| 摘 要： | 为研究电流变液的剪切强度, 首先采用化学共沉淀法合成棒状草酸氧钛酸钙(CTO)纳米颗粒, 通过改变聚乙二醇的相对分子质量、用量以及水和乙醇的配比调节颗粒形貌; 然后将最优条件下制备的棒状结构CTO纳米颗粒均匀地分散在硅油中, 发现制得的电流变液表现出优异的电流变特性和抗沉降性, 屈服应力可达180 kPa.

| Abstract: | To study the shear strength of electrorheological fluid, we synthesize the calcium titanyl oxalate (CTO) nanoparticles by using chemical co-precipitation method. The morphology of the particles is controlled through changing the molecular weight and the amount of PEG, the ratio of ethanol and water. Then, the rod-like CTO nanoparticles prepared with the optimal conditions are dispersed in the silicone oil, with which the electrorheological fluid exhibits excellent electrorheological and anti-settling properties. The yield stress can reach as high as 180 kPa. |
