Superhydrophobic silica wool—a facile route to separating oil and hydrophobic solvents from water

Silica microfiber wool was systematically functionalized in order to provide an extremely water repellent and oleophilic material. This was carried out using a two-step functionalization that was shown to be a highly effective method for generating an intense water repulsion and attraction for oil....
