Abstract	Authors present a facile method for preparing magnetically driven durable superhydrophobic polyester materials by simply dip-coating in a nanocomposite solution. They prepared a nanocomposite via the polymerization of tetraethoxysilane and n-hexadecyltriethoxysilane in the presence of the Fe3O4 nanoparticles. The coated magnetic samples show superior superhydrophobicity, superoleophilicity, and mechanical and chemical stability, thanks to the tight binding of the nanocomposite on the polyester materials and the inherent stability of the polymerized organosilanes. The superhydrophobic materials can quickly absorb gasoline, diesel and crude oil, and show very high selectivity in oil/water separation.
