description The invention relates to preparation of a high-pressure-resistant composite membrane for efficiently separating an oil-water system. The method comprises the following steps: firstly, preparing an organic semi-interpenetrating network polymer material from a monomer of any organic polymer and a polyvinylidene fluoride (PVDF) base material through blending and crosslinking, and synthesizing the organic semi-interpenetrating network polymer material into a spinning solution as a shell layer; furthermore, any inorganic nanoparticle and PVDF are doped and blended into a spinning solution as a core layer, and two inorganic and organic materials are combined in the same membrane system through a coaxial electrostatic spinning method, so that the high-pressure-resistant organic-inorganic composite membrane is prepared. The high-pressure-resistant composite membrane has long-term, stable and lasting high pressure resistance, further has the potential of efficiently separating an oil-water system, and provides a novel
