Problems solved by technology

However, the current reports on the preparation of organic-inorganic composite one-dimensional photonic crystals show that it is difficult to obtain organic-inorganic composite one-dimensional photonic crystal structural color materials with excellent performance through conventional liquid assembly methods with low equipment costs such as dipping and spin coating. Because the assembly of the organic polymer layer usually uses a p

Abstract

The invention relates to a one-dimensional photonic crystal structure color generation material and a preparation method thereof and belongs to the field of new material preparation, in particular to the field of new color generation material preparation. The one-dimensional photonic crystal structure color generation material is a periodical laminated structure material formed by organic nano particles and inorganic nano particles on a matrix in an alternative stacking mode. The periodical laminated structure material is obtained by alternatively stacking, drying and curing organic polymer microemulsion or reversed-phase microemulsion and inorganic substance nanometer sol. The one-dimensional photonic crystal structure color generation material can solve the problem that polymer permeates into gaps among the inorganic nano particles when only an organic polymer solution takes part in assembling, the stacking thickness of the polymer is controlled well, and a regular layer-by-layer structure is obtained. The one-dimensional photonic crystal structure color generation material prepared through the method is suitable for wide organic and inorganic materials and has good application prospects in the field of coatings, displaying, naked eye detection, anti-faking and the like.

Description

technical field [0001] The invention relates to a one-dimensional photonic crystal structure chromogenic material and a preparation method thereof, belonging to the field of new material preparation, specifically to the field of chromogenic new material preparation. Background technique [0002] Structural color is a variety of colors formed by light refraction, diffuse reflection, diffraction or interference in a periodic dielectric structure. Compared with pigmented colors, structural colors have the advantages of high brightness, high saturation, and not easy to fade. The main source of structural color is a photonic crystal, which is a photonic bandgap material, that is, a periodic dielectric structure with a photonic bandgap. One-dimensional (1D) photonic crystals have a photonic frequency band gap in one direction, and are formed by alternately stacking two different refractive index media. When the one-dimensional photonic crystal reflects light with a wavelength of ...
