This invention discloses a superhydrophobic fiber membrane with a wrinkled structure and its preparation method. The preparation method is as follows: immersing a polypropylene fiber membrane in a methanol solution of a photoinitiator; removing it and irradiating it under a UV lamp; then immersing it in a methanol solution of an amino monomer and irradiating it under a UV lamp; then immersing it in a hexane solution of an acyl chloride, removing it, and then immersing it in a methanol solution of a hydroxyl monomer for interfacial polymerization; removing it; drying it; immersing it in a hexane solution of a long-chain alkylchlorosilane, removing it, and drying it to obtain a superhydrophobic fiber membrane with a wrinkled surface structure. The method of this invention is simple, easy to implement, and operates under mild conditions, requiring no precision instruments. It offers fast separation speed, high efficiency, and good reusability. When used to separate water-in-oil emulsions containing surfactants, the wrinkled structure on the fiber membrane surface increases the contact area between the superhydrophobic surface and the emulsion, promoting the coalescence and demulsification of microemulsions, and achieving a water retention rate of over 99%.
