Abstract

The invention discloses a high-refractive index microsphere Mie scattering based schemochrome coating. The high-refractive index microsphere Mie scattering based schemochrome coating comprises the following components by mass: 1-4 parts of high-refractive index micron and nano microsphere, 15-20 parts of dispersion liquid, 0.1-3 parts of surfactant, and 1-6 parts of adhesive. The color of the schemochrome coating is from a single-layer or multi-layer local microcosmic ordered and macroscopic long-range unordered structure assembled on a matrix by high-refractive index microspheres with even grain size in the coating, and the color is one of the schemochrome, and is not relevant to the color of the high-refractive index microsphere. Compared with the color produced by other color producingstructures of the schemochrome, the color is visible under the natural light, irradiation by a special light source is not needed, or the specular reflection observation is not needed, and the color is brighter. In addition, by changing the grain size of the added high-refractive index microsphere, the schemochrome coating finally obtains the angular independent schemochrome of multiple colors like purple, blue, green, yellow and red.

Description

technical field [0001] The invention relates to a structural color coating based on high refractive index microsphere Mie scattering, which belongs to the field of structural color. Background technique [0002] In nature, colors come from two sources—pigment-derived and structurally-derived. Compared with pigment chromophore, structural chromophore has the advantages of high brightness, high saturation, and never fades. Structural chromaticity originates from the interaction between visible light and the micro-nano structure of matter, such as scattering, interference or diffraction. At present, in the research of artificial structural color, it is mainly realized by photonic crystal and amorphous photonic structure. It is the most common way to realize structural color construction by photonic crystal structure, which can produce bright structural color (see patent CN200710064245.0; X.Wang, Z.Wang, L.Bai, H.Wang, L.Kang, D.H.Werner, M.Xu, B.Li, J.Li and X.-F.Yu, Opt.Exp...
