The infrared radiation heating textiles have attracted increasing attention aiming to address the warmth retention issue in cold weather. It still remains challenging to develop high-efficiency heating products with fast heating rate and stable heat generation. Here, a highly flexible, efficient, and wearable infrared radiation heating carbon fabric (CF) was rationally constructed using textile forming technique. Inspired by the biomimetic adhesion, the carbon fabric was chemically modified by dopamine to improve the interfacial activity on the fiber surface. Infrared radiation materials including tourmaline, ZrO 2 , and medical stone nanoparticles (NPs) were successfully introduced into the carbon fabric through interfacial adhesion. The permanent spontaneous polarization of both CF matrix and infrared radiation NPs can induce an enhanced current in the heater by creating an additional electrical field, benefiting to produce a fast electrothermal response and favorable heat preservation. It was found that 30% tourmaline@PDA@CF, 9% ZrO 2 @PDA@CF, and 15% medical stone@PDA@CF exhibited excellent heat generation performance among different samples with different ingredients. The temperature can be rapidly raised up from room temperature to 58.3 °C, 60 °C, 59.5 °C respectively for these three samples in 10 min under a voltage of 10 V. More importantly, the composite CF is highly shape adaptive and can be fully integrated into a neck guard or industrial carpet for real application. It is expected that this infrared radiation heating CF can be widely applied in the fields of personal warmth, physical therapy, biomedical treatment, and wearable flexible electronics.

Polar bears have special hairs with porous microstructure and hydrophobic surface, which help them keep warm in both cold air and water. Due to the large difference in temperature and heat transfer process of aquatic and terrestrial environments, it is quite difficult for typical thermal insulating materials to maintain ideal insulation in air and underwater at the same time. To tackle this problem, we report here a superhydrophobic porous textile mimicking the outstanding thermal insulating properties of polar bear hairs. Fibers used to weave this textile are fabricated by a freeze-spinning method, providing them aligned porous microstructure. After a superhydrophobic surface treatment, the obtained textile with porous microstructure and superhydrophobic surface is capable of capturing air in its multi-scale porous structure, promising an excellent thermal insulating ability in both air and water environments. Our study paves a way for the bioinspired engineering of thermal insulation textiles both in air and underwater.

Health risks in an extremely cold environment make warm retention equipment highly desirable. However, creating materials with a high warm retention performance and robust mechanical property to durably prevent against the harsh conditions is highly challenging. Herein, we report on a one-step and facile strategy to fabricate stretchable and superelastic fibrous sponges by creating unique “stiff–soft” polymer networks within fibers and bonding architecture among fibers. The premise of this design is that stiff polystyrene can endow materials with rigidity and soft polyurethane can absorb energy during mechanical deformation. Benefiting from this systematic tailoring for the polymer and assembling networks, the resultant fibrous sponges exhibit a unique tensile recovery property, a large breaking elongation of 70%, and an outstanding resilience for resisting 100 cyclic compressions with 50% strain under −50 °C. Moreover, the fibrous sponges possess dramatic characteristics of high porosity (∼99.31%), ultralight property (volume density = 7.68 mg cm–3), and effective warmth retention (thermal conductivity = 27.6 mW m–1 K–1), as well as technical features of the simple assembly process to scale up easily. The preparation of fibrous sponges provides a new vision for developing ultralight and efficient warmth retention materials.

Functional textiles with efficient sweat releasing and thermal insulating play a pivotal role in maintaining physiological comfort in cold winter. However, the breathability and warmth have conflicting structural demands on the conventional fabric. Here, a porous polyimide film (PIF) with tunable sweat release capability was prepared by growing a graphene layer through laser-ablation strategy. Jungle-like graphene layer offers the porous PI film with distinct advantages, including a desired super hydrophobic performance (water contact angle =153°), rapid air permeability (1572 g/m 2 ·24 h), quick drying function based on high photo-thermal and electro-thermal conversion efficiency, and outstanding thermal insulating capability (0.033 W/m·K). Moreover, the graphene layer can also be custom printed into various patterns, which expanded the application scenarios for wearable flexible electronics. Overall, this Janus design offered insight into the proactive control of sweat release and heat transfer within the hierarchical and interconnected network, providing promising benefits to the development of multifunctional drying and warming textiles.

Warmth retention equipment for personal cold protection is highly demanded in freezing weather; however, most present warmth retention materials suffer from high thermal conductivity, weak mechanical properties, and strong flammability, resulting in serious security risks. Herein, we report a facile strategy to fabricate nano-/microfibrous sponges with superelasticity, robust flame retardation, and effective warmth retention performance via direct electrospinning. The three-dimensional fluffy sponges with low volume density and high porosity are constructed by accurately regulating the relative humidity; meanwhile, the mechanically robust polyamide-imide nanofibers with high limit oxygen index (LOI) are innovatively introduced to improve the structural stability and flammability of the nano-/microfibrous sponges. Strikingly, the developed nano-/microfibrous sponges exhibit ultralight characteristics (6.9 mg cm–3), superelasticity (∼0% plastic deformation after 100 compression tests), effective flame retardant with LOI of 26.2%, and good heat preservation ability (thermal conductivity of 24.6 mW m–1 K–1). This work may shed light on designing superelastic and flame-retardant warmth retention materials for various applications.

We report a facile strategy for preparing ultralight, mechanically robust, and washable heat-retaining materials via solution blow spinning technology and thermal crosslinking. Fluffy microfibrous assemblies with nonwoven structure were fabricated by blending fibers of stiff and soft polymers and creating a bonding architecture among them. The premise of this design is that polystyrene, which is stiff, can endow materials with rigidity, while thermoplastic polyurethane, which is soft, can absorb energy during mechanical deformation. Moreover, the stability of the sponge was improved by using tris (2-methyl-1-aziridine propionate; TTMA) as a crosslinking agent. The optimized microfibrous sponges present excellent mechanical properties with a large breaking elongation of 42.1% and outstanding resilience in resisting 100 cyclic compressions at 40% strain. Furthermore, the microfibrous sponges exhibit a low volume density of 33.32 mg/cm3, effective heat-preservation ability (low thermal conductivity: 23.1 mW/m·K) and excellent washability. The preparation of microfibrous sponges via solution blow spinning can be a novel route for developing ultralight and superelastic heat retention materials.

Heat insulation and solar energy use are attractive strategies to cope with the serious and external cold environment. Here, silver nanowires (AgNWs) with high purity and aspect ratio were synthesized by polyol method and PVDF/AgNWs nanofiber membranes were prepared by electrostatic spinning. We investigated the warmth retention properties of nanofiber membranes using a heating table and simulated sunlight as the heat source, respectively. The results showed that the nanofiber membrane doped with 2 wt % AgNWs had a high porosity of 84% and thus a low thermal conductivity of 18 mW m −1 K −1 . Meanwhile the nanofiber membrane exhibited stable and long-lasting heat insulation behaviors and the surface temperature of the fiber membrane could reach nearly 43 °C after 5 min of irradiation with a 100 mW cm −2 light intensity and about 70 °C after 2 min of irradiation with a 300 mW cm −2 light intensity. In addition, the nanofiber membrane showed hydrophobicity with a water contact angle of 138° and breathability with air permeability of 75 mm s −1 . The stress and strain of the nanofiber membrane was 3.6 Mpa and 211.3% respectively.

Extremely low temperature has posed huge burden on the public safety concerns and global economics, thereby calling for high-performance warmth retention materials to resist harsh environment. However, most present fibrous warmth retention materials are limited by their large fiber diameter and simple stacking structure, leading to heavy weight, weak mechanical property, and limited thermal insulation performance. Herein, an ultralight and mechanically robust polystyrene/polyurethane fibrous aerogel by direct electrospinning for warmth retention is reported. Manipulation of charge density and phase separation of charged jet allows for the direct assembly of fibrous aerogels consisting of interweaved curly wrinkled micro/nanofibers. The resultant curly wrinkled micro/nanofibrous aerogel possesses low density of 6.8 mg cm −3 and nearly full recovery from 1500-cycle deformations, exhibiting both ultralight feature and superelastic property. The aerogel also shows low thermal conductivity of 24.5 mW m −1 K −1 , making synthetic warmth retention materials superior to down feather possible. This work may shed light on developing versatile 3D micro/nanofibrous materials for environmental, biological, and energy applications.

Long-term exposure to cold conditions can cause damage to the body, which makes cold prevention equipment urgently needed. However, the most commonly used fibrous warmth retention materials have drawbacks of heavy weight, poor mechanical properties, flammability, and inefficient thermal insulating performance. Herein, we propose a simple and feasible strategy to prepare nanofiber/aerogel microfiber sponges (NAMS) with dual-network structures for warmth retention by direct electrospinning. The aerogel fibers are prepared by regulating the phase separation behavior of the jet, while flexible nanofibers are introduced between the aerogel fibers to construct dual-network structures in the sponge. The obtained NAMS is lightweight (3.44 mg cm–3) and exhibits robust mechanical properties (almost no plastic deformation after enduring 500 stretching cycles and 1000 compression cycles), and efficient warmth retention properties (thermal conductivity of 23.92 mW m–1 K–1). Furthermore, the introduction of a flame retardant enables the NAMS to possess remarkable flame resistance, with a limiting oxygen index of 28.7%. The development of NAMS offers a promising avenue for future advancements in ultralight, flame-retardant, and high-efficiency warmth retention materials.

Both thermal management and electricity generation are becoming two basic functions for next-generation clothing integrated with wearable electronics . However, such versatile textiles with a simple design and great comfort have been rarely reported. Here, we propose a tri-layer textile that not only realizes solar and passive radiative warming but also harvests biomechanical energy to generate electricity. The textile is achieved by assembling photothermal nanoparticles on an infrared-reflective and conductive fabric with a tribo-negative polytetrafluoroethylene (PTFE) nanofiber membrane on the backside. The textile offers both a minimal thermal emissivity (down to 11.0%) and a maximum solar absorptivity (up to 83.7%), effectively suppressing radiation heat loss and boosting the harvested solar-thermal energy. Wearing such a textile enables a 3 °C drop of the indoor heating setpoint compared to a cotton textile, saving 25.2–100% of building energy consumption in ten cities worldwide. Moreover, the textile can serve as a single-electrode triboelectric nanogenerator . Remarkably high outputs (150–352 V, 7.5–27.8 μA) can be attained upon hand touching with different forces (14.7–44.0 N) and frequencies (0.9–3.9 Hz), which can power 41 LEDs. This textile opens a promising direction on how to develop a multifunctional energy-saving and electricity-generation textile while keeping thermal comfort for wearers.

This study presents a solvent-free, facile synthesis of a bio-based green antibacterial agent and aromatic monomer methacrylated vanillin (MV) using vanillin. The resulting MV not only imparted antibacterial properties to coatings layered on leather, but could also be employed as a green alternative to petroleum-based carcinogen styrene (St). Herein, MV was copolymerized with butyl acrylate (BA) to obtain waterborne bio-based P(MV–BA) miniemulsion via miniemulsion polymerization. Subsequently, MXene nanosheets with excellent photothermal conversion performance and antibacterial properties, were introduced into the P(MV–BA) miniemulsion by ultrasonic dispersion. During the gradual solidification of P(MV–BA)/MXene nanocomposite miniemulsion on the leather surface, MXene gradually migrated to the surface of leather coatings due to the cavitation effect of ultrasonication and amphiphilicity of MXene, which prompted its full exposure to light and bacteria, exerting the maximum photothermal conversion efficiency and significant antibacterial efficacy. In particular, when the dosage of MXene nanosheets was 1.4 wt%, the surface temperature of P(MV–BA)/MXene nanocomposite miniemulsion-coated leather (PML) increased by about 15 °C in an outdoor environment during winter, and the antibacterial rate against Escherichia coli and Staphylococcus aureus was nearly 100% under the simulated sunlight treatment for 30 min. Moreover, the introduction of MXene nanosheets increased the air permeability, water vapor permeability, and thermal stability of these coatings. This study provides a new insight into the preparation of novel, green, and waterborne bio-based nanocomposite coatings for leather, with desired warmth retention and antibacterial properties. It can not only realize zero-carbon heating based on sunlight in winter, reducing the use of fossil fuels and greenhouse gas emissions, but also improve ability to fight off invasion by harmful bacteria, viruses, and other microorganisms.
