The invention discloses a method for manufacturing a petal-imitating super-hydrophobic high-adhesion surface. The method includes the following steps that firstly, a hydrogen bubble template method is used for electroplating a layer of porous metal film on the surface of a metal sheet; secondly, the manufactured porous metal film is placed in an electric heating furnace to be oxidized, and a porous metal oxide template is obtained; thirdly, a high polymer curing system is mixed according to a proportion, normal hexane is added into the high polymer curing system, the mixture is poured into the porous metal oxide template, vacuum pumping is performed, curing is performed, the template is removed with a mechanical separation method after curing, and the petal-imitating super-hydrophobic high-adhesion surface is obtained. The method is simple, convenient to carry out, friendly to the environment, free of large instruments, low in cost and capable of being used for manufacturing petal-imitating micro-morphology surfaces, and experiment parameters are controllable. A micro-protrusion structure has the super-hydrophobic performance, the high-adhesion capacity, the self-cleaning capacity, the good mechanical stability, the strong acid-base corrosion resisting capacity and the good application prospect, and industrialization is hopefully achieved.
