Abstract

Superhydrophobic SiO2 aerogel was prepared by sol-gel method using water glass as silicon source.The superhydrophobic SiO2 aerogel gel was uniformly mixed with polydimethylsiloxane（PDMS），sucrose and glucose were introduced as templates to prepare superhydrophobic SiO2/PDMS sponge.The microstructure and composition were characterized by scanning electron microscopy（SEM），X-ray diffraction（XRD），Fourier transform infrared spectroscopy（FT-IR），etc.Its wetting performance was characterized by contact angle measuring instrument.With oil-water mixture as model pollutant，the effects of SiO2 aerogel content and sugar proportion on adsorption properties of sponge were studied.The results showed that the SiO2/PDMS sponge had superhydrophobic and lipophilic properties，with a water contact angle（WCA） of 152.1°.It revealed good removal effect in simulated oil-water adsorption experiments，with removal rate of 98% and 95% for vegetable oil and pump oil，respectively.After oil-water separation experiments repeated for 20 times，adsorption capacity and contact angle of SiO2 /PDMS sponge did not change significantly，and still showed good hydrophobic performance.
