| Abstract: | A new preparation method was introduced of using both oleic acid and non-ionic surfactants to modify the surface of the nano-sized particles in order to disperse them into the polyether(aqueous).Through the study on the chemical structure of the surfactant,the chemical mechanism of the two-double modification method was discussed.The effects of different structures,quantities,and the modifying temperatures of the non-ionic surfactants on the dispersed phase of the magnetic-fluid were studied.The optimal technics and effect factors were raised accordingly.The new preparation technics can intensively improve the stability of the polyether-based magnetic fluid. |

| Keywords: | non-ionic surfactant polyether-based magnetic fluid disperse |
