Abstract

The invention provides a preparation method of a uniform-color-generation low-angle-dependence structure color development material, and belongs to the technical field of preparation of structure color development materials. The problem of color distribution uniformity caused by non-uniform particle deposition in the process of forming the structural color developing material by colloidal particles and the problem of angle dependence of the presented structural color at different visual angles are solved. According to the method, the surface of a modified silicon dioxide special structure is coated with a specific substance, composite particles with irregular-shape protruding structures distributed randomly and discretely are prepared, and then the composite particles are combined with a transparent medium to form the structure color developing material with uniform color generation and low angle dependence. The structural color developing material prepared by the method has the characteristics of uniform color distribution, good color developing effect and low angle dependence, and can be applied to the fields of decoration, display, pigments, 3D printing coloring, printing, anti-counterfeit labels and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of structural chromogenic materials, and in particular relates to a preparation method of structural chromogenic materials with uniform color and low angle dependence. Background technique [0002] Structural color is a special color phenomenon produced by interference and diffraction between micro-nano-scale physical structures and light. Its unique structural color rendering characteristics and special structural color effects make it widely used in printing, textile, color reproduction and other fields. application value. According to the visual characteristics of the human eye, structural colors are usually divided into iridescent colors and non-iridescent colors. The structural color of iridescent color is angle-dependent, and it will change significantly with the change of viewing angle, which limits its application in the field of wide viewing angle; non-iridescent structural color has...
