Abstract

The invention relates to a method for electrochemically preparing sea-urchin-shaped ZnO nanowire arrays on an organic flexible material. The method comprises the following steps: firstly, adopting a self-assembly method to deposit orderly monolayer polystyrene microspheres on the organic flexible material, then electrochemically depositing good ordered ZnO nanowires on the surfaces of the microspheres, and therefore obtaining radial sea-urchin-shaped ZnO nanowire arrays. The preparation method of the sea-urchin-shaped ZnO nanowire arrays has the advantages of cheap needed materials, friendly environment, simple equipment and steps, short preparation cycle and easiness in synthesis. The prepared ZnO nanowires are composed of ZnO nanocrystallines, the height and the diameter can be regulated and controlled, and the prepared ZnO nanowires have good optical and electrical properties and can be widely applied to the fields of nanocrystalline solar cells, nano sensors and the like.
