Problems solved by technology

At present, the chromogenic system of artificial photonic crystal structure is mainly obtained by assembling high-refractive-index materials and low-refractive-index materials on the substrate through gravity or capillary action, but the assembly time is as long as several days or even weeks; in order to further improve its assembly and For color performance, on the one hand, related scholars introduce an electric field or magnetic field whose direction and intensity are easy to control into the assembly system, and use the electric field to accelerate the sedimentation of the charged micro-nano structure to the substrate, while the magnetic field accelerates the alignment of the micro-nano structure on the substrate. The electromagnetic field assembly device is more complicated
The artificial photonic crystal structure produces color because its color-producing mechanism is the selective reflection of visible light, and its color is easily interfered by other remaining visible transmitted light and background light, resulting in dim, impure color and difficult assembly

Description

technical field [0001] The invention relates to a chromogenic material with a photonic crystal structure and a preparation method thereof, belonging to the field of new material preparation, in particular to the field of chromogenic new material preparation. Background technique [0002] Structural chromaticity is the reflection, interference or diffraction of light caused by the structural characteristics of objects, thus producing structural color (Pete Vukusic and J.Roy Sambles, Nature, 2003, 424, 852-855) is a new direction of color chemistry today. Structural color generation is mainly realized by technologies such as dielectric layer stacking, etching lithography and colloidal assembly (ZhaoH.Fang, Christian Punckt, Eva Y.Leung, Hannes C.Schniepp and Ilhan A.Aksay. 6696; Shao-Hui Kang, Tzu-Yao Tai and Te-Hua Fang. Current Applied Physics, 2010, 10, 625-630; Velev, O.D., Lenhoff, A.M. and Kaler, E.W. Science, 2000, 287, 2240-2243). Among them, the colloidal assembly is...
