摘要： 无机电泳颗粒由于密度相对较大，在分散介质中容易出现沉降，不能很好地分散于介质中。以单层核-壳聚合物粒子为模板，表面沉积钛酸四丁酯，通过湿化学法制备中空的黑色一氧化钛超微/纳米粒子。考察了二氧化硅、三氧化二铝和十二烷基苯磺酸钠（SDBS）对一氧化钛的包覆改性，并用红外光谱、X射线衍射、扫描电镜和透射电镜进行了表征，通过微电泳仪测定粒子的电泳淌度和Zeta电位。研究表明，中空结构能降低粒子的密度，改性后的粒子分散性和Zeta电位有明显的变化。使用三氧化二铝改性时，其电泳性能得到了很大的提高，Zeta电位绝对值高达40.70 mV，具有很好的电泳性能。 

Abstract: Because the density is relatively large,the inorganic electrophoretic particles are easy to deposit and can not be preferably dispersed in media.With monolayer core shell polymer particles as template,hollow black titanium  oxide (TiO) ultramicron/nano particles were prepared via  wet chemistry preparation by depositing tetrabutyl titanate on the surface of template.Coating modifications to TiO were carried out by SiO2,Al2O3,and sodium dodecyl benzene sulfonate (SDBS) and the products were characterized by FT-IR,XRD,SEM,and TEM.Electrophoretic mobility and Zeta potentials were determined by micro electrophoresis apparatus.Results showed that hollow framework could reduce the density of particles,and the dispersion and Zeta potential of particles had distinct change after modification.When TiO particles were modified by Al2O3,the electrophoretic properties were improved apparently.TiO particles modified by Al2O3 had good electrophoretic properties,and the Zeta potential was up to 40.70 mV.
