摘　　要：以纳米磁性流体在众多领域的应用潜力为出发点,结合相关研究成果,综述纳米磁性流体的最新研究进展。同时以纳米磁性流体的稳定性、磁性能等为考察的重点,对各种制备方法进行评价与展望。化学共沉淀法因其成本低、操作简单,所得纳米磁性流体稳定性好,是未来研究的重点,但需解决制得的纳米磁性颗粒易团聚的问题。氟醚油基纳米磁性流体与其他油基纳米磁性流体相比,耐高温等性能更优,可以用于苛刻环境下的润滑、密封,将成为纳米流体制备的一个重要研究方向。无毒、单分散、稳定的水基纳米磁性流体因在磁共振造影等生物医学领域具有广泛的应用,而具有可观的发展前景。Based on the application potential of magnetic fluids in many fields and related research results,the latest progress of magnetic fluids is reviewed.Meanwhile,the stability and magnetism are the focus of investigation,and the preparation methods are evaluated and prospected.Because of its low cost,simple operation and admirable stability of magnetic fluid,chemical co-precipitation method is the key point of future research,while it is necessary to overcome the problem that the magnetic particles have the tendency to agglomerate.Compared with other oil-based magnetic fluids,fluoroether oil-based magnetic fluids have relatively high-temperature resistance and can be applyied for lubrication and sealing in harsh environments,which will become an important research direction.Non-toxic,monodisperse and stable water-based magnetic fluids have vital applications in biomedical fields such as magnetic resonance imaging(MRI),thereby havig considerable prospects for development.
