Method for preparing nano-titanium oxide/amide derivative electrorheological fluid

The invention relates to a method for preparing current liquid-change material, especially relating to a titanium oxide/acidamide derivative nanometer current liquid-change material. Compared with former relative method, the inventive current liquid-change material uses glacial acetic acid to restrain the hydrolyzation of butyl titanate, and prevents the reunite of nanometer particles via adjusting the pH value of solution and adding surface activator, The invention has easy operation and lower cost, which the prepared diffused phased material is core-shell nanometer particles that the nanometer titanium oxide particles is basic core, and the acidamide derivative with high dielectric constant is the coating layer. Said structure can improve the dielectric property and conducting property of material to make the current liquid-change have some excellent properties: strong current change effect, better anti-deposition stability, lower electricity density, and better chemical stability.
