However, the actual application environment is complex and changeable, and the failure of the material is a common problem in the use process. Fluorinated polyurethane acrylate was synthesized via the fluorinated unit alcohol end-capping approach to enhance the antioxidant capacity of gas separation membranes. The fluorine element is used as an important part of the membrane structure, and then the antioxidant capacity of the membrane is enhanced. Specifically, hexamethylene diisocyanate isocyanurate (HDI) trimer and 1H, 1H, 2H, 2H-Tridecafluorooctanol (TFOA) were precisely metered and underwent an addition reaction. Subsequently, two molecules of the resulting addition products were connected to a molecule of 1,6-hexanediol (HDO). This was followed by a nucleophilic addition reaction between hydroxyethyl methacrylate and the fluorine-rich molecular formula, yielding fluorinated polyurethane acrylate (FPUA). To fabricate the gas separation membrane, photoinitiators were incorporated into the FPUA, followed by curing under UV irradiation. Under optimized conditions, the membrane exhibited exceptional performance in CO₂/SF₆ separation, achieving a gas selectivity of 126.11. The presence of abundant carbon, fluorine, and oxygen atoms in the separation layer significantly bolstered its antioxidant properties. After immersion in a 1 g/L NaClO solution for 7 days, the membrane exhibited minimal corrosion loss of only 1.5% ± 1.3%, and the water contact angle decreased by just 1.8°. This robust membrane material offers promise for the separation of mixed gases containing oxidizing components.</p>\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 20","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional H₂S sensors often suffer from external circuits, measurement systems, liquid-phase reactions, or high detection limits. Herein, a colorimetric sensor for H₂S detection was developed by incorporating colorimetric dye [lead acetate, Pb(OAc)₂] into polyacrylamide (PAM)/polyvinyl alcohol (PVA) hydrogel. Benefitting from the interpenetrating polymer network, non-covalent interactions such as hydrogen bonds and dense internal structure, the hydrogel exhibited excellent adhesion to different substances (adhesion strength up to 14.11 kPa) and mechanical properties (tensile strength up to 116.92 kPa, elongation rate up to 576%). Furthermore, due to the liquid-phase reaction system and excellent [Pb(OAc)₂] loading capacity provided by the hydrogel, the prepared sensors exhibited excellent sensing performance response time, sensitivity, and simplicity. The theoretical detection limit of the sensor was 0.69 ppm, and the minimum exposure time required for detection was 14 s. The colorimetric effect of the hydrogels was positively correlated with the addition of Pb(OAc)₂ and the extension of time. The results showed that the color change of PAM/PVA/Pb(OAc)₂ hydrogel can be visible to the naked eye even if the concentration of H₂S is only 1 ppm. It is expected that this hands-free, arbitrarily adhesive, stretchable hydrogel colorimetric sensor strategy for visual detection of H₂S will extend toxic gas alarm systems to a new level.</p>\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 18","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are distinguished by their superior power density and exceptional stability over numerous cycles. However, their energy density is still rather low compared to other available options, and this is a significant deterrent to their use. Some of the recent works have shown that integrating electric double-layer capacitance with pseudo-capacitance can greatly improve the energy density of such systems. To this end, the hypercrosslinked polynaphthalene-based polymer was used to synthesize the microporous carbon through the process of chemical activation, and the material was named MONC-800-2. Then, cobalt acetylacetonate was used to introduce Co into the carbon matrix using the hydrothermal method to synthesize Co-doped hypercrosslinked polynaphthalene-based microporous carbon, namely MONC-800-2@Co-1-190. This material was revealed to have high microporosity and proper pore size distribution. The integration of cobalt within the electrode material of supercapacitors successfully combines the features of electric double-layer capacitors and pseudo-capacitive mechanisms, yielding a specific capacitance of 363.8 F g⁻¹ at a charging current density of 1.0 A g⁻¹. Employed within a hybrid supercapacitor system, this setup achieved an energy density of 16.13 Wh kg⁻¹ and a power density of 750 W kg⁻¹. After enduring 5000 charge–discharge cycles under a steady current, the system preserved 82.85% of its initial capacitance while maintaining a coulombic efficiency of approximately 99.99%, thereby demonstrating its excellent cycling stability and high coulombic efficiency.

In this research, polysulfone hollow fibers (PSF) modified by silicone rubber coating (PDMS) loaded with hydrophobic silica nanoparticles (SiO₂) were studied as membrane contactors in order to dehumidify the feed gas using diethylene glycol (DEG) as the sorbent liquid. The study aimed to evaluate how the addition of nanoparticles influenced the membrane's structure, hydrophobicity, roughness, and separation performance, particularly flux and efficiency. Findings revealed that surface modification raised the contact angle pressure of water and DEG from 72° to 154° and 58° to 127°, respectively, and enhanced the liquid entry pressure of water and DEG from 6.1 to &gt; 10 bar and 3.7 to 6 bar, respectively. The effect of liquid velocity on water vapor absorption flux was minimal, indicating no mass transfer resistance in the liquid phase. However, increased gas phase velocity significantly improved absorption flux and efficiency. Initially, the neat membrane had a higher absorption flux due to its effective porosity, but its performance dropped over time, failing by day 20. The results of the stability test demonstrated that a wetting ratio ranging from 1% to 2%, achieved after 11 to 16 days, led to a reduction in flux by 30% to 55%. Conversely, the optimum silicone rubber-coated membrane loaded with silica nanoparticles maintained a wetting ratio under 1% and showed more stable flux with respect to the reference membrane for 42 days (a 6 weeks test) due to enhanced surface characteristics. The optimum membrane depicted a flux of 1.8 × 10⁻² mol/m² s, which is 1 to 2 orders of magnitude higher than the previous studies. It was anticipated that, by modifying the surface properties of the contact membrane, the long-term performance of the contact membrane would be enhanced to have a significant growth compared to the pure membrane and the open literature reports.
