Abstract: The invention relates to a method for preparing an alpha-linolenic acid molecular engram polymer material. The method comprises the following steps of: adding alpha-linolenic acid and beta-cyclodextrin to a container, adding dimethyl sulfoxide, stirring for polymerizing to obtain an alpha-linolenic acid prepolymerization solution; adding hexamethylene diisocyanate or methylbenzene-2,4-diisocyanate and polymerizing to obtain alpha-linolenic acid polymerization grains; and cooling, washing, drying and grinding to obtain the alpha-linolenic acid molecular engram polymer material. According to the method for preparing the alpha-linolenic acid molecular engram polymer material, disclosed by the invention, alpha-linolenic acid is taken as template molecules, beta-cyclodextrin is taken as a functional monomer, contains polyhydroxy groups and more functional hydroxyl groups and has the characteristics of interior hydrophobicity and exterior hydrophilcity, and therefore beta-cyclodextrin can be fully polymerized with the alpha-linolenic acid to form a polymer containing the alpha-linolenic acid in a crosslinking manner; and after elution, the polymer containing the alpha-linolenic acid has engram holes consistent with those of the alpha-linolenic acid, thus the engram polymer material having higher specific selective absorption function to the alpha-linolenic acid is obtained.
