Abstract Intelligent breathable membranes with multiple functions attach wide attentions of people which provide protection and comfort to meet the pressing demand for future protective clothing. We proposed a novel thermal energy regulated and thermochromic composite film with temperature-sensitive “breathable” stomata consisted of thermochromic nanofibrous membrane (TC-NFM) and thermo-sensitive polyurethane (PU) film. Thermochromic nanoencapsulated phase change materials (TC-NPCMs) were introduced as functional fillers into polyvinyl alcohol/water-soluble polyurethane (PVA/WPU) solution for electrospinning process. And methylated melamine–formaldehyde (MMF) was innovatively used to modify the water resistance of TC-NFM. By adjusting the molecular weight of the soft segment, the thermo-sensitive PU film was successfully prepared. Consequently, the prepared TC-NFM exhibited high enthalpy of 44.3 J g −1 and kept superior energy storage and release property even after 100th cyclic experiments. The water vapor permeability of thermo-sensitive PU film was triggered near the comfortable temperature of the human body. The results presented here might facilitate improvements in the field of thermal regulation clothing, intelligent clothing, wearable temperature sensor and reversible thermochromic coating materials.

In this study, the carbon quantum dots/thermoplastic polyurethane (CQDs/TPU) flexible composite film is prepared by solvent and electrospinning methods. The effects of CQDs concentrations on the microstructure, mechanical property, breathable moisture-permeable property, and sensing performance of the composite films are investigated. Results show that the composite film prepared by solvent method has a large strain range, and its sensitivity increases with strain, but exhibits poor breathable moisture-permeable property and linearity. The fibers inside the electrospinning composite membrane are arranged in a staggered manner to form a good three-dimensional conductive network. As the concentration of CQDs increases, the tensile strength at break gradually decreases and the tensile strength at break gradually increases. The composite film has good breathability and moisture permeability, with a maximum air permeability of 2.44 L/(m 2 ·s). The electrospinning method composite film has a smaller strain range but high sensitivity with a GF value of up to 53.3, better linearity, superior breathable moisture-permeable property and 4.67 times of air permeability compared to the composite film by solvent method.

In order to make better use of wool powder and explore the feasibility of replacing pigment with dyed wool powder, the dyeing behavior of wool powder was studied firstly. Then, we conducted a series of tests and analyses of the microcosmic structure and properties of powder before and after dyeing. BET test results revealed that the specific surface area of original powder was larger than that of dyed powder. TG and DMA tests indicated that the dyed powder had better thermal stability than the original powder. At last, the dyed wool powder and pigment were mixed and printed on cotton fabric. The dry/wet-rubbing fastness and moisture permeability of cotton fabric printed with dyed powder are better than those of cotton fabric printed with pigment. This indicates that the waste- wool fiber can be processed into applicable printing pigments, which is environmentally friendly and makes full use of natural resources.

The application of aerogels in textiles is limited because their poor moisture permeability and mechanical properties. Aerogel flowers with down-like structures for clothing filling are prepared by laser cutting bacterial cellulose. The nanoporous structures of the aerogels maintained excellent heat preservation performance, and the large pores between flowers provided a channel for water vapor transmission. Moreover, the rigid silica coating on the nanofiber skeletons enabled them to rebound in a timely manner after being subjected to compression. The resulting vest exhibits better thermal insulation when it is 0.8 cm thinner than the down vest. This strategy should expand the potential applications of aerogel materials in the field of personal thermal management.

The progression of wearable electronic devices has highlighted the need for flexible electronics that combine good conductivity with prolonged user comfort. However, simultaneously regulating the thermal and humidity comfort of the human body without compromising electronic performance remains a major challenge. This research introduces a liquid metal-embedded conductive aerogel (LeCA) to address the challenges of developing flexible circuits with high electrical performance, thermal insulation, and moisture permeability for wearable applications. By employing moisture absorption-induced phase separation in a thermoplastic polyurethane (TPU) matrix, an asymmetric porous structure is developed that decreases the thermal conductivity of the TPU film and spatially confines liquid metal particles to the upper layer of the TPU film. A direct writing method is demonstrated to facilitate the sintering of liquid metal particles into conductive patterns at targeted regions, resulting in an ease-of-fabrication manner for the development of flexible circuits. The findings present LeCA as a promising candidate for the development of wearable devices, combining the essential attributes of conductivity, thermal management, and user comfort in a single, flexible platform.

Super-hydrophobic fibrous materials are highly sought after for improving protective performance and wearer comfort. However, developing durable superhydrophobic fabrics with exceptional moisture permeability and strong resistance to water penetration remains a considerable challenge. To address this, we propose a simple, yet efficient method for producing PVDF/FPU superhydrophobic nanofibers via direct coaxial electrospinning. The nanofibers exhibit stable hierarchical micro–nano-roughness, featuring numerous integrated nano-protrusions derived from the shell solution. Further modification with low-surface-energy FPU enhances the super-hydrophobicity. Additionally, the PVDF/FPU nanofibrous membranes possess a finely structured hydrophobic porous network, characterized by small pore size and high porosity, which ensures outstanding water penetration resistance while Maintaining high moisture permeability. As a consequence, the resultant membranes display remarkable comprehensive waterproof and breathable properties with high water vapor transmission rate of 9.3 kg m −2 d −1 , excellent hydrostatic pressure of 94 kPa, as well as good superhydrophobic property with water contact angle of 153°, suggesting great promise as exceptional candidates for personal protection and comfort management.

Stretchable epidermal electronics with stable electrical performance have been widely applied in numerous fields, including advanced medical therapy, wearable electronics, soft robotics, and human–machine interaction. However, conventional stretchable devices, which typically integrate a pliant substrate and a conductor, often encounter inferior electrical performance under sustained or intense stretching due to poor stretchability, limited permeability, and the notable disparity in Young's modulus between the substrate and the conductor. This mechanical discord intensifies problems such as reduced durability and inconsistent conductivity. In this work, we address these limitations by devising a liquid metal-based flexible conductor via an innovative direct coating method. This conductor, supported by an electrospun fiber nanomesh, reveals markedly enhanced permeability through a pre-stretch activation process. The resulting electrode demonstrates remarkable electrical conductivity reaching 3730 S cm −1 , superior permeability with a water vapor transmission rate of 40.2 g m −2 h −1 , and extraordinary stretchability (>2000% strain), coupled with exceptional mechanical durability. The liquid metal fiber mat structure allows for the creation of breathable, on-skin electronics capable of long-term electrophysiological monitoring, rendering it ideal for continuous health monitoring applications. Stretchable and moisture-permeable LM-SBS electrodes for high precise and long-term electrophysiological monitoring.

Chemical protective clothing is crucial for shielding operators from toxic and hazardous substances. However, the limited moisture permeability of these garments significantly affects worker comfort and functionality over long periods. In this study, we introduce a novel graphene oxide/polyurethane composite membrane with an innovative alternating layer structure and improved interlayer bonding, produced through a simple, scalable layer-by-layer assembly method. The outstanding L-GO/PU membrane offers robust chemical protection for up to 24 h against harmful agents like mustard gas and dichloromethane, while also showing excellent resistance to both acidic and alkaline solutions. With a moisture permeability of 3116 g m −2 d -1 , this membrane ensures optimal comfort during extended use. Additionally, it demonstrates remarkable resistance to swelling, maintaining its structural integrity for 27 days during prolonged immersion in water. The L-GO/PU composite stands out as an excellent choice for chemical protective gear, combining high toxicity resistance with superior moisture management capabilities.

Graphical In this study, we synthesized an anionic polyacrylate water repellent and for the first time utilized it to enhance the moisture permeability in PVC/EVA membranes. The common polyvinyl chloride (PVC) gloves affect moisture and air permeability due to their dense nature, affecting the wearing comfort. Inspired by moisture-permeable fabrics, this study was conducted to enhance the moisture permeability of PVC/EVA membranes by introducing ethylene vinyl acetate copolymer (EVA) blended with PVC to form a membrane and coating one side of the membrane with a polyacrylate water repellent. The experimental results showed that the water contact angle of the upper (85°) and lower surfaces (99.4°) of the PVC/EVA membrane produced a significant difference. This difference endows the membrane with different wettability.The water vapor transmission of the membranes increased from the initial 163.25 g/m 2 ·24h to 862.9 g/m 2 ·24h. The moisture permeability and thermal conductivity of PVC/EVA membranes were significantly improved. After 30 min in the thermal conductivity test, the temperature of the palm covered with PVC/EVA membranes reached 34.7 °C, which was 0.8 °C higher than that of the palm covered with pure PVC membranes. The SEM images show that the PVC/EVA membrane generated more particles and pores. The results of XRD, TG/DTG, and tensile tests showed that the crystal structure and mechanical strength of the membranes remained unchanged, while their thermal stability improved.

M ultifunctional m icro f iber s ynthetic l eather (MMFL) with antibacterial activity, air permeability, moisture transmission, UV resistance, and mechanical robustness, is highly needed by advanced applications. However, achieving these integrated functionalities often requires complex designs and high filler loadings, leading to aggregation and compromised mechanical performance. Here, we propose a low-filler-content strategy using only 2–5 wt% of silver-decorated l ignin- h ybrid h ollow s ilica sphere s (Ag@LHHSs) in a w aterborne p olyurethane (WPU) to fabricate MMFL with integrated functionalities. The superior performance stems from the synergistic structure-function design of Ag@LHHSs: 1) uniformly distributed Ag n ano p articles (NPs) generate ·OH radicals, providing strong antibacterial efficacy, while simultaneously coordinating with WPU carbonyl/amine groups to enhance interfacial adhesion without compromising mechanical integrity; 2) lignin shell, rich in hydroxyl and sulfonic groups, contributes to UV protection and forms hydrogen bonds with WPU, further improving compatibility; 3) the hollow architecture creates free volume, enhancing breathability and moisture permeability. With only 2–5 wt% Ag@LHHSs, our MMFL achieves antibacterial efficiency of exceeding 99 %, air permeability of 283.4 mm/s (26.0 % higher than neat WPU), and 2 ·24 h water vapor transmission of 7120 g/m 2 (171.1 % improvement), meanwhile maintaining UV resistance and mechanical robustness. This work provides a promising strategy for developing lightweight, low-cost, multifunctional synthetic microfiber leathers via rational nanofiller design and interfacial engineering.

Drug delivery systems (DDSs) based on micro-and nano- fibrous membrane have been developed for decades, in which great attention has been focused on achieving controlled drug release. However, the study on the integrated performance of these drug-loaded membranes in the use of in-vitro drug delivery dressing is lacking, as clinical medication also needs consideration from the perspectives of wound safety and patient convenience. Herein, a trilayered hierarchical porous ethyl cellulose (EC) fibrous membrane based DDS (EC-DDS) was developed by electro-centrifugal spinning. Significantly, the hierarchical porous structure of the EC-DDSs with high specific surface area (34.3 m 2 g −1 ) and abundant long-regulative micro-and nano- channels demonstrated its merits in improving the hydrophobicity (long-term splash resistance (CA > 130°) and prolonging the drug release (the release time of ~80 % tetracycline hydrochloride (TCH) prolonged from 10 min to 24 h). Meanwhile, the trilayered EC-DDS also revealed excellent biocompatibility, antibacterial activity, air permeability, moisture permeability, water absorption capacity, mechanical strength, and flexibility. With these excellent integrated features, the EC-DDS could prevent external fluids, avoid infection, and provide comfort. Furthermore, this work also provides a new guide for the high-efficiency fabrication of porous fibrous membranes.

The treatment of severely damaged wounds is a serious challenge as these wounds have poor self-healing capacity, take longer to heal, and are prone to becoming chronic wounds. To solve this problem, PCL/gelatin electrospinning nanofiber membranes were combined with rGO-loaded chitosan non-woven fabrics to prepare biomimetic bilayer skin scaffolds. Among them, the PCL/gelatin nanofiber membrane was used to simulate the epidermis layer with a dense structure, and the chitosan non-woven fabric was used to simulate the dermis layer with a loose structure. When the concentration of the spinning solution was 7 %, and the average fiber diameter was 241 nm, HaCaTs had the best cell proliferation and adhesion, and the re-epithelialization process was fast. To enhance the induction effect of scaffolds on dermal cells, the electroactive substance rGO was used to give the scaffold electrical conductivity . Considering the biocompatibility, the concentration of GO dispersion was controlled at 1 mg/mL, and the obtained [email protected] 1rGO scaffolds had high conductivity, as well as the improved mitochondrial membrane potential of HFF-1 s which increased cell viability . So the induction of HFF-1 s migration was obvious. After cross-linking composite scaffolds with glutaraldehyde , the scaffolds still showed good cytocompatibility, at the same time, the peel strength was increased from 7.21 cN to 350 cN, and the structural stability of the nanofiber membrane layer in the liquid environment was also enhanced. Both the moisture absorption and moisture permeability of composite scaffolds were improved, which could maintain the moist environment of the wound to a certain extent. Altogether, results showed that electroactive biomimetic bilayer fibrous scaffolds have great application potential in promoting skin tissue regeneration.
