Abstract EN
Few cases of hydrophobic materials synthesized in water have been reported.
In this work, water, as the only solvent, is used to prepare a superhydrophobic sponge via a facile and environment-friendly route.
The as-prepared sponge, namely silylated polyvinyl alcohol (PVA) sponge, exhibits superhydrophobic and superoleophilic characters.
It has the static water contact angle (WCA) of 152 ± 1 and the static oil contact angle (OCA) of 0°, which can lead to excellent selectivity for oil-water separation.
Besides, the methyltriethoxysilane (MTES) can form a stable mixed structure with the PVA skeleton, resulting in the rare shedding of polymethylsiloxane nanoparticles and the long-term stability for oil-water separation.
Furthermore, the silylated sponge shows a high separation efficiency (>99.6%), removing oil up to 6200∼14000 times of its own mass.
The findings demonstrated that the silylated superhydrophobic sponge can be a promising candidate in water treatment application.
