摘要：In this work, we used cellulose nanofibers (CNF) as the skeleton, Fe3O4@ZnO composite particles as magnetic synergist particles, 3-(2-aminoethylamino) propyltrimethoxysilane (AS) and trimethoxy(octyl)silane (OTMS) as water-based hydrophobic modifiers to prepare magnetic and superhydrophobic cellulose nanofibers based-aerogel with low density and intricate three-dimensional structure. Fe3O4@ZnO confers magnetic properties (3.82 emu/g) and exceptional thermal stability (water contact angle of 150.1(degrees) at 200 C-degrees) to the system, while the combination with OTMS/AS endows the system superhydrophobic (157.5(degrees)) and excellent mechanical properties (stress of 96.95 kPa at 80% strain). It is worth noting that in the process of modifying the system with OTMS/AS, no organic solvents and acidic substances are used in the solution. Benefiting from their synergies, the system demonstrates a notable oil absorption capacity (12.31-41.91 g/g) and outstanding oil selectivity (exceeding 90%), driven by gravity alone. Interestingly, this system, marked by its cost-effectiveness, simplicity, eco-friendliness, and heightened efficiency, holds promising prospects for diverse applications in different oil-water separation behavior and purifying industrial oil wastewater, as well as oil flooding incidents.
