The application belongs to the technical field of poly-methyl-acrylimide foam preparation, and particularly relates to super-hydrophilic and super-oleophilic poly-methyl-acrylimide foam and a preparation method thereof. The poly-methyl-acrylimide foam is prepared by using polyvinyl alcohol and metal oxide powder as raw materials, and the poly-methyl-acrylimide foam is soaked in a weak acid solution, so that the polyvinyl alcohol on the surface of the filler is dissolved, and a surface etching reaction between the weak acid solution and the metal oxide powder is utilized to construct a micro-nano rough structure on the surface of the poly-methyl-acrylimide foam, so that the poly-methyl-acrylimide foam has good affinity with polar and non-polar polymers, and the super-hydrophilic and super-oleophilic characteristics are realized. The problems of insufficient impregnation of the poly-methyl-acrylimide foam surface and resin, and insufficient bonding strength between the adhesive and the foam interface are overcome.
