【Abstract】 In this paper, a non-water based magnetic fluid—ethylene glycol-based magnetic fluid has been developed.The preparation of glycol-based magnetic fluids has not been reported, which is a good foundation for expanding the experimental research of non-water-based magnetic fluid, at the same time, it is the first time to apply it to the preparation and research of magnetic deformation membrane materials.In this experiment, the magnetic nanometer Fe₃O₄,ethylene glycol-based magnetic fluid and flexible magnetic composite membrane were characterized by XRD,VSM,SEM,IR,electronic universal material testing system and other testing methods.The experimental results showed that the prepared nano-Fe₃O₄ has good magnetic induction intensity, ethylene glycol-based magnetic fluid has good magnetism and stability and the glycol-based magnetic fluid/PVA composite membrane not only maintains the good magnetic properties of the flexible magnetic composite membrane, but also shows the good flexibility of the magnetic composite membrane.The flexible magnetic composite film has the characteristics of smooth surface and good mechanical properties.更多还原
