After the modification
by methyltrichlorosilane (MTCS), the aerogels
acquired superhydrophobicity with contact angles of as
high as 151–155. In addition, their adsorption efficiency
for various common organic solvents and waste oil can
reach up to 53–93 g g-1. For measuring their adsorption
recyclability, we put the aerogels into a thin and lightweight
nonwoven cloth bag considering the poor
mechanical property of the aerogels, and the bag filled with
the samples were dipped into various organic liquids.
