Abstract

The invention relates to a self-cleaning stainless steel plate and a production method of the self-cleaning stainless steel plate. The self-cleaning stainless steel plate comprises a stainless steel matrix. The surface of the stainless steel matrix is provided with copper plating. The copper plating is provided with multiple structure units arranged regularly. Each structure unit comprises a three-level graded structure and multiple submicron-grade protrusion structures distributed on the bottom surface of the copper plating. The surface of each submicron-grade protrusion structure is provided with multiple nano-scale grain structures which are accumulated in a layered shape. According to the self-cleaning stainless steel plate and the production method of the self-cleaning stainless steel plate, a one-step brushing electroplating technology is adopted, a traditional organic coating is replaced in the electroplated layer, the self-cleaning stainless steel plate without any surface chemical modification is formed, so that the application range of the metal material is further expanded, and the self-cleaning stainless steel plate can be applied to corrosion prevention, micro-flow systems, oil-water separation and the like.
