Abstract
Hydrophobic nanoparticle compositions include silica nanoparticles capped with asphaltene succinimide alkoxy silane (ASAS). The nanoparticles can have a particle size ranging from about 20 nm to about 10000 μm. The nanoparticle compositions can be used as a coating for raw sand to provide a super-hydrophobic sand. The nanoparticle compositions can be used as a coating for a polyurethane (PU) sponge to provide a super-hydrophobic sponge. The super-hydrophobic sand and/or super-hydrophobic sponge can be used to collect crude oil deposited in aquatic environments as a result of petroleum crude oil spills.
