| 摘 要： | 对SiO2纳米粒子进行硅烷化改性，再将其修饰到滤纸上，制备出静态水接触角＞150°的超疏水滤纸，对制备条件进行了优化。 用热重分析及扫描电子显微镜对超疏水滤纸表征后发现，二氧化硅纳米粒子在滤纸纤维表面形成一层包裹层，即纳米级粗糙结构，这种结构对滤纸的疏水性具有关键作用。 对滤纸的油水分离性能进行了研究，发现其对非均相体系和高粘度油水混合物具有很好的分离效果。

| Abstract: | 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. |

| Keywords: | super-hydrophobic filter paper nanoparticles silylation modification oil-water separation |
