Preparation method of polystyrene microsphere template and method for preparing zinc oxide thin film

The invention belongs to the field of new energy of photoelectric materials, relates to a preparation method of a polystyrene microsphere template and simultaneously relates to a method for preparing an ordered porous zinc oxide thin film by utilizing the preparation method of the polystyrene microsphere template. The method comprises the following steps: firstly preparing polystyrene microsphere suspension, using the polystyrene microsphere suspension to moisten one surface of a substrate A, then placing the substrate A with the upward moistened surface underwater, leading polystyrene microspheres on the substrate A to diffuse on the water surface, being spontaneously assembled into a single-layer polystyrene microsphere thin film under the action of water surface tension, then transferring the single-layer polystyrene microsphere thin film onto a substrate B, and airing the substrate B for forming the polystyrene microsphere template. The method produces the polystyrene microsphere template by utilizing the self-assembly nature of the polystyrene microspheres under the action of the water surface tension, the preparation method is simple, time-saving and material-saving, and the prepared polystyrene microsphere template has the advantages of large area, ordered property and single layer, thereby providing the prior prerequisite for preparing materials with large-area porous ordered structures.
