为了提高电流变效应，采用改进的溶胶-凝胶法制备了一种新型复合材料-尿素掺杂的TiO 2颗粒（TU）。采用扫描电子显微镜（SEM）、X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）和X射线光电子能谱（XPS）对TU粒子的结构和形貌进行了观察和分析。研究了TU粒子的介电性能和基于TU粒子的电流变效应。考察了粒子与硅油之间的润湿性对电流变性能的影响。
Aimed at the increasement of ER effects, a novel composite, urea doped-TiO2particles (TU) were prepared by using a modified sol–gel method. The structure and morphology of the TU particles were observed and analyzed by scanning electron micrpscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectrometry(FT-IR) and X-ray photoelectron spectrum (XPS). The dielectric properties of the TU particles and the ER effects based on the TU particles were investigated. The influence of wettability on the ER performance between the particles and silicone oil was examined.
