electrodes using a dual‑crosslinked conductive composite (DCCC). The composite integrates PEDOT:PSS with sorbitol as a dopant/plasticizer, thermoplastic polyurethane (TPU) as a viscoelastic binder, and (3‐glycidoxypropyl) trimethoxysilane (GOPS) as a coupling crosslinker. GOPS covalently stabilizes the PEDOT:PSS network and chemically links it to TPU, while TPU chains interdiffuse with a hot‑melt adhesive (HMA) during transfer. Simultaneously, molten HMA penetrates textile pores to form mechanical interlocking, enabling strong bonding on diverse fabrics. The resulting electrodes exhibit high adhesion, with peel strength above 900 N/m and lap‐shear strength above 7.85 MPa. During machine washing, the sheet resistance initially decreases because of washing‐induced surface conditioning and then stabilizes, allowing the electrodes to retain electrical performance after 50 standard washing cycles. They also remain stable after 240 days of water immersion and 100 h at 85°C/85% RH, and tolerate repeated bending and abrasion. We demonstrate practical use in motion‑robust wearable ECG monitoring and low‐voltage Joule‑heating textiles for automatic thermal regulation. This work provides a general interface design for reliable, mass‑producible electronic textiles.

Flexible capacitive pressure sensors are crucial for applications in electronic skin, artificial intelligence, and wearable medical devices. Despite their potential, conventional sensors often suffer from low pressure sensitivity, particularly in high‐pressure environments, and complex microstructure construction methods. This study addresses these limitations by developing a novel flexible capacitive pressure sensor based on a composite dielectric layer consisting of carbon nanotubes (CNTs), thermally expandable microspheres (TEMs), and polydimethylsiloxane (PDMS), with a 3D direct ink writing (DIW) technology. The CNTs‐TEMs synergy modulates both mechanical and dielectric response in capacitive sensors, achieving a two‐order‐of‐magnitude enhancement in sensitivity compared to that of CNT‐only filler system. The groove‐like microstructure on the surface of the dielectric layer enables rapid and stable air expulsion to boost dielectric constant change and sensitivity under pressure. The proposed sensor exhibits a maximal sensitivity as high as 3.09 kPa ⁻¹ in the wide pressure range of 0–500 kPa, and a detection limit as low as 16.7 Pa. Furthermore, the sensor shows excellent pressure resolution of 0.3%, cycling stability over 40 000 cycles, and can accurately monitor various human activities, demonstrating its potential for applications in health monitoring and flexible electronics.

The rapid growth of industrial activities has significantly increased oil demand, leading to wastewater contamination with oil and causing severe environmental pollution. Traditional oil–water separation techniques, such as gravity separation, filtration, and chemical treatments, are hindered by low efficiency, high energy consumption, and secondary pollution. Membrane separation technology has emerged as a promising solution due to its simplicity, low energy consumption, and high efficiency. In this study, we report the fabrication of a novel polyvinylidene fluoride/ethylene–vinyl alcohol (PVDF/EVOH) nanofibrous membrane (NFM) with a unique balsam-pear-skin-like structure using a one-step electrospinning process. The membrane’s superhydrophobicity and superoleophilicity were achieved via water vapor-induced phase separation (WVIPS), by optimizing the rheological properties and mixing ratio of EVOH and PVDF precursor solutions. The resulting PVDF/EVOH (PE12-3) NFM exhibits exceptional properties, achieving separation efficiencies of 99.4% for heavy oil and 98.9% for light oil, with a heavy oil flux of 18,020 L m⁻² h⁻¹—significantly surpassing previously reported performances. Additionally, the membrane shows excellent recyclability, making it ideal for large-scale oil–water separation in wastewater treatment and environmental remediation. This one-step fabrication strategy offers an efficient and scalable approach for developing high-performance membranes to tackle oil pollution in water.

Enhancing the sensitivity and extending the linear sensing range of flexible pressure sensors are crucial for their development and incorporation in wearable electronics. Conventional sensors face a trade‐off between sensitivity and linear sensing range, which is often limited by the monotonicity of materials and structural design. To address this challenge, a new piezoresistive flexible sensor is developed in this work, drawing inspiration from the intricate microstructure and pressure‐sensing capabilities of human skin. This advanced sensor is constructed with a dual‐layer resistive sensing design, which includes an external conductive layer comprising of MXene/Ag composite and an internal carbon nanomaterial conductive network. The design incorporated bionic micro‐spines and multilayer porous microstructures with microcapsules to optimize the overall performance. This scalable and economical approach yielded a sensor that surpassed human tactile resolution, and the sensor can adeptly monitor comprehensive human motions and respiratory rhythms and recognize spoken language. In addition, it exhibited reliable photothermal sterilization performance, making it suitable for long‐term health diagnostics and treatment. The proposed sensor demonstrated immense potential for applications in physical health monitoring, motion detection, electronic skin, and human–computer interactions.

Perylene dianhydride (PDA), a low-cost, readily available, and chemically stable organic cathode material, has received extensive attention in recent years. However, its large π planar structure often results in poor or difficult-to-control micro-nanostructures during conventional electrode processing methods, such as dry mixing. This leads to limited cycling life and rate performance. Here, we present a simple electrospinning strategy for controlling the micro-nanostructures of electrodes based on PDA, carbon black Super P (SP), and polyvinylidene fluoride (PVDF) composites. The spinnable PVDF polymer not only provides the micro-nanofibrous structure but also realizes the function of the binder in the electrodes, offering the hierarchical micro-nanostructures of the electrospun PDA (PDA-es) electrodes. The unique structure enables PDA-es electrodes to possess rapid charge transport properties and ultrafast reaction kinetics. Specifically, the PDA electrode based on high molecular weight electrospun PVDF (PDA-es-H) demonstrates a high initial specific capacity (126.2 mA h g⁻¹), robust cycling stability (∼95% and ∼60% capacity retention after 100 cycles at 50 mA h g⁻¹ and 1000 cycles at 100 mA h g⁻¹, respectively), and excellent rate performance. This study provides a straightforward and efficient strategy for realizing the micro-nanostructures of organic electrodes for high-performance lithium-organic batteries.

Recent advances in n-type conducting polymers are beginning to rival those of p-type materials. Notably, the n-type conducting polymer poly(benzodifurandione) (PBFDO) demonstrates a notable Seebeck coefficient along with exceptionally high electrical conductivity, positioning it as a promising n-type thermoelectric material with substantial research potential. Despite its promise, the exploration of PBFDO’s thermoelectric properties and the development of related thermoelectric devices have been limited. In this study, we introduce a flexible thermoelectric device that utilizes a combination of the p-type polymer poly(3,4ethylenedioxythiophene):polystyrene sulfonate and the n-type polymer PBFDO, using a straightforward print-and-fold technique. This approach enabled the production of flexible devices with thermoelectric generators whose properties were assessed. The polymer films and the resultant devices demonstrated commendable performance stability even after being subjected to 1,000 bending cycles at a 90° angle. Our findings corroborate the potential of PBFDO as a viable material for flexible thermoelectric applications, a development that is eagerly anticipated in the field.
