Embodiment 1
[0060] Example 1 Preparation of Co 0.2 mn 0.8 Fe 2 o 4 Polyalphaolefin synthetic oil-based magnetic fluid
[0061] S1. Preparation of nano-D x m 1-x Fe 2 o 4 Magnetic Particles:
[0062] Prepare 100ml Co 2+ , Mn 2+ , Fe 3+ A mixed solution of diethylene glycol (DEG), placed in a beaker, where Co 2+ The concentration is 0.08 mol / L, Mn 2+ The concentration is 0.32 mol / L, Fe 3+The concentration is 0.8 mol / L. Prepare 120 ml of NaOH aqueous solution with a concentration of 3 mol / L and place it in a 500 ml round bottom flask. Use argon as a protective atmosphere, heat up to the boiling of the NaOH solution (110-130°C), stir at a speed of 500r / min, slowly add the DEG solution of metal ions into the NaOH solution for 10 minutes, and continue the reaction for 5 minutes to prepare Nano Co 0.2 mn 0.8 Fe 2 o 4 magnetic particles;
