Reactive oxygen species (ROS), as key mediators in the process of oxidative stress, can cause severe damage to body tissues when their excessive accumulation occurs. Therefore, exploring efficient antioxidant strategies has become an urgent task in medical and scientific research. Currently, numerous. Studies have shown that selenium nanoparticles (SeNPs) can efficiently scavenge excessive ROS in the body, demonstrating great application potential in the field of antioxidant therapy. At the same time, the in situ thermosensitive hydrogel drug delivery system has gradually occupied an important position in the field of drug delivery due to its thermosensitivity and injectability. Based on the above research results, we have developed an innovative in situ injectable thermosensitive hydrogel system—F127/HA‐SeNPs. This system combines F127 and hyaluronic acid as stable and efficient carriers, successfully loading SeNPs with strong antioxidant efficacy. This hydrogel exhibits thermosensitivity, injectability, adhesiveness, excellent biocompatibility, and antioxidant properties. Most importantly, relying on the loaded SeNPs, this hydrogel system exhibits a powerful and continuously stable ROS scavenging ability, effectively protecting cells from oxidative stress damage and improving mitochondrial dysfunction, thereby providing a practical and highly promising treatment solution for oxidative stress‐related diseases. Its material properties and functional mechanisms endow it with good application value and development prospects during the process of disease intervention.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147896396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This dual grafting process significantly enhanced the cationic degree of CS by introducing a higher density of N + (CH 3 ) 3 groups. Subsequently, HTCC‐BHC was incorporated into room temperature–vulcanized silicone rubber (RTV) via a solution blending approach, yielding HTCC‐BHC/RTV composites (HB‐RTV). To investigate its structure and properties, the composites were characterized by SEM, XRD, FTIR, 13 C NMR, DSC, rotational rheological analysis, and mechanical testing. The results indicated that increasing HTCC‐BHC content significantly improved the surface roughness, amorphous characteristics, crosslinking density, and mechanical properties of HB‐RTV. Molecular dynamics (MD) simulations and mean square displacement (MSD) calculations confirmed strong intermolecular interactions between HTCC‐BHC and RTV, reducing polymer chain mobility. Antibacterial assays revealed that HB‐RTV exhibited an inhibition rate of up to 99.99% against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ), with superior efficacy against E. coli . This was attributed to strong electrostatic interactions between the N + (CH 3 ) 3 groups in HTCC‐BHC and bacterial cell wall components, such as lipopolysaccharides and peptidoglycans. SEM and molecular docking further revealed that HB‐RTV exerted its bactericidal effect by disrupting bacterial cell membrane integrity and inducing cytoplasmic leakage. Thereby, the enhanced antibacterial efficacy contributes to improved preservation of fresh meat. This study provides a novel strategy for developing non‐toxic, highly antibacterial silicone rubber, establishing a theoretical and practical foundation for its applications in biomedical and packaging fields.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pat.70444","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cellulose‐based aerogel has outstanding thermal insulation properties, but the flammability of cellulose limits its application. Therefore, it is of great significance to give cellulose aerogel flame retardancy. This study presents a simplified and efficient method for preparing flame‐retardant cellulose aerogels through the dissolution of cellulose in a NaOH, ZnO, and urea solution, followed by freeze‐drying and in situ modification with boric acid. The resulting aerogels were extensively characterized to evaluate their morphology, mechanical performance, and flame‐retardant properties. The incorporation of urea and boric acid significantly enhanced flame retardancy, achieving Limiting Oxygen Index (LOI) values exceeding 80% and V‐0 ratings in the UL‐94 vertical burning test. Additionally, the modified aerogels demonstrated superior self‐extinguishing capabilities and improved mechanical strength. Thermal degradation analysis using TG‐FTIR revealed that the formation of a protective glassy layer of borax, along with the release of CO 2 and NH 3 gases, effectively suppressed combustion and delayed cellulose pyrolysis. Overall, this study demonstrates that the in situ formation of flame retardants in cellulose aerogels can markedly enhance fire resistance while preserving structural integrity, offering a promising approach for developing high‐performance materials.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the average particle size and absolute Zeta potential (| ζ |) of the cyclic carbonate emulsion obtained by choosing 2‐sulfamic acid were the smallest. The flexibility, adhesion and pencil hardness of the cured film became better. Compared with the solvent‐based NIPU film prepared with PGC, the pencil hardness (F) of the WNIPU film cured with isophorone diamine (IPDA) was higher while the impact resistance (40 cm kg) and adhesion of the WNIPU film cured with polyethylenimide (PEI‐300) were more excellent, and the shear strength (6.25 MPa) and peel strength (1.54 kN m −1 ) on the board were better than those of solvent‐based NIPU, which can be used as an adhesive.

To address this, we developed a green concentration strategy using superabsorbent polymer (SAP) beads. This method simultaneously absorbed water and selectively removed NRCs from RSL. After a single treatment, the total solids content of the concentrated latex increased to 37.24%, while the NRCs content was significantly reduced to 5.21%. This reduction in NRCs altered the polymer network, leading to a remarkable tensile strength of 22.39 MPa in the vulcanized films.

Microbial enhanced oil recovery (MEOR), with its sustainability and environmental friendliness, continues to hold a pivotal position.

By leveraging the hydrogel properties of sodium alginate (SA) and the oil solubility of lecithin, the composite material encapsulates microorganisms and is fabricated into microspheres. These microspheres are applicable for reducing the chemical oxygen demand (COD) in oilfield wastewater and decreasing the viscosity of heavy oil, thereby enhancing heavy oil recovery. Positive experimental results indicate that the inoculation of Bacillus subtilis is most efficient at 5%–7%, with an optimal pH range of 6.5–7.0, salinity not exceeding 5000 ppm, and a temperature around 40°C. COD reduction experiments reveal that with SA/L hydrogel microspheres, a mere 5% inoculation rate can achieve a reduction exceeding 60%, and a 7% inoculation rate can surpass 80%. Viscosity reduction experiments for heavy oil demonstrate that with SA/L hydrogel microspheres, a 5% inoculation rate can achieve a viscosity reduction rate of up to 81.6%, with the greatest reduction in saturated hydrocarbons followed by aromatic hydrocarbons.

However, it poses a potential risk of thermal damage to adjacent normal tissues, resulting in adverse consequences such as tissue carbonization and anastomotic necrosis. In this study, a conductive polyacrylamide‐alginate‐calcium ion (denoted as PAM‐ALG‐Ca 2+ ) hydrogel was developed as a cooling agent to reduce thermal damage. The PAM‐ALG‐0.5Ca 2+ hydrogel exhibited a maximum compressive strength of 4.78 ± 0.66 MPa, which is 36.77 times higher than that of the PAM‐ALG hydrogel. In addition, the hydrogel possessed an electrical conductivity of 15.46 S/m, a high‐water content of 85.90% ± 0.10% and notable biocompatibility with the mouse fibroblast cell line L929. The heat‐absorption performance of the hydrogel was also investigated through an ex vivo experiment, indicating that the heat‐absorption rate of the hydrogel (4.76 ± 0.17°C/min) was higher than that of the PAM‐ALG solution (4.38 ± 0.13°C/min) but lower than that of the 0.9% NaCl solution (5.57 ± 0.19°C/min). Furthermore, the tissue fusion experiment demonstrated that the fusion temperature was effectively reduced from 143.05°C ± 4.35°C to 105.10°C ± 1.8°C after the application of the hydrogel, meeting the requirements for clinical application. In addition, the fused tissues exhibited reduced thermal damage, better structural retention, and improved histological appearance.

However, its susceptibility to friction‐induced wear, which disrupts the surface nano‐microstructures and erodes hydrophobicity, severely curtails its practical utility. Silicon carbide (SiC) has been recognized for its ability to enhance polymer abrasion resistance and acid–alkali corrosion resistance. In this study, a novel approach was adopted to synthesize hydrophobic SiC by grafting perfluorooctyltriethoxysilane (PFOTS) onto nano‐SiC via chemical grafting. The resulting modified SiC was then integrated with TPU to formulate an F‐SiC/TPU composite coating, which was applied to aramid fabrics using a knife‐coating technique. The coated fabrics demonstrated remarkable superhydrophobicity, registering a water contact angle of 161°. Notably, the hydrophobicity endured even after rigorous sandpaper abrasion and tape‐peeling tests. Additionally, the coating remained stable following 12‐h immersion in highly corrosive media, such as 98% concentrated sulfuric acid and 40% sodium hydroxide solutions. In terms of anti‐stab performance, the static anti‐stab force of the coated fabrics surged from 42.51 N to 71 N, the anti‐cone stab force escalated from 33.12 N to 215 N, and the bursting strength soared from 205.34 N to 960 N. The composite material demonstrates unique advantages in complex environments with coexisting moisture, chemical corrosion, and physical impact, indicating that the developed F‐SiC/TPU composite‐coated aramid fabric exhibits remarkable potential in protective performance.

While adhesive bonding is commonly employed to fabricate SAM‐SIM composites, this approach carries inherent risks of interfacial failure. To enhance structural stability, a method combining vacuum impregnation and polymer curing at the bottom of porous sound‐absorbing materials is proposed to obtain a double‐layer SAM‐SIM structure. In this study, graphene oxide (GO) modified melamine (MA) sponge synthesized by freeze drying served dual roles: as the SAM layer and as a component in the SIM layer. High‐damping polyurethane (PU) was used as the polymer matrix in the SIM layer. GO content in the MA sponge and PU composites was modulated by adjusting the GO solution concentration. Sound absorption performance of GO/MA, as well as mechanical, damping and sound insulation performance of GO/MA/PU were studied systematically. Results indicate that GO improved the sound absorption performance of GO/MA and significantly improved the damping properties of GO/MA/PU composites. The double‐layer structure with 12.5 mm thickness of SAM and 2.5 mm thickness of SIM derived from GO/MA composite sponge treated with 5 mg/mL GO solution possessed average sound absorption coefficient (SAC) of 0.547 and average transmission loss (TL) of 41.88 dB in the frequency range from 1000 to 6300 Hz.
