Method for preparing structural color pattern, structural color pattern prepared by method and application

The invention provides a method for preparing a structural color pattern, the structural color pattern prepared by the method and application, and relates to the technical field of structural colors.The method comprises the following steps of firstly forming a porous alumina film on the surface of aluminum, then covering the porous alumina film with a mask, and forming the structural color pattern on the surface of the porous alumina film by adopting a photoetching method. The structural color pattern prepared by the preparation method is bright in color and clear in picture composition boundary, and the prepared structural color is a physical color and has the advantage of being environmentally friendly compared with patterns prepared from existing pigments and pigments and the like. 本发明提供了一种制备结构色图案的方法及其制得的结构色图案和应用，涉及结构色技术领域，该方法首先在铝表面形成多孔氧化铝薄膜，随后将掩膜板覆盖于多孔氧化铝薄膜上，采用仿光刻法在多孔氧化铝薄膜表面形成结构色图案。由上述制备方法制得的结构色图案颜色鲜艳、构图边界清晰，而且制得的结构色为物理色，相对于现有的颜料和色素等制得的图案具有对环境友好的优势。
