The as-prepared aerogel had a three-dimensional cellular microstructure with ultra-low density of 6.05 mg\u00b7cm\u22123 and high porosity (99.61%). After modifying by chemical vapor deposition (CVD) with hexadecyltrimethoxysilane (HTMS), the nanocellulose aerogel displayed stable super-hydrophobicity and super-oleophilicity with water contact angle of 151\u00b0, and had excellent adsorption performance for various oil and organic solvents with the adsorption capacity of 77~226 g\/g. Even after 30 cycles, the adsorption capacity of the nanocellulose aerogel for chloroform was as high as 170 g\/g, indicating its outstanding reusability. Therefore, the superhydrophobic cross-linked nanocellulose aerogel is a promising oil adsorbent for wastewater treatment.<\/jats:p>","DOI":"10.3390\/polym13040625","type":"journal-article","created":{"date-parts":[[2021,2,19]],"date-time":"2021-02-19T09:06:10Z","timestamp":1613725570000},"page":"625","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":69,"title":["Facile
