The application of superhydrophobic materials in the separation of oil/water mixtures has been widely concerned, because of its unique interface properties. The research was prepared magnetic driving superhydrophobic sponge, which adopts the dipping method with Fe3O4 nanoparticles and stearic acid to modify the surface of polyurethane sponge. The magnetic driving superhydrophobic sponge was characterized by XRD, FTIR, TG, etc. The water contact angle up to 158˚ and the thermal stability of sponge is significantly improved; its elastic performance is not damaged. Moreover, the water contact angle is still higher than 148 ˚of the as-prepared sponge under severe conditions such as high temperature (50~90℃ hot water and air) and strong corrosion (pH=2~13), etc. The as-prepared sponge exhibited excellent separation capacities for oil/water mixtures, and it can be driven and recycled oil simply by magnets.
