Carbon fiber (CF) has been widely used in aerospace, military, infrastructure, sports, and leisure fields owing to its excellent mechanical properties, superior corrosion and friction resistances, excellent thermal stability, and lightweight. However, the ultrablack appearance derived from the extremely strong absorption of light throughout the entire visible region makes it difficult to satisfy the aesthetic and pleasurable demands of the colorful world and limits their applications in a broader field. Herein, inspired by the Japanese jewel beetle, a double-layer ultrathin Al2O3/TiO2 composite structure was fabricated on CFs by the atomic layer deposition method. CFs exhibited desired color diversity by controlling the thickness of Al2O3 and TiO2 films without changing the total thickness of the composite film’s structure. Meanwhile, colored CFs have no color change/destruction after a series of environmental durability measurements and exhibited remarkable superdurability and excellent flame retardancy. Our work provides insights for innovative, high-performance, and multifunctional CF that can help achieve high quality and sustainable development of the CF industry.

Incorporating zero-energy-input cooling-power generation technology into personal thermal management (PTM) systems is a promising solution for thermal energy utilization but remains a huge challenge due to lacking of effective assembly technology. In this work, a sustainable, cost-effective, superdurable, and nanostructured cellulosic metafabric (CWF) is reported that exhibits well radiative cooling function to achieve high-performance power generation. Through tailoring the viscoelasticity and optical performance in the electrospinning process, this metafabric demonstrates a unique micro/nano structure and anchored MOF assembly, 95.7 % solar reflectivity, 0.94 infrared emissivity, high mechanical strength, washability, surface hydrophobicity, and UV resistance can be achieved. This metafabric exhibited high cooling efficiency of 5.7 °C during direct sunlight in summer and anti-washing and UV stability. Furtherly, we coupled the CWF (as the cold sink) with a commercial thermoelectric device to assemble a power generation device. The device can output average voltage of 200 mV with an average temperature gradient of ≈20.1 °C under stimulated sunlight and shows superdurable power generation performance even after washing or folding (7000 cycles) use. An outdoor test demonstrated it can deliver a high output voltage of 519 mV in Nanjing, China. The cooling metafabirc shows great promise for practical applications in wearable power generation devices.

Developing material that can separate oil-water mixture and absorb spilled crude oil efficiently has become a pressing challenge. To this end, we prepared a polydopamine@octamine nano-capsules based superhydrophobic fabric with photothermal effect rapidly using UV-assisted preparation. The prepared superhydrophobic fabric exhibits excellent photothermal-induced oil absorption and oil-water separation performance. Not only oils with low viscosity can be absorbed efficiently, but also oils with high viscosity can be absorbed quickly. POS fabric could absorb crude oil up to 6.5 times of its own weight. The oil-water separation efficiency and flux could reach more than 98.8 % and 16,900 L·m −2 ·h −1 , respectively. Moreover, the separation efficiency remained unchanged even after 50 separation cycles while the separation flux rose gradually with the increase of oil-water separation cycle. Meanwhile, the as-prepared superhydrophobic fabric reveals outstanding durability and stability. It maintains superhydrophobic performance even after exposed to various harsh conditions such as acids, alkalis, salts, organic solvents, UV light, and mechanical abrasion. Additionally, the fabric has outstanding self-healing ability and which can extend its service life. Therefore, this simple, fast, and environment-friendly preparation method together with the excellent performance of resultant materials is expected to have broad application prospects in the treatment of oily wastewater and offshore crude oil spills.

Economic viability and durability are pivotal challenges limiting the commercial application of proton exchange membrane fuel cells (PEMFC). The development of low Pt usage oxygen reduction reaction catalysts with high catalytic activity and durability is imperative. Carbon support corrosion, as well as Pt particles agglomeration and exfoliation are primary causes of commercial Pt/C catalyst degradation. Here, a composite materials formed by TiO 2 containing oxygen vacancy (O V ) and carbon nanotube (CNT) was used as a functional support to successfully load Pt nanoparticles (NPs). The oxygen vacancy facilitated interactions between TiO 2 (O V ) and Pt, enhancing the anchoring of Pt NPs and suppressing particle growth. The Pt/TiO 2 (O V )-CNT demonstrates excellent performance with mass activity of 788 mA/mg Pt @0.85 V, the half-wave potential increased 34 mV and the tafel slope decreased by 11.89 mVdec −1 compared to commercial Pt/C. The durability of Pt/TiO 2 (O V )-CNT nearly 3-fold that of commercial Pt/C with negligible decay of half-wave potential (0.9 %) and mass activity (16 %). Density functional theory calculations and X-ray photoelectron spectroscopy indicated that the charge transfer from TiO 2 (O V ) to Pt facilitates the formation of strong metal-support interactions (SMSI), leading to a downward shift in the d-band center of Pt and a reduction in the binding strength to *OOH, thus lowering the activation energy of the rate-determining step which in turn promoting the activity of ORR. This study provides a reliable approach for designing catalysts with high activity and durability.

Pt-based alloy with high mass activity and durability is highly desired for proton exchange membrane fuel cells, yet a great challenge remains due to the high mass transport resistance near catalysts with lowering Pt loading. Herein, an extensible approach employing atomic layer deposition to accurately introduce a gas-phase metal precursor into platinum nanoparticles (NPs) pre-filled mesoporous channels is reported, achieved by controlling both the deposition site and quantity. Following the spatially confined alloying treatment, the prepared PtSn alloy catalyst within mesopores demonstrates a small size and homogeneous distribution (2.10 ± 0.53 nm). The membrane electrode assembly with mesoporous carbon-supported PtSn alloy catalyst achieves a high initial mass activity of 0.85 A mg Pt − 1 ${\mathrm{mg}}_{\mathrm{Pt}}^{-1}$ at 0.9 V, which is attributed to the smallest local oxygen transport resistance (3.68 S m −1 ) ever reported. The mass activity of the catalyst only decreases by 11% after 30000 cycles of accelerated durability test, representing superior full-cell durability among the reported Pt-based alloy catalysts. The enhanced activity and durability are attributed to the decreased adsorption energy of oxygen intermediates on Pt surface and the strong electronic interaction between Pt and Sn inhibiting Pt dissolution.

Effective strategy is intensively desired to construct efficient and durable catalytic system for mild aldol condensation between aldehydes, considering the profound significance in synthesis of high-valued α , β -unsaturated aldehydes. Although series of mild catalytic systems using secondary amine-based catalysts have been proposed, the compatibility of high catalytic selectivity and durability still troubles the researchers in this field. Here, we developed a protonated diethanolamine ionic liquid catalyzed mild aldol reaction system with reasonable regulation of ion pair strength and ionic cluster microenvironment based on the deep insights into proton shuttle effects to improve catalytic selectivity and durability for the probed methacrolein synthesis. The interplay between the cation and anion mediated proton shuttle was elucidated by detailed kinetics derived from in situ Raman spectroscopy and theoretical calculations. Further experimental and characterization facts combined with molecular dynamic simulations identify the weak interaction of cation–anion pair and metastable worm-like cluster microenvironment facilitate proton shuttle and thus improve catalytic performance and durability. Consequently, the formation rate of methacrolein was enhanced by one fold, while overall side reaction rates were reduced by 27.5% compared to the conventional sec -amine catalyst. Additionally, this strategy also exhibited significant promotion in catalytic activity, selectivity, and durability in synthesis of the other representative α , β -unsaturated aldehydes. These findings will offer reference for the construction and modulation of ionic liquid catalyzed mild aldol reaction system utilizing proton shuttle effects.

Superhydrophobic textiles have special applications in many fields such as medical treatment, military protection, oil–water separation, etc. In the large-scale pad–dry–cure process, a large number of polymer binders are often added to improve the superhydrophobic durability, resulting in a significant reduction in air permeability. To address this issue, a low-liquid atomization spray method was adopted to fabricate multi-durable superhydrophobic cotton fabrics using N1,N6-bis(2,3-epoxypropyl)hexane-1,6-diamine, a silica precursor, and fluorine-free hexadecyltrimethoxysilane as the main modifiers. The prepared fabric maintained excellent water repellency even after being subjected various harsh conditions tests such as 2000 cycles of friction, 40 washing cycles, ultrasonic treatment for 120 min, 200 tape peelings, and acid–alkali–salt corrosion for 24 h. The air permeability of the superhydrophobic fabric was measured to be 370.2 L m–2 s–1, which was merely 5% lower than that of the original fabric, indicating that the modified fabric retains satisfactory air permeability. The modified fabric exhibited an excellent self-cleaning effect with respect to various liquids. In addition, the prepared fabric showed good oil–water separation capability for both heavy and light oils. For heavy oil–water mixtures, the fabric sample exhibited a maintenance of 98.13% separation efficiency and a high flux of 18 032 L m–2 h–1 after 10 uses. These findings will help to promote the practical application of low-feed interface modification technology in the production of durable functional textiles.

The development of cotton fabrics with exceptional and durable fluorescent properties has garnered significant attention. In this study, an enduring fluorescence cotton fabric was fabricated by a convenient and efficient approach. Interestingly, carboxyl reactive groups were employed as bridging agents to covalently link the raw fabric with Europium (Eu)-based polyoxometalate, thus guaranteeing the tight bonds between the polyoxometalates and the fabric matrix. The morphology and microstructures of composite fabrics were characterized and compared, demonstrating the successful integration of polyoxometalates into the fabric featuring covalent bonding interactions. Additionally, the fluorescence emissions of composite fabrics were investigated ( λ ex = 243 nm). The emission spectrum exhibits typical emission peaks of Eu 3+ and polyoxometalate, corresponding to the 5 D 0 → 7 F 0–4 transitions in the range of 550–750 nm and the O → W transition, which results in distinct red fluorescence. Moreover, the lifetime-decay behavior, monitored at an excitation wavelength of 243 nm, follows a single-exponential function, yielding a lifetime ( τ ) of 0.4 ms. More importantly, owing to the robust interaction between the components, the composite fabric demonstrates exceptional fastness properties, including resistance to washing (50 times washing), abrasion (under both dry and wet conditions), and sunlight (9 days). In particular, three kinds of shaped masks were used, highlighting its potential as a reusable anti-counterfeiting material. The plausible mechanisms of the system is attributed to the efficient electron transition and energy transfer processes within the composite structure. Besides, mechanical property reveal PW 11 Eu@CF almost inherits the original fabric’s mechanical property. This work provides a novel strategy for the controlled design and fabrication of polyoxometalate-based anti-counterfeit material.

Polyacrylate was widely used in textiles, leather, and functional coatings due to its excellent film formation and flexibility. However, its durability was compromised by mechanical damage and poor water resistance. This study aimed to design a UV-induced self-healing polyacrylate coating (PXD) using vinyl-modified coumarin and acrylate monomers based on photoreversible covalent and hydrophobic interactions. The effect of the coumarin structure on the mechanical and self-healing properties was systematically examined. Results showed that increasing polymer chain flexibility, extending the distance between coumarin structures and the main chain, and raising the healing temperature enhanced self-healing efficiency. The PXD samples achieved over 84% healing efficiency after 8 h of 365 nm UV irradiation at 60°C, with scratches approximately 15 μm wide nearly fully healed within 2 h. Molecular dynamics simulations confirmed the influence of monomer structure on polymer flexibility, and the PXD self-healing mechanism was clarified. PXD-5 also exhibited improved hydrophobicity and water resistance, particularly under UV light, significantly enhancing leather durability. This development of UV-induced self-healing polyacrylate coatings represents a significant advancement in functional coating materials.

Flexible, lightweight, and durable electromagnetic interference (EMI) shielding materials are urgently required to solve the increasingly serious electromagnetic radiation pollution. Transition metal carbides/nitrides (MXenes) are promising candidates for EMI shielding materials because of their excellent metallic electrical conductivity . However, MXenes are highly susceptible to oxidization when exposed to wet environments, leading to the loss of their functional properties and degradation of reliability and stability. Herein, an interfused core–shell heterogeneous reduced graphene oxide (rGO)/MXene aerogel (GMA) is designed for the first time via coaxial wet spinning and freeze-drying. The fabricated GMAs exhibit excellent EMI shielding performance, and the EMI shielding effectiveness (SE) and specific EMI SE can be up to 83.3 dB and 3119 dB·cm 3 /g, respectively, which is higher than most carbon-based and MXene-based aerogels and foams. More importantly, GMAs have only a 17.4 % degradation in EMI shielding performance after 120 days due to the protection of hydrophobic graphene sheath, exhibiting superior EMI shielding durability to its MXene film counterpart. Moreover, the hydrophobic GMAs exhibit good oil/water separation and thermal insulation performance. The interfused core–shell GMAs are highly promising for applications in durable EMI shielding, thermal insulation, oil/water separation and sensors, etc.

Novel nanofibrous membranes with outstanding adsorption property and high durability were fabricated by chemically immobilizing carboxymethyl-β-cyclodextrin polymers on the surfaces of biodegradable poly((butylene succinate-co-terephthalate)-co-serinol terephthalate) nanofibrous membranes via the amidation reaction. As an ecofriendly adsorbent, the resulting nanofibrous membranes presented rapid adsorption toward methylene blue (MB) dye with a removal efficiency of about 90% within 30 s and had the maximum adsorption capacity of 1030.9 mg/g to it. The thermodynamic parameters indicated that the adsorption process of the adsorbent to MB dye was endothermic and spontaneous. Selective adsorption was another advantage to the adsorbent, which showed preferable adsorption to cationic dye MB rather than anionic dye methyl orange with a separation efficiency of 99.9% to them. Inspiringly, the removal efficiency and mechanical properties of the adsorbent hardly changed after 20 regeneration cycles, indicating its good regeneration and high durability in treating the dye-containing wastewater.

The surface treatment of fabrics in an atmospheric environment may pave the way for commercially viable plasma modifications of fibrous matters. In this paper, we demonstrate a durably superhydrophobic cotton cellulose fabric prepared in a single-step graft polymerization of hexamethyldisiloxane (HMDSO) by N2and O2atmospheric pressure plasma. We systematically investigated effects on contact angle (CA) and surface morphology of the cotton fabric under three operational parameters: precursor value; ionization gas flow rate; and plasma cycle time. Surface morphology, element composition, chemical structure and hydrophobic properties of the treated fabric were characterized by scanning electron microscope (SEM), EDS, FTIR and CA on the fabrics. The results indicated that a layer of thin film and nano-particles were evenly deposited on the cotton fibers, and graft polymerization occurred between cellulose and HMDSO. The fabric treated by O2plasma exhibited a higher CA of 162° than that treated by N2plasma which was about 149°. Furthermore, the CA of treated fabrics decreased only 0°~10° after storing at the ambient conditions for four months, and treated fabrics could also endure the standard textile laundering procedure in AATCC 61-2006 with minimum change. Therefore, this single-step plasma treatment method is shown to be a novel and environment-friendly way to make durable and superhydrophobic cotton fabrics.Keywords:atmospheric pressure plasma;durability;superhydrophobility;cotton fabric;siloxane
