摘　　要：探讨了 Ｆｅ（ＣＯ）５热分解条件和表面活性剂对制备金属磁性液体的影响。结果表明，在Ｆｅ（ＣＯ）５热分解温度为１８０～２２５℃、Ｆｅ（ＣＯ）５蒸发温度为 ３０～５０℃、稀释比为 ３０： １～５０：１的条件下，采用亚胺或复合型表面活性可以制备性能较好的金属磁性液体。The Influences of Fe(CO)5 thermal decomposition condition and surfactant on the preparation of metal magnetic fluid were discussed in this paper. The result shows that metal magnetic fluid can be synthesized by using imine or composite surfactant with appropriate conditions that the Fe(CO) 5 thermal decomposition temperature is from 180 to 225℃, the Fe(CO)5 evaporation temperature is from 30 to 50℃ and the dilution ratio is from 30: 1 to 50: 1.
