However, their mechanical performance is inherently limited, and conventional drying techniques such as freeze-drying (FD) and supercritical drying (SCD) are both time-consuming and energy-intensive, posing significant challenges for large-scale industrial applications. Atmospheric pressure drying (APD) has emerged as a simple and cost-effective alternative, demonstrating considerable potential in the fabrication of aerogel fibers. In this study, chitosan was incorporated during the dissolution stage to reinforce the cellulose framework. Following solvent exchange, the material was subjected to APD in an oven, resulting in the fabrication of low-shrinkage chitosan-reinforced cellulose aerogel fibers (CKAF). The porosity of CKAF can be controlled between 38 and 75% by selecting solvents with different surface tensions for solvent exchange and adjusting the affinity between the solvent and the CKAF framework during APD. The shrinkage of atmospheric pressure drying chitosan-reinforced cellulose aerogel fibers (APD-CKAF) with a chitosan content of 10% to cellulose was 11%, which was only 1.9% higher than that of FD (9.1%). However, the pore structure of the APD-CKAF is compact and uniform, with a pore size distribution ranging from 0 to 48 nm, primarily centered around 20 nm, and a porosity of approximately 75%. The APD-CKAF exhibits superior mechanical strength (22.1 MPa, a 16.3% improvement over the FD samples) and elongation at break (55.1%, a 111.5% increase compared with the FD samples). The APD-CKAF exhibits excellent thermal insulation properties over a wide temperature range. This study presents a low-cost and high-efficiency strategy for the fabrication of cellulose aerogel fibers, advancing their potential for thermal insulation applications.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 17","pages":"7393 - 7409"},"PeriodicalIF":3.5,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the generally used nanomaterial dispersion methods commonly affect the physical size and functional group proportion of GO, thus weakening the reinforcing effects of the cement reinforcement. In the present study, the molecular dynamical (MD) simulation was employed to investigate the tensile mechanical properties of calcium silicate hydrate (C–S–H)/GO composites under different physical sizes and oxygen-containing functional group contents of GO nanosheets. The results demonstrate that the mixed GO nanosheet reinforces the C–S–H via ductility and strain energy density reinforcement from the MD perspective rather than a macroscopic peak strength improvement. Benefiting from the crack-bridging roles of GO, the ductility and strain energy density of C–S–H composites can be strengthened by up to 53.6–66.7%. A new \"danger interval\" mechanism is found in GO modification cementitious composites. With an increment of the physical size and oxygen-containing functional group content of inserted GO, the peak stress, ductility, and strain energy density of the GO/C–S–H composites all demonstrate a first declining and then rising trend, hitting the lowest value at 0.18 oxygen–carbon ratio and 0.48 size ratio with C–S–H in the <i>z</i>-axis direction. The tensile strain and stress characteristics further illustrate that inadequate nanosheet size and oxygen-containing functional group content weaken the ability of strain/stress redistribution capability of GO, thus limiting the reinforcement efficiency of the GO.

Composites are often used, but their preparation requires numerous parameters and attempts to maximize the crystalline phase or texture. To limit the number of syntheses, factor analysis is a useful tool for determining the critical parameters. This method has been applied to titania-based anodes. Biomass-derived carbon-titania composites were prepared through sol–gel synthesis followed by drying and pyrolysis under a nitrogen gas flow. Four synthesis parameters were investigated: the presence of kapok-based carbon fiber, the acid used as the sol–gel catalyst, the drying process, and the pyrolysis temperature. Owing to the Yates formula, the optimal conditions leading to an optimized specific surface area (SSA) enhancing lithium-ion diffusion are highlighted. Conclusively, whereas kapok-based carbon and supercritical drying are essential for achieving high SSAs, the effect of pyrolysis temperature on TiO₂ crystallinity depends on the acid-based sol–gel conditions, and to favor anatase instead of rutile, acetic acid should be used. As a result, this method of synthesis and implementation has made it possible to use the most suitable samples without extra conductive carbon as anodes in lithium-ion batteries and their electrochemical characteristics have been obtained using galvanostatic measurements over 40 cycles.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 17","pages":"7259 - 7272"},"PeriodicalIF":3.5,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-025-10874-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
