Abstract: The invention relates to a preparation method of a self-supporting molecularly imprinted polymer film. The preparation method comprises the following steps of: firstly, reacting divalent metal ions with a porous alumina film to obtain a porous alumina-based layered double hydroxide; secondly, carrying out further reaction to obtain an SBC (Sulpho-Benzoyl Cyanoacetic Acid) intercalated porous alumina-based layered double hydroxide; and finally, mixing the SBC intercalated porous alumina-based layered double hydroxide with a polymerizable monomer, a polymerized cross-linking agent, a molecularly imprinted template agent and an organic solvent, dispersing by using ultrasound wave, adding a free base polymerization initiator for polymerizing, washing a product obtained by reacting and then drying to obtain the self-supporting molecularly imprinted polymer film. According to the self-supporting molecularly imprinted polymer film disclosed by the invention, the advantages of high strength, corrosion resistance, high temperature resistance and great specific area of an inorganic material as well as high load information quantity and adjustable performance of an organic polymer material can be fully exerted; the active free base polymerization is assisted in controlling; and the controllable synthesis of an ultrathin nano self-supporting structure of a molecularly imprinted material can be realized by using the controllability of the growth process of an active chain.
