Summary:The invention relates to a solid-liquid interface self-assembly preparation method for a graphene oxide film, which comprises the following steps: adding graphite oxide into solvent to carry out ultrasound with the ultrasonic power of 20-300W; after aluminum or aluminum alloy is carried out natural oxidation layer removal preprocessing, placing the aluminum or the aluminum alloy into acid electrolyte; applying voltage to carry out first anodic oxidation processing; soaking in a mixing solution of phosphoric acid and chromic acid to remove a first anodic oxidation film so as to retain a highlysequential shell-shaped convex-concave structure on the surface of the metal aluminum; carrying out second anodic oxidation under the same condition with the first anodic oxidation; adopting a concaveposition as an initial forming locus of a hole and forming a highly sequential hole array so as to acquire a porous anodic aluminum oxide solid film attached to a matrix of the aluminum; soaking theanodic aluminum oxide film
