| 摘 要： | 在水热反应条件下，采用十二烷基苯磺酸钠（SDBS）对纳米Al2O3进行表面改性处理，通过红外光谱（FT-IR）、X射线衍射（XRD）等手段对表面改性的纳米Al2O3进行了表征；探讨了pH值、十二烷基苯磺酸钠（SDBS）用量对表面修饰效果的影响；对改性纳米Al2O3电流变液进行了性能测试．结果表明，采用SDBS对纳米Al2O3进行表面改性处理，要在中性环境下进行；SDBS含量占纳米Al2O3质量的2．0％左右时，可以获得表面修饰效果理想的纳米Al2O3粒子；SDBS的加入影响了纳米Al2O3颗粒的表面性质，使其与甲基硅油的润湿性大大提高，改性纳米Al2O3含量为30％的电流变液在2kV／mm的电场作用下静态剪切应力可达1．04kPa．

| Abstract: | Nano -Al2O3 modified by sodium dodecylbenzene sulfonate （SDBS） was obtained under hydrothermal conditions. The modified nano -Al2O3 has been characterized by Fourier transform -infrared spectroscopy （ FT - IR）, X - ray diffraction （XRD）. The effects of pH value and the content of SDBS on modification were discussed. The ER behaviors of the modified nano -Al2O3 were also investigated by the test device of ER fluid. The experimental results showed that the modified process of nano - Al2O3 by SDBS should be proceed under neutral conditions. The addition of SDBS affects the surface characterization of nano - Al2O3, which improved the wettability between particles and silicone oil. Under an electric field of 2.0kV/mm, the shear stress will reach 1.04kPa, when the mass fraction of nano - Al2O3 is 30%. |
