抄録	We propose a two step modification of iron nanoparticles, including is pre-oxidation to grow the thin oxide layer with nanoscale roughness and subsequent fatty acid capping, for preparing colloidal magnetorheological (MR) fluids. The solid loading of the iron nanoparticles was 15 vol%, and a fatty acid of oleic acid was used as surfactant. We demonstrate the prepared MR fluid displays a good redispersibility and significant field-dependence yield stress when we add the adequate amount of oleic acid to the fluid. Additionally, dynamic measurements were performed to investigate field-induced aggregation structures.
