Magnetic surfactants are a special class of surfactants with magneto-responsive properties. These surfactants possess lower critical micelle concentrations and are more effective in reducing surface tension as compared to conventional surfactants. Such surfactants' ability to manipulate self-assembly in a controlled way by tuning the magnetic field makes them an attractive choice for several applications, including drug delivery, catalysis, separation, oilfield, and water treatment. In this work, we reviewed the properties of magnetic surfactants and possible explanations of magnetic behavior. This article also covers the synthesis methods that can be used to synthesize different types of cationic, anionic, nonionic, and zwitterionic magnetic surfactants. The applications of magnetic surfactants in different fields such as biotechnology, water treatment, catalysis, and oilfield have been discussed in detail.
磁性表面活性剂是一类具有磁响应特性的特殊表面活性剂。与传统表面活性剂相比，这类表面活性剂具有更低的临界胶束浓度，更能有效地降低表面张力。通过调节磁场来控制表面活性剂的自组装能力，这使得它们在包括药物输送、催化、分离、油田和水处理等多个领域都具有吸引力。在这项工作中，我们综述了磁性表面活性剂的性质和可能的磁行为解释。本文还涵盖了可以用来合成不同类型的阳离子、阴离子、非离子和两性离子磁性表面活性剂的合成方法。详细讨论了磁性表面活性剂在生物技术、水处理、催化和油田等不同领域的应用。
