摘要
An oil-water separation glass-fiber membrane was prepared by a simple sol-gel process using triethoxymethylsilane (MTES) as a precursor. Methyl groups were grafted and hydrophobic nano-pillars were formed onto the surface of glass-fiber in a sol-gel process, thus producing a glass-fiber membrane with super-hydrophobicity and super-oleophilicity. The micro-morphology and surface chemical composition of the glass-fiber membrane were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy, respectively. The wetting behavior of the treated membrane was examined by a water/oil contact angle method. The oil-water separation efficiency was determined by the Cou-Lo Aquamax. The results show that the pore size of the glass-fiber membrane is similar before and after MTES treatment, while hydrophobic -CH3 groups and nano-pillar particles are formed on the surface of treated glass-fiber. The treated glass-fiber membrane exhibits super-hydrophobicity and super-oleophiliciy, and its emulsified water removal efficiency is 96.09%. © 2018, Editorial Department of Journal of the Chinese Ceramic Society.
