Superhydrophobic surfaces have been extensively used in antifouling, energy storage, metal corrosion and oil-water separation. However, problems caused by using organic solvents in the preparation process and poor durability still limited its application. In this paper, a kind of durable superhydrophobic (water contact angle>156°, sliding angle <10°) and superoleophilic fabrics have been fabricated based on a waterborne solution using polydimethylsiloxane, fluorosurfactant as low surface energy substances. The superhydrophobic performance of fabrics show intelligent self-healing property after plasma treatment, abrasion and machine washing for 10, 1000 and 100 cycles, respectively. Besides, the coated cotton fibers also exhibit excellent durability and long-term stability under extreme acidic/basic conditions.

Recently, the Ti 3 C 2 T x MXene-based flexible electronics have sparked wide attention in artificial health diagnosis, military security and human–machine interaction. High sensitivity, durability and multifunctionality are desired for strain sensors in long-term health detection. However, unevenness and low fastness of MXene and stretchable nanofibers lead to poor sensitivity and durability, building a strong interface to combine the two-dimensional (2D) MXene nanosheets uniformly along the 1D nanofibers and form a 3D connected electrical network benefits to the improvement of sensing performances. Herein, we propose a facile strategy to prepare a breathable and multifunctional all-nanofiber sensor based on MXene and styrene–butadiene–styrene (SBS) nanofibers. Firstly, the molecular chain of SBS introduces quaternary ammonium groups (NSBS) by thiol-ene click chemistry, hydrophilicity and mechanical properties of NSBS nanofibers are significantly improved, then MXene nanosheets can uniformly and firmly adsorb along with NSBS nanofibers by electrostatic interaction. The assembled MXene/NSBS sensor reaches an ultrahigh sensitivity of 62,194 in the wide detection range of 300% and stability over 3000 cycles for human joint motion, pulse and ECG signal wireless detection. Furthermore, the MXene/NSBS electrodes demonstrate temperature response and thermal management performance including Joule heating and photothermal performance. Consequently, this work indicates a promising candidate for real-time health diagnosis and artificial intelligence in next-generation multifunctional devices.

Functional surfaces with superhydrophobic and superoleophobic properties are of great interest in many applications. However, such surfaces are generally difficult to obtain. Although a few superamphiphobic surfaces have been developed recently, a challenge still remains in preparing such a surface with good durability which is a critical issue in practical application. In this study, we demonstrate a facile method for preparing durable superhydrophobic and highly oleophobic surfaces using two kinds of nanoparticles. Epoxy resin is used as the adhesive material to improve the wear resistance of the surfaces. ZnO nanoparticles and SiO2 nanoparticles are used to create high surface roughness. The prepared surfaces exhibit excellent superhydrophobicity and high oleophobicity once the nanoparticles are treated with 1H,1H,2H,2H-perfluorodecyltriethoxydsilane (FAS-17). Water and ethylene glycol contact angles of the coatings can reach up to 172 ? 2? and 157 ? 2?, respectively. After undergoing strong adhesive tape peeling and mechanical abrasion, the coatings still maintain good amphiphobicity.

The limited robustness and complex preparation process greatly hinder the large-scale use of superhydrophobic surfaces in real life. In this work, we adopt a simple method to prepare robust fluorine-free superhydrophobic cotton fabrics by a facile dip-coating method based on silica microparticles and titanium dioxide nanoparticles. Microparticles and nanoparticles are used to build a suitable rough hierarchical structure, while strong bonds are formed between fabric and particles by a silane coupling agent. The cross-linking reaction between the isocyanate group of trimers of hexamethylene diisocyanate (HDI) and the hydroxyl group of each component in the condensation reaction further increases the bonding between the coating and the cotton fabric. In addition, polydimethylsiloxane (PDMS) is used as a low-surface-energy material to modify the fabric surface. The resulting coating shows excellent superhydrophobic properties with a water contact angle of 161.7°. Meanwhile, the prepared superhydrophobic fabric exhibits excellent durability and stability after sandpaper wearing, washing, and UV radiation, as well as treatment with various organic solutions, boiling water and different pH solutions. Moreover, the superhydrophobic fabric displays excellent UV protection performance and high oil–water separation efficiency (>99% after 30 cycles) with ultrahigh flux up to 20 850 L m−2 h−1.

In recent years, slippery liquid-infused porous surfaces (SLIPSs) have emerged as a potential alternative to superhydrophobic surfaces (SHSs) due to their exceptional anti-icing properties. However, the current challenge lies in the significant lubricant consumption of SLIPSs, which poses a major obstacle to coating durability. In this study, we developed a durable anti-icing coating with stability (DASS), which combines SHSs and SLIPSs. By incorporating high adsorption particles and low cross-linking density rubber into the oil storage layer, the coating achieves an increased oil storage capacity while effectively inhibiting lubricant loss. Additionally, a superhydrophobic layer is introduced on the surface to ensure surface lubrication and prevent lubricant depletion. The three-layer structure enables the coating to maintain a low τ ice (<20kPa) during 30 icing/deicing cycles, showcasing superior de-icing durability compared to conventional anti-icing coatings. Interestingly, the original anti-icing properties of the coating can be restored through external oil replenishment. Furthermore, this coating exhibits excellent resistance against fouling, mechanical stress, chemical exposure, temperature variations, and weathering effects, making it highly suitable for practical applications in anti-icing coatings.

Ions in seawater hinder direct sewage electrolysis due to the extreme corrosion of Cl − to the anode and reaction of Mg 2+ and Ca 2+ on the cathode producing solid substances, which reduce the electrolytic efficiency. However, traditional desalination consuming fossil fuel with massive CO 2 emissions threatens human survival. Therefore, zero-carbon emission, ultra-durable, large-scale production of freshwater from seawater for water electrolysis is urgently needed. Herein, a multifunctional system for seawater is demonstrated electrolysis based on ultra-durable solar desalination outdoors. The solar evaporators reach an evaporation flux of 1.88 kg m −2 h −1 with a photothermal conversion efficiency of solar energy as high as 91.3% with excellent ultra-durable salt resistance even for saturated saltwater due to the Marangoni effects. Moreover, the condensation of pure water from solar desalination based on the evaporation system reaches 0.54 L m −2 h −1 outdoors, which is suitable for a 20 cm × 20 cm engineered electrode equipped with a Janus membrane powered by a solar panel to produce H 2 outdoors. The ultrafast unidirectional transport of H 2 bubbles enabled by Janus membranes can greatly improve the H 2 production efficiency at a rate approaching 85 mL h −1 for continuous 24 h outdoors.

Long-term continuous monitoring (LTCM) of physiological electrical signals is an effective means for detecting several cardiovascular diseases. However, the integrated challenges of stable adhesion, low impedance, and robust durability under different skin conditions significantly hinder the application of flexible electrodes in LTCM. This paper proposes a structured electrode inspired by the treefrog web, comprising dispersed pillars at the bottom and asymmetric cone holes at the top. Attachment structures with a dispersed pillar improve the contact stability (adhesion increases 2.79/13.16 times in dry/wet conditions compared to an electrode without structure). Improved permeable duct structure provides high permeability (12 times compared to cotton). Due to high adhesion and permeability, the electrode's durability is 40 times larger than commercial Ag/AgCl electrodes. The treefrog web-like electrode has great advantages in permeability, adhesion, and durability, resulting in prospects for application in physiological electrical signal detection and a new design idea for LTCM wearable dry electrodes.

Photoluminescent fibers are widely used in smart textiles due to their excellent adaptability, flexibility, and energy-saving. However, the opaque matrix that may absorb the emitted light limits the color exhibition. Meanwhile, the insufficient stretchability and luminous stability hinder long-term practical applications. To solve the issues, a transparent polyurethane matrix is employed to design silicon nanocrystals-based photoluminescent fibers through continuous wet spinning. The polyurethane matrix possesses a high transparency of 89.1% at visible bands, facilitating the emission of silicon nanocrystals. The as-prepared photoluminescent fibers have a maximum stretchability of 1421.59% and high luminous stability within 365 days, which enables them to be arbitrarily weaved into functional textiles, and have long photoluminescence timeliness. The facile fabrication of luminescent silicon nanocrystals/polyurethane fibers may provide a groundbreaking strategy for realizing color-modulated functional wearables and flexible displays.

Micro-nano structures play a pivotal role in constructing superhydrophobic fabrics. However, the micro-nano structures, formed by hydrogen-bonding assembly of inorganic nanoparticles, are susceptible to falling off, making superhydrophobic fabrics nondurable during practical applications. To address this issue, chemical bonding is proposed to construct micro-nano structures on cellulosic fibers by reactive phenyl T 7 -POSS-OH. Subsequently, polydimethylsiloxane (PDMS) binder is further introduced on surfaces of cotton fibers by dip-coating. Astonishingly, the treated cotton fabrics exhibit impressive superhydrophobic stability under harsh conditions including immersion in acidic/alkaline media, or organic solvents, high-temperature and outdoor exposures. Interestingly, the as-fabricated cotton fabrics show outstanding thermal self-healing capability even if suffered from extreme treatments including mechanical abrasion, UV irradiation, laundering and air plasma etching. Most notably, mechanical strength of the modified fabric is improved by two times as compared to that of the pristine cotton fabric. Unfortunately, both air permeability and thermal stability of the modified cotton fabric are slightly weakened due to reactive POSS. Additionally, the modified cotton fabric also exhibits excellent stain resistance, self-cleaning ability and oil-water separation performance. These findings provide an instructive strategy for developing durable multifunctional cotton fabrics, envisioning promising application prospects in self-cleaning, oil-water separation and water-proof fields in the future.

To develop a durable superhydrophobic cotton fabric (CF) for effectively separating oil/water mixtures, a pyrogallol-based polybenzoxazine with abundant hydroxyl groups (PPG-D) and Fe 3 O 4 were adopted to decorate CF. Meanwhile, a commercial benzoxazine based on bisphenol A and aniline (BA-a) was also incorporated to enhance the application potential of superhydrophobic CF. As expected, a durable superhydrophobic cotton fabric (PPG-D@PBA-a@Fe 3 O 4 @CF) with a water contact angle (WCA) of 154° was successfully fabricated via a facile dip-coating method. PPG-D@PBA-a@Fe 3 O 4 @CF not only could effectively separate immiscible oil–water mixtures with a high permeation flux of up to 12207 L/m 2 h and separation efficiency of above 98.8%, but also displayed a satisfactory separation ability for surfactant-stabilized water-in-oil emulsions with a separation efficiency of over 99.8% and high flux in the range of 4971–8281 L/m 2 h, and the modified CF remained a superior separation efficiency and flux even after 20 separation cycles. In addition, PPG-D@PBA-a@Fe 3 O 4 @CF also displayed outstanding mechanical and chemical stability as well as excellent self-cleaning ability, and the WCA of modified CF could reach 148° even after 100 abrasion cycles. These excellent characteristics make PPG-D@PBA-a@Fe 3 O 4 @CF have a promising application in oil–water separation.

In this study, hydrophobic fabrics with controllable rough surfaces were prepared by treating a polyester (PET) fabric with methyltrichlorosilane (MTS), phenyltrichlorosilane (PTS), vinyltrichlorosilane (VTS), and tridecylfluorooctyltrichlorosilane (PFOTS) using a liquid phase method. The formation mechanism of the fabrics was investigated using X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy . Although the WCA of the fabrics decreased after mechanical abrasion, their hydrophobic surfaces exhibited good durability. Four controllable rough structures were observed and show its unique properties. MTS@PET showed a hollow spherical structure, and hence was found to have potential to encapsulate medicines for health care. On the other hand, PTS@PET showed a hollow bowl-like structure and strong absorbance to water. The TCS/PFOTS@PET with spherical microstructure was amphiphobic, according to that the contact angles of it to water and n -tetradecane were 153.3 ± 3.0° and 133.4 ± 4.5°, respectively. The WCA and sliding angle (SA) of VTS@PET, which showed a nanofilament structure, were 156.4 ± 3.0° and 3.0 ± 2.0°, respectively, indicating that its surface was superhydrophobic .

The application of titanium dioxide (TiO 2 ) photocatalyst in concrete is considered a promising method to effective remove nitrogen oxide (NOx) pollutants. However, the influences of application ways on photocatalytic efficiency and catalyst durability should be concerned in detail for its large-scale application. This paper compared the photocatalytic NOx degradation efficiency and durability of conventional TiO 2 powder dispersed in cement mortar (TPC), TiO 2 supported aggregates mounted on cement mortar surface (TAS) and TiO 2 supported aggregates dispersed in cement mortar (TAD), with considering different environmental factors effects such as gas flow rate, NO initial concentration and relative humidity. The photocatalytic efficiency results show that the NOx removal efficiency of TAS is about 1.5 and 1.1 times higher than that of TPC and TAD, respectively, corresponding to the utilization efficiency of TiO 2 photocatalysts in TAS is ca. 10 and 16 times higher than in TPC and TAD, respectively. The surface abrasion test suggests that TAS has relatively low photocatalytic efficiency compared with TAD after polishing the sample surface by more than 2 mm, which depends on the mounted thickness of TiO 2 supported aggregates. The findings in this work can provide the basis for the application ways of TiO 2 supported aggregates in concrete by considering its photocatalytic efficiency, economic efficiency and catalytic durability.
