Fabrication of superhydrophobic and superoleophilic textiles for oil-water separation

- Hydrophobic SiO2 sol with trimethylsilyl groups was prepared using tetraethoxysilane and 1,1,1,3,3,3-hexamethyl disilazane.
- PET textiles were coated with the as-prepared hydrophobic SiO2 sol.
- Superhydrophobic and superoleophilic textiles were obtained for oil-water separation.
