Hydrophobic and oleophilic absorbents have been widely studied for oil spill cleanup but often suffer from low biocompatibility and poor reusability. In this study, ultralight, flexible, and hydrophobically modified TEMPO-oxidized cellulose nanofibril (CNF)-based aerogels were fabricated using chemical cross-linking of CNF, PVA, glutaraldehyde, and sodium alginate (SA), followed by freeze-drying and methyltrichlorosilane (MTCS) vapor-phase silanization. The resulting aerogels exhibited interconnected porous structures with tunable pore size depending on CNF content. The 0.5CNF/SA/PVA aerogels achieved a high water contact angle of 139.5° and demonstrated outstanding oil adsorption capacity (e.g., 40.25 g/g for sunflower oil). Adsorption behavior followed the pseudo-second-order kinetic model more closely than the first-order model. Additionally, cytotoxicity testing revealed high biocompatibility, with less cell damage than the positive control. These findings suggest that hydrophobic CNF-based aerogels are promising candidates for environmentally friendly oil spill remediation and oily wastewater treatment. © 2025
