Abstract: PURPOSE: Provided is an anhydride-based electrorheological fluid containing chitosan dicarboxylate, which is excellent in electrorheological property, dispersion-stability, corrosion-resistance, abrasion-resistance, friendly property to environment, and high temperature stability. CONSTITUTION: The anhydride-based electrorheological fluid is produced by a process comprising the steps of: reacting chitosan and dicarboxylic acid in the presence of a catalyst in dimethyl formamide at an ordinary temperature for 1-24 hours to obtain the chitosan dicarboxylate; mixing 1-50wt% of the chitosan dicarboxylate and 50-99wt% of a base oil at 30-80deg.C, wherein the chitosan dicarboxylate has an average particle diameter of 1-30 micrometer and the base oil is selected from mineral oil, vegetable oil, and synthetic oil.
