Abstract
Magnetorheological fluids (MRFs) are smart materials made by base fluid, magnetizable particles, and stabilizer additives. A series of samples on varying of silicone oil, carbonyl iron particles, and oleic acid were prepared to investigate the stability of sedimentation and electrical conductivity property. Experimental results showed that the sample with mole ratio of oleic acid and carbonyl iron particles is two has the smallest saturation resistance, fastest response to external field, and the best stability of sedimentation. Further investigations suggested that low silicone oil viscosity and suitable amount carbonyl iron particles were desirable for enhance the electrical conductivity property of MRFs.
