| Abstract:The fabrication of directionally driven oil-water separation materials has great significance for the removal of oil spills and organic pollutants. In this study, an oil-water separation aerogel capable of directionally adsorbing oil was designed using an anisotropic wood aerogel with a layered structure and a top-down fabrication strategy. Specifically, a magnetic wood-based superhydrophobic aerogel (methyltrimethoxysilane (MTMS)/Fe3O4 wood aerogel) was developed through the in situ co-precipitation of Fe3O4 nanoparticles and chemical vapor deposition. Owing to its highly porous structure, lipophilicity, hydrophobicity (water contact angle of 160°), and high compressibility, the MTMS/Fe3O4 wood aerogel exhibits excellent oil-water separation performance and compression cycle stability. Additionally, the Fe3O4 endows the material with excellent magnetic and photothermal conversion capabilities. These excellent properties make MTMS/Fe3O4 wood aerogel a promising recyclable and sustainable oil-water separation material. |
