Surface modification method of fine magnetite particles by use of silane coupling agents having fluorocarbon chain was investigated. The magnetic fluid (1, 1, 2-trichloro-1, 2, 2trifluoroethane base) was prepared preliminarily by using oleic acid as a surfactant, and then allowed to react with the silane coupling agent. The amount of oleic acid removed from the magnetite surface during the reaction with the coupling agent was measured by the alkaline titration in methanol, and the high exchange rate (>99%) was observed. The modified fine magnetite particles with silane coupling agent could be well dispersed in poly (chlorotrifluoroethene) and produced the fluoro-oil based magnetic fluid.
