Developing multifunctional separation membranes, especially composite membranes that are corrosion-resistant, fouling-resistant, and easy to collect, has become a new challenge treating oily wastewater in complex environments. Therefore, superhydrophobic magnetic composed of polystyrene/poly(acrylonitrile)-poly(vinylidene fluoride)/poly(dimethylsiloxane)- iron oxide/titanium dioxide nanoparticles (PS/PAN-PVDF/PDMS@Fe3O4/TiO2), which possess exceptional corrosion resistance UV absorption properties, were fabricated through the process electrospinning. Controlling doping ratio Fe3O4/TiO2, with excellent superhydrophobicity (156.9°), mechanical properties (3.67 MPa 75.93%), thermal stability (330°C) obtained. The membrane demonstrates outstanding (WCA>150°) even after being immersed various corrosive solutions for 120 hours. Under visible-ultraviolet irradiation, exhibits significant red-shift phenomenon, providing certain degree fouling. In presence field, maximum saturation magnetization 9.98 emu/g, field drive can attract. oil adsorption capacity was 29-112 g/g, also maintained 88% initial value ten cycles. addition, comprehensive evaluation conducted assess membrane's flux, efficiency, cycle life when exposed acidic alkaline solutions. results indicated 40 cycles, oil-water flux efficiency remained at 6971 L.h-1.m-2 97%, respectively, representing 24.2% increase compared unmodified membrane. promising potential harsh
