Method and device for preparing functional film with cross-scale micro-nano structure through laser enhanced electrochemical deposition

The invention discloses a method and device for preparing a functional film with a cross-scale micro-nano structure through laser enhanced electrochemical deposition, and belongs to the field of laser composite electrochemical preparation. According to the method, the thermal effect and the photoelectric effect of laser irradiation are utilized, the rate and the quality of electrodeposition in an irradiation area are enhanced, a cross-scale micro-nano structure is selectively induced while a plating layer is deposited, and the precision and the uniformity of the micro-nano structure can be improved while the functional surface preparation process is simplified. And a laser enhanced electrochemical deposition method is adopted, so that substrate damage caused by etching is avoided. Compared with the prior art, the functional film prepared by the invention can be taken down from the substrate and adhered to the working surface, so that the working performance, the stability and the service life are improved and
