Amorphous photonic crystal schemochrome material based on black titanium dioxide and silicon dioxide composite and preparation method of amorphous photonic crystal schemochrome material

Abstract

The invention provides an amorphous photonic crystal schemochrome material based on black titanium dioxide and silicon dioxide composite and a preparation method of the amorphous photonic crystal schemochrome material. The material component comprises SiO2 amorphous photonic crystal and black TiO2, and the mass ratio of the black TiO2 and the SiO2 amorphous photonic crystal is 1 to (0.1-1). The preparation method comprises the steps that (1) black TiO2 nanoparticle powder is prepared, and SiO2 amorphous photonic crystal microsphere powder is prepared; (2) the black TiO2 / SiO2 materials are prepared, specifically, the SiO2 amorphous photonic crystal microsphere powder and the black TiO2 nanoparticle powder are dissolved in ethanol, ultrasonic dispersion is conducted after stirring, and theproduct is dried. According to the preparation method, the schemochrome is combined with the photocatalysis function, the limitation of preparing non-angle independent color material by absorbing coherent scattering light with carbon black as the back bottom is broken, and the obtained material has the function of photocatalytic degradation of pollutants at the same time.

Description

technical field [0001] The invention belongs to the technical field of preparation of structural color materials, and relates to an amorphous photonic crystal structural color material based on the composite of black titanium dioxide and silicon dioxide and a preparation method thereof. Background technique [0002] The dazzling colors used in nature to communicate and camouflage are formed through the complex structural design of the interior. In the past, photonic pigments prepared by photonic crystals and amorphous photonic crystal structures can only replace traditional colors in the application process, and cannot solve the ensuing environmental pollution problems. At the same time, the structural color materials based on photonic crystals are bright and have an iridescent effect, and the non-angle-dependent amorphous photonic crystal structural color materials have been widely studied because of their soft colors and meeting human visual needs. [0003] The amorphous ...

AI Technical Summary

Problems solved by technology

Structural pigments without angle dependence can replace traditional chemical pigments in use due to their characteristics of never fading and soft colors, but structural color materials still cannot alleviate environmental pollution problems in the application process

[0004] Structural color has been extensively studied and deeply explored by researchers for its functionalization because of its physical coloring characteristics. It has great potential for the industrial production of non-angle-dependent structural colorants with amorphous photonic crystal structures that are not harsh in actual production conditions. possibility, but the introduction of carbon black substances such as acetylene black, carbon nanotubes, and graphene, which are light in weight and not easy to disperse, can only absorb coherent scattered light, and do not have the function of degrading pollutants by sunlight, and so far, no carbon The introduction of black matter can prepare angle-independent structural color materials with photocatalytic effect, which has not been reported by researchers.
