采用阴极等离子体电解法，利用等离子体的巨大能量，通过控制溶液中Ti（SO 4）2的浓度，一步法制备出花生状的二氧化钛微粒。对微粒的形貌和结构进行了表征，在其表面获得了约3-10 nm的微小纳米结构，显著提高了其表面粗糙度和比表面积。这些表面具有纳米结构的花生状TiO 2颗粒被认为是由两个熔融的TiO 2颗粒碰撞然后在Ti（SO 4）2溶液中急剧冷却形成的。最重要的是，使用旋转流变仪的花生状二氧化钛微粒的电流变（ER）行为进行了表征。与传统的TiO 2粉体相比，花生状纳米颗粒具有更好的电流变效应，这是由于其独特的形状和表面纳米结构。
Peanut shaped TiO2 micro-particles were prepared by using the huge energy of the plasma and controlling the Ti(SO4)2 concentrations in aqueous solutions via a one-step method, cathode plasma electrolysis. The morphology and structure of the micro-particles were characterized, and the tiny nanostructures about 3–10 nm were obtained on their surface, which obviously increased their surface roughness and specific surface area. These peanut shaped TiO2 particles with nanostructures on their surface were considered to be formed by the collision of two molten TiO2 particles and then the sharply cooling in Ti(SO4)2 solution. Most of all, the electrorheological (ER) behaviors of the peanut shaped TiO2 micro-particles were characterized using a rotational rheometer. Compared with the traditional TiO2 powders, the better ER effect of the peanut shaped micro-particles was attributed to their unique shape and special surface nanostructures.
