Problems solved by technology

However, incoherent scattering greatly reduces the brightness and contrast of photonic crystal materials, limiting their application in color additives
[0003] The raw materials used in common color additives are usually artificially synthesized, which have the disadvantages of poor dispersion, high price, and harmful to human body; in addition, the raw materials used in synthetic color additives often cause incoherent scattering, which limits the brightness and brightness of colors. Contrast reduces the effect of color additives; and the synthesis process of such color additives is single, and it is impossible to customize a wide variety of color additives according to customer needs

Abstract

The invention provides a preparation method of a smearing type color additive based on composite assembled particles, and the preparation method comprises the following specific steps: S1, preparing a dark pollen substrate: taking original pollen, putting the original pollen into a muffle furnace, and calcining to carbonize the original pollen, so as to prepare the dark pollen substrate; s2, preparing a smearing type color additive: immersing the dark pollen substrate prepared in the step S1 into an alcohol dispersion solution of nano particles for reaction, depositing the nano particles on the surface of the dark pollen substrate to form composite assembled particles, and preparing the smearing type color additive after alcohol is completely volatilized; and S3, preparing the composite smearing type color additive: immersing the smearing type color additive prepared in the step S2 into an alcohol dispersion solution of nanoparticles to react for a plurality of times, so as to prepare the composite smearing type color additive.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a smear-type color additive based on composite assembled particles and a preparation method thereof. Background technique [0002] In recent years, structural colors have attracted extensive attention in different research fields. Structural color is different from pigment color. It is an optical effect caused by the submicroscopic structure of organisms. It is common in some beetle shells, butterfly wings, etc. Structural color has the characteristics of high color reflectivity, high saturation, not easy to fade, and environmental protection. Therefore, researchers have carried out a lot of research on structural colors, and developed artificial structural color materials, among which photonic crystal materials have been widely studied. The photonic crystal material is obtained by self-assembly of nanoparticles, the preparation method is simple, and it also has rich and br...
