Abstract
The application belongs to the field of optics and nanomaterial self-assembly, and provides a material with structural color and a preparation method and application thereof. A polymer nanoring is used as an assembly unit, an easily volatile organic solvent is used as a dispersion medium, and a water vapor interface is used as an assembly interface. A self-assembly process induced by an interface surface tension gradient is used to make the nanoring array directionally arrange on the water surface. The nanoring has an outer diameter of 500-1000 nm and a thickness of 100-400 nm. Subsequently, LB film analyzer technology is used to controllably transfer the closely arranged nanoring array to a transparent substrate under suitable film forming pressure, film forming speed, film pulling speed and film pulling pressure to obtain a material with structural color. The structural color material prepared by the application has obvious structural color and angle correlation, and the structural color can be regulated by the size of the assembly unit, and is suitable for use in the fields of display, anti-counterfeiting, encryption and the like.
