The phase change material (PCM) microcapsule is a common high-performance storage technology of thermal energy. However, the organic wall with low thermal conductivity for PCM reduces the efficiency of heat storage and release. In this study, the novel carbon nanotube-doped phase change materials (C-PCMs) were developed. Scanning electron microscope test (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and the thermogravimetric analysis/infrared spectrometry (TG-IR) were used to analyse the composite structure and thermal performances. The results indicate that C-PCMs are small and regular in spherical shape. When C-PCMs suffer from heat, the shell can maintain integrity below 165 °C. Furthermore, the carbon nanotubes in the shell play as a channel to connect the inside with the outside and improve the efficiency of heat transfer. The DCS test of the samples showed that the latent heat of C-PCMs and PCMs were 112.25 J/g and 116.18 J/g, respectively. The initial phase transition temperature of C-PCMs is 28.97 °C, which is 0.5 °C lower than that of PCMs. The results of the model room test suggested that the composite filled with C-PCMs reduces indoor temperature fluctuations and exhibits the potential for enhancing energy savings and the thermal comfort of buildings.

Wet comfort is an important indicator for evaluating human wearing comfort, and personal moisture management fabrics can quickly transfer sweat from the skin surface to meet the human body's requirements for wet comfort. Although cotton fabrics have an excellent water absorption capacity, the inability of moisture to transfer quickly causes the fabrics to cling to the skin and causes discomfort. Here we demonstrate personal moisture management cotton fabric by two-step grafting treatments, which are relatively simple and usually do not fall off as easily as a simple coating process. Moreover, unlike traditional double-layer or sandwich structures that absorb water and grow heavy, the fabric's quick-drying qualities are accomplished by expanding the area of water evaporation. According to the results of liquid moisture management and water evaporation rate tests, this fabric's moisture diffusion radius is 5 mm larger than that of pure cotton fabrics, and its evaporation rate can reach 0.2082 g/(m2 · d). In addition, it is also suitable for high-volume apparel fabrics. This work paves the way for personal moisture management cotton fabric.

Skin-like functional membranes with liquid resistance and moisture permeability are in growing demand in various applications. However, the membranes have been facing a long-term dilemma in balancing waterproofness and breathability, as well as resisting internal liquid sweat transport, resulting in poor thermal–wet comfort. Herein, a novel electromeshing technique, based on manipulating the ejection and phase separation of charged liquids, is developed to create triboelectric nanostructured nano-mesh consisting of hydrophobic ferroelectric nanofiber/meshes and hydrophilic nanofiber/meshes. By combining the true nanoscale diameter (≈22 nm), small pore size, and high porosity, high waterproofness (129 kPa) and breathability (3736 g m −2 per day) for the membranes are achieved. Moreover, the membranes can break large water clusters into small water molecules to promote sweat absorption and release by coupling hydrophilic wicking and triboelectric field polarization, exhibiting a satisfactory water evaporation rate (0.64 g h −1 ) and thermal–wet comfort (0.7 °C cooler than the cutting-edge poly(tetrafluoroethylene) protective membranes). This work may shed new light on the design and development of advanced protective textiles.

Adaptive moisture and thermal management cotton fabrics can maintain human physiological comfort without requiring space heating or cooling, aligning with the goals of sustainable development, carbon neutrality, and carbon peak. However, the moisture and thermal management performance and wearing comfort of cotton fabrics require further study. In this study, mist polymerization technology and the “grafting through” polymerization method were used to graft poly[2-(2-methoxyethoxy) ethoxyethyl methacrylate] (PMEO2MA) onto the inner surface of cotton fabric and poly[ N,N -dimethyl(methacryloylethyl)ammonium propane sulfonate] (PDMAPS) onto the outer surface. The reversible wetting properties of both surfaces impart the fabric with excellent moisture and thermal management capabilities. The treated fabric reduces skin temperature by approximately 5.0 °C within 8 min when worn at 31.0 °C and increases skin temperature by around 3.0 °C–4.0 °C within 8 min when worn at 9.5 °C. This fabric, capable of rapidly managing moisture and thermal conditions in a short duration, exhibits considerable potential for application in harsh and demanding environments.

Integrating personal thermoregulation technologies into wearable textiles has enabled extensive and profound technological breakthroughs in energy savings, thermal comfort, wearable electronics, intelligent fabrics, and so forth. Nevertheless, previous studies have suffered from long-standing issues such as limited working temperature, poor comfort, and weak reliability of the textiles. Here, we demonstrate a skin-friendly personal insulation textile and a thermoregulation textile that can perform both passive heating and cooling using the same piece of textile with zero energy input. The insulation textile material is composed of biomaterial microstructured fibers that exhibit good thermal insulation, low thermal emissivity, and good dyeability. By filling these microstructure fibers with biocompatible phase-change materials and coating them with polydimethylsiloxane, the insulation textile becomes a thermoregulation textile that shows good water hydrophobicity, high mechanical robustness, and high working stability. The proposed thermoregulation textile exhibits slow heating/cooling rates with improved thermal comfort, offering feasible and adaptive options for personal cooling/heating scenarios and enabling scalable manufacturing for practical applications.

Silk fabric (SF) is a high-end textile frequently utilized in summer apparel. However, its ultraviolet absorption reduces the solar energy reflection, and the inherent hydrophilicity impedes effective sweat evaporation, thereby significantly compromising thermal-moisture comfort. Herein, we fabricated a multifunctional Janus SF with rapid heat dissipation, unidirectional moisture conduction and radiative cooling capabilities through a feasible two-step process. Briefly, hydrophilic Al 2 O 3 nanoparticles were covalently anchored on the outer side (A-side) of Janus SF, whereas a hydrophobic boron nitride (BN) nanosheet-doped layer was fabricated on the inner side (B-side) via polycondensation reaction. The optimized Janus SF demonstrated exceptional solar reflectivity (93.62 %) and infrared emissivity (92.08 %), alongside enhanced thermal conductivities (1.45 W/K/m in-plane and 0.182 W/K/m through-plane). Additionally, the wettability gradient between the hydrophilic A-side and hydrophobic B-side provided a robust driving force for moisture transport, endowing Janus SF with a distinguished unidirectional transportation index of 809.43 % and a satisfactory water evaporation rate of 88.49 g/(m 2 ·h), thereby ensuring prolonged thermal-moisture comfort. Notably, this Janus fabric displayed remarkable outdoor practical cooling effect (∼5.6 °C) compared to bare skin, accompanying with good biocompatibility and outstanding wearability. Overall, such durable, scalable and multifunctional Janus SF provides innovative inspiration for designing next-generation passive cooling fabrics.

Facing the serious problem of rapidly increasing myopia rate, the demand for eyeglasses is increasing, while the traditional manufacturing methods for eyeglass frames and lenses are long, slow, and expensive. In this article, we propose to fabricate myopia glasses by 3D printing method, and the frames and lenses are produced by digital light processing and stereo lithography appearance methods, respectively. Through the tensile and elongation at break test, it shows that the mechanical properties of the 3D printed frames are good, and the mechanical collision simulation results show that it does not affect the normal use under the impact of large speeds, which shows a high degree of uniformity with the mechanical experiments; through the pressure test at different positions after wearing, it verifies the wearing comfort of the myopic frames; after polishing the printed myopic lenses, through the optical experiments, it shows that the transmission rate of the myopic lens is comparable to that of the traditional glasses. The transmission rate has been more similar to the traditional glasses; measurement of the refraction of the printed myopic lenses compared with the theory, the error is within the acceptable range. Through the wearing test, it shows that the 3D-printed myopic lenses have a certain corrective effect on visual acuity.

Frequent outbreaks of emerging infectious diseases (EIDs) make personal protective filter media in high demand. Electrospun nanofibrous materials are proved to be very effective in resisting virus-containing fine particles owing to their small fiber diameters; however, hindered by the intrinsic close-packing character of fine fibers, electrospun filters suffer from a relatively high air resistance, thereby poor breathing comfort. Here, we report a biomimetic and one-step strategy to create ultrafine and curly wool-like nanofibers, named nano-wool, which exhibit fluffy assembly architecture and powerful electret effect. By achieving the online self-crimp and in-situ charging of nanofibers, the curly electret nano-wool shows a small diameter of ~0.6 μm (two orders of magnitude lower than natural wool: ~20 μm) and an ultrahigh porosity of 98.7% simultaneously, together with an ultrahigh surface potential of 13260 V (one order of magnitude higher than previous filters). The structural advantages and powerful electret effect enable nano-wool to show excellent filtration efficacy (>99.995% for PM 0.3 ) and low air resistance (55 Pa). Additionally, nano-wool can be easily scaled up, not only holding great industrial prospect in personal protective respirators, but also paving the way for developing next-generation wool in a cost-efficient and multifunctional form.

Wearable thermoelectric generators provide a reliable power generation method for self-powered wearable electronic devices. However, there has been a lack of research regarding the comfort of wearable thermoelectric generators. Here we propose a design for a comfortable wearable thermoelectric generators system with high output power based on sandwiched thermoelectric model. This model paves the way for simultaneously optimizing comfort (skin temperature and pressure perception) and output power by systematically considering a variety of thermal resistive environments and bending states, the properties of the thermoelectric and encapsulation materials, and the device structure. To verify this strategy, we fabricate wearable thermoelectric generators using Mg-based thermoelectric materials. These materials have great potential for replacing traditional Bi 2 Te 3 -based materials and enable our wearable thermoelectric generators with a power density of 18.4 μWcm −2 under a wearing pressure of 0.8 kPa and with a skin temperature of 33 °C, ensuring the wearer’s comfort.

Human thermal management technologies based on radiant cooling can achieve portable, lightweight, long-lasting, and zero-energy cooling. However, in a high-temperature environment, perspiration continues to accumulate and increased humidity reduces the efficiency of radiant cooling, thus affecting human thermal and humidity comfort. Therefore, we developed a radiation-cooled aerogel film with easily tunable pore sizes consisting of cellulose acetate, polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP), and aluminum oxide (Al2O3), which has excellent optical properties, moisture permeability, and thermal stability. The appropriate pore size distribution and porosity not only enhance the solar reflectivity of the film but also improve its surface wettability. High solar reflectance (R̅solar = 97.4%) and infrared emissivity (ε̅IR = 98.5%) enabled the film to produce subambient cooling of 8.1 °C at an irradiance of 794.1 W/m2. Furthermore, even under conditions of high humidity (relative humidity = 90%), the film is expected to achieve a maximum daytime cooling power of 57 W/m2. The aerogel film exhibited superior moisture permeability (WVT = 7224 g/m2·24 h) compared to commercial cotton fabric. This work has significant applications in the management of human heat and humidity in extreme heat environments.

Enhanced capabilities of stain removal and comfort control are simultaneously achieved by the light and thermo dual-responsive copolymer poly(triethylene glycol methyl ether methacrylate-co-ethylene glycol methacrylate-co-acrylamide azobenzene) (P(MEO3MA-co-EGMA-co-AAAB)) cross-linked on cotton fabrics. P(MEO3MA-co-EGMA-co-AAAB) is synthesized by sequential atom transfer radical polymerization with a molar ratio of 8 (MEO3MA):1 (EGMA):1 (AAAB). The MEO3MA units induce a thermoresponsive behavior to the copolymer. The hydrophilicity of the copolymer films can be further improved by the light-induced trans–cis isomerization of the AAAB units with UV radiation. The copolymer is facilely immobilized onto cotton fabrics with 1,2,3,4-butane tetracarboxylic acid as cross-linker. Due to the immobilization of P(MEO3MA-co-EGMA-co-AAAB), the hydrophilicity of the fabric surface is increased under UV radiation. Therefore, by simply installing a UV light source in the washing machine, better capability of stain removal is realized for the cross-linked cotton fabrics. It can prominently reduce the consumption of energy, water, and surfactants in laundry. In addition, the trans-AAAB units of the copolymer cause the cross-linked P(MEO3MA-co-EGMA-co-AAAB) layer to be more hydrophobic under ambient conditions. Hence, the copolymer can more easily collapse and form a porous structure on the fabrics. Thus, the air permeability of cotton fabrics cross-linked with P(MEO3MA-co-EGMA-co-AAAB) is enhanced by 13% at human body temperature as compared to P(MEO3MA-co-EGMA), giving improved comfort control during daily wear.

Superhydrophobic durability of cotton fabric faces a great challenge due to the repeated washing and rubbing. The commercial pad-dry process method using polymer binders usually leads to wastewater discharge and the reduced wearing comfort. Herein, the superhydrophobic cotton fabric with strong durability was fabricated by a facile spraying method which did not produce any wastewater and can make efficient use of modifiers. The dopamine and 2-tetraethoxysilane can in-situ react to construct rough surface structure. The hexadecyltrimethoxysilane with long chain alkyl was firmly connected to cotton fiber surfaces to reduce the surface energy. The prepared sample not only obtained excellent superhydrophobicity with a water contact angle of 157 ± 1.2° and a shedding angle of 7.8 ± 0.3°, but also retained the inherent air permeability and hand feeling of cotton fabrics. Due to the strong covalent bonds between modifiers and cotton fibers, the modified cotton fabric exhibited high multiple mechanical durability and chemical stability in acid/base solution. The superhydrophobic cotton fabric showed a satisfactory self-cleaning performance toward the common stains in daily life. In addition, the modified fabric can serve as a separation filter for oil/water separation with high separation efficiency and reusability. This facile and clean preparation method showed great potential in large-scale production of durable superhydrophobic textile.
