Description

technical field [0001] The invention belongs to the technical field of stainless steel surface nanorod arrays. The invention relates to a method for preparing a zinc oxide nanorod array on a stainless steel surface. Background technique [0002] The research and preparation of ZnO as a semiconductor material has a long history. With the development of nanomaterial science, the research on ZnO nanoarrays has set off a new upsurge. ZnO nanomaterials have important applications in the fields of electroluminescence, solar cells, photocatalysis and sensors. However, there are also some problems in the preparation and application of ZnO nanomaterials, which require a preparation process suitable for industrial production and suitable substrate materials to adapt to harsh environments. Stainless steel material has excellent corrosion resistance, wear resistance and toughness, and can adapt to relatively harsh pollution environment. At the same time, it has good processability, st...
