Disclosed is a semipermeable membrane and its preparation method. The semipermeable membrane obtained has a Turing structure. The Turing structure is an ordered pattern composed of microstructures. The existence of the structure enables the semipermeable membrane of this invention to have both high water permeation flux and excellent salt retention performance, which breaks the flux limit value of the semipermeable membrane while ensuring high selective permeability of the membrane. It also has good anti-pollution properties. The preparation method of the invention can be easily integrated into the existing semipermeable membrane production line without further cost input which has far-reaching practical significance and commercial value.
