Super-hydrophobic filter papers were prepared by using SiO₂ nano-particles midified by silylating reagent.The water contact angle on the filter papers was higher than 150°.Thermogravimetry and scanning electron microscope were used to characterize the filter paper.The results showed that SiO₂ nano-particle layer was formed on the micro-fibers of filter paper.The combined nano-and micro-structure produced the super-hydrophobic property of the filter paper.The oil-water separation ability of the paper was also investigated,high oil-water separation efficiencies of the paper,especially for high-viscosity mixtures,were confirmed.
