However, poor durability of nanocoatings highlights the necessity of modifying the surface chemistry of fibers to maximize the adherence of nanomaterials. In this study, the surface of wool fibers was modified through the acylation process with succinic anhydride and then post-treatment with anatase TiO<sub>2</sub> colloid synthesized via the sol-gel method. Different aspects including the role of wool acylation on fibers chemistry, photostability, UV protection and antibacterial activity against <em>Escherichia coli (E. coli)</em> and <em>Staphylococcus aureus</em> (<em>S. aureus)</em> bacteria were discussed. Furthermore, wetting behavior, light and wash fastness, dyeability, and cytotoxicity of fabrics were investigated, and the role of each coating step was clarified. The findings confirmed that the modified fabric exhibited enhanced photostability under UVA radiation as tested using the photo-induced chemiluminescence (PICL) analysis. The functional fabric provided an excellent UPF level of 140, indicating 37 % improvement compared with pristine wool. The acylated fabric treated with TiO<sub>2</sub> colloid was hydrophilic and showed a washing fastness up to five accelerated wash cycles. The existence of TiO<sub>2</sub> led to a weaker color strength (K/S) on the dyed fabric, but did not photocatalytically affect the light fastness. The cytotoxicity test did not show any toxic effects on the examined cells viability. Moreover, comprehensive analyses using XPS, FTIR, SEM, and EDX mapping techniques were conducted to characterize the nano-treated fabrics. The outcomes of this research provide new insights on some less explored properties of functionalized textiles, paving the way for real-world applications.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"29 ","pages":"Article 100814"},"PeriodicalIF":8.7,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanoporous media with high sorption affinity and slow mass exchange can exhibit non-equilibrium adsorption behavior. Accordingly, this study introduces a species-based model incorporating non-equilibrium adsorption kinetics for binary gas transport within nanoporous media. The proposed model for the predictive transport of gases incorporates non-equilibrium adsorption, surface diffusion, and bulk, viscous, and Knudsen diffusion. The extended Langmuir rate equation covers non-equilibrium adsorption, while the generalized Maxwell-Stefan equation addresses surface diffusion. The model is validated against two different experiments and then applied to simulate CO<sub>2</sub> transport within methane-saturated nanoporous media, including organic-rich shales and coalbed methane. The simulation results reveal that the sorbed phase can occupy almost half of the pore volume. The comparison results between equilibrium and non-equilibrium adsorption models reveal that ignoring non-equilibrium sorption kinetics can lead to underestimating total mass flux and overestimating the sorbed-phase contribution of the mass flux. Using equilibrium adsorption can result in an underestimation of molar flux by 8%. The results of the molar flux ratio show that the sorbed phase adds three times more flux to the total flux when using the equilibrium adsorption model compared with the non-equilibrium adsorption model. This work demonstrates the impact of non-equilibrium adsorption on binary gas transport.
