The invention provides a method for preparing a bismuth ferrite film with dielectric property by adopting a liquid-phase self-assembly technology. The method comprises the following steps of: dissolving Bi(NO3)3.5H2O and Fe(NO3)3.9H2O which serve as raw materials into distilled water, and regulating the pH value of the solution by using glacial acetic acid; preparing a film by using citric acid as a complexing agent, using a functionalized self-assembly single-layer film as a template and suspending the template on the surface of the solution in a mode that the functionalized side of the template is downward through reverse adsorption; drying at room temperature, preserving the heat for 10 minutes at the temperature of 300 DEG C to remove organic substances, preserving the heat at the temperature of 550 DEG C and annealing to prepare a crystallized bismuth ferrite functional film, performing ultraviolet irradiation and reverse adsorption, drying and annealing; and repeating the steps till the bismuth ferrite functional film with the dielectric property is prepared. The bismuth ferrite film with the dielectric property is prepared by combining the advantages of liquid-phase self-assembly through multiple times of reverse adsorption and layer-by-layer annealing.
