Ionically conductive and liquid-free elastomers have gained recognition as promising candidates, addressing the challenges of evaporation and leakage in gel-based conductors. In this study, a sustainable polymeric deep eutectic system is synergistically integrated with amino-terminated hyperbranched polyamide-modified fibers and aluminum ions, forming a conductive supramolecular network with significant improvements in mechanical performance. The elastomer exhibits remarkable tensile strength (6.69 MPa) and ultrahigh toughness (275.7 MJ/m3), capable of lifting loads 8300 times its own weight and demonstrated notch-insensitive properties. The elastomer also possessed degradable and stepwise recyclable properties, supporting its sustainability. Its excellent mechanical performance and conductivity enable stable signal output for multifunctional electronics. A wearable strain sensor is developed, demonstrating high sensitivity (gauge factor up to 4.52) and reliable repeatability under strain. Furthermore, a durable triboelectric nanogenerator is also fabricated, delivering stable signal output over one month and demonstrating strong potential for tactile sensing across various contact materials, making it highly promising for future human–machine interaction applications.

Yet, one formidable issue of homogeneous FLP catalysts is their instability on preservation and recycling. Here we contribute a general solution that marries the polyhedral oligomeric silsesquioxane (POSS) with a structurally specific frustrated Lewis acid to fabricate porous polymer networks, which can form in situ water-insensitive heterogeneous FLP catalysts upon employing Lewis base substrates. The excellent resistance to water derives from the synergy of superhydrophobicity of silsesquioxane cage and the multiscale micro/nano-structural effect of formed porous networks. Using CO2 as a C1 feedstock, the FLP-POSS hybrid materials allow for the catalytically conversion of a variety of diamine substrates into the medicinal benzimidazole derivatives. Not only can the FLP units be immobilized on the networks meeting the needs of recyclable utilization but, more importantly, the materials are also of high catalytic efficiency and capable of working at near ambient CO2 condition owing to their favorable CO2 selectivity. Given that this organic/inorganic hybrid FLP catalyst features low cost, ease of synthesis, and little requirements on internal structural ordering, it will pave the way for large-scale preparation of amorphous heterogeneous FLP materials toward low-cost, robust, and sustainable C1 conversion.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"58 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its broader applicability is constrained by poor oil resistance and a suboptimal slip performance. In this study, we developed an SR with durable oil resistance and enhanced slip properties by forming a covalently bonded barrier layer on its surface through a one-step in situ fluorination reaction using F2/N2. The fluorination process exploration revealed that low concentrations of F2 preferentially produce thermodynamic products containing Si–F bonds, while higher F2 concentrations favor the formation of C–F bonds and Si–F bonds with similar contents in the surface layer, as confirmed by theoretical simulations. This fluorine-containing surface modification significantly reduces the friction coefficient from 0.68 to 0.38 and imparts fascinating amphiphobic properties, increasing water and oil contact angles by 31.7 and 23.2°, respectively, compared to pristine SR. As a result, the fluorinated SR demonstrates superior slip performance and enhanced stain resistance, particularly against challenging contaminants like chili oil, even after frictional wear owing to the robustness of the covalently bonded surface layer. Additionally, the outstanding oil barrier properties of the fluorinated SR confer excellent antibacterial performance against Escherichia coli and Staphylococcus aureus, positioning it as a highly promising material for everyday wearable applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"38 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One effective strategy to enhance the output capacity of NGs is to modulate the piezoelectric performance of the textiles. This paper focuses on further improving the piezoelectric properties of nylon-11,11 textiles through post-drawing and annealing treatments. We elucidate the evolution of morphology and the ferroelectric phase in the submicron/nanoscale fibers during post processing as well as the corresponding changes in performance. The drawing process primarily enhances the orientation of the crystalline phase and reduces the fiber diameter, while the annealing process more effectively promotes the crystal size and crystallinity. Afterward, we propose an optimal postdrawing and annealing assisted-electrostatic spinning process. Under the synergistic effects of these post-treatments, the remanent polarization (Pr) of nylon-11,11 textile increased to 4.7 times that of the untreated textile, resulting in amplified piezoelectric outputs. The output voltage, current, and power density of the prepared PENG reached 21.5 V, 800 nA, and 1.88 mW·m–2 (80 MΩ), respectively. Notably, at pressures exceeding 8 kPa, the mechano-voltage and current sensitivity reached as high as 266 mV/kPa and 13.99 nA/kPa, respectively, which is extraordinary compared to other piezoelectric NGs and comparable to the performance of nylon-based triboelectric NGs. Furthermore, we investigated the potential application of the prepared PENG in biomechanical energy harvesting and human movement monitoring. Experiments demonstrated its effectiveness in powering light bulbs, tracking walking status, and monitoring finger/hand/wrist gestures.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"25 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces fluorine-doped activated carbon adsorbents, where elemental fluorine incorporation into the carbon matrix plays a unique role in achieving high ethane selectivity. This enhanced selectivity arises from specific interactions between surface-doped fluorine atoms and ethane molecules, coupled with porosity modulation. Consequently, an equilibrium ethane/ethylene selectivity of as high as 3.9 at 298 K and 1 bar was achieved. Furthermore, polymer-grade ethylene (purity >99.99%) with a productivity of 1.6 mmol/g was obtained in a breakthrough run at ambient conditions from a binary ethane/ethylene (1/9 v/v) mixture. The ethane selectivity of the fluorine-doped carbons was further elucidated through Monte Carlo simulations and density contours of the adsorbed components. In addition to the high ethane selectivity, the adsorbents exhibited a hydrophobic surface, high stability under moisture, and excellent regenerability over multiple adsorption–desorption cycles under both equilibrium and dynamic conditions, demonstrating a sustainable performance.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"15 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This improvement is attributed to the electron-induced effect of boron doping, which also enhances the separation selectivity of CO2 from N2. Additionally, the high CO2 adsorption capacity fosters synergism between NBPCs and the cocatalyst tetrabutylammonium bromide (TBAB), thereby augmenting the catalytic activity for the cycloaddition of CO2 and epoxide. Notably, cyclic carbonate yields exceeding 99% were attained even under 1 bar of CO2. Controlled experiments corroborated the pivotal role of boron-doping-induced modifications in the porous carbon structure in enhancing both CO2 selective adsorption and conversion performance.

Here, a low-cost, high-concentration 26 m Li–B5–C15–O6 aqueous solution incorporating lithium bromide (LiBr), lithium chloride (LiCl), and lithium acetate (LiOAc) was developed for aqueous batteries, which demonstrated an expanded electrochemical stability window of ca. 2.5 V.

In-depth analysis using X-ray photoelectron spectroscopy and Raman spectroscopy revealed that the NAc host promoted the redox kinetics of active bromine species and improved the delivery capacity of the battery. Results revealed that the electrolyte in the NAc host achieved a discharge specific capacity exceeding 376 mA h g–1 while maintaining a capacity retention rate of up to 97% after 7800 cycles.
