Method for loading hydroxyl iron oxide nanoparticle composite structural colors on carbon fiber woven fabrics and carbon fiber woven fabrics obtained according to method

Abstract

The invention discloses a method for loading hydroxyl iron oxide nanoparticle composite structural colors on carbon fiber woven fabrics and the carbon fiber woven fabrics obtained according to the method. The method includes steps: step one, ultrasonically dispersing ferric trichloride powder into deionized water, stirring at the room temperature until solution turns from colorless to orange, adding ammonium fluoride powder into the solution, stirring to obtain transparent clear solution, and transferring the mixed solution into a reactor; step two, cutting the carbon fiber woven fabrics washed with acetone and ethanol mixed solution into a certain size, and soaking in the reactor; step three, performing hydrothermal reaction in a high-temperature drying oven to enable loading of hydroxyliron oxide nanoparticles on the surfaces of the carbon fiber woven fabrics by different densities and thicknesses to finally obtain the carbon fiber woven fabrics in different structural colors. Therefore, the technical problem of deposition of the structural colors on the surfaces of the carbon fiber woven fabrics is solved. The preparation method is simple, feasible and high in repeatability, adopted raw materials are environmentally friendly, safe and nontoxic, and easiness in implementation of industrialization is achieved.

Description

Technical field [0001] The invention belongs to the field of nano composite material preparation, and in particular relates to a method for a carbon fiber woven cloth loaded with iron oxyhydroxide nano-particle composite structure color and the obtained carbon fiber woven cloth. Background technique [0002] The rich color world gives people a beautiful visual experience. Chemical colors and structural colors (also known as physical colors) are two major types of colors. Chemical color refers to the production of color through pigmentation. Although these chemical substances are colorful and simple in color, they are easy to cause waste of resources and environmental pollution. The structural color is the color presented by the grating diffraction, interference and refraction between the special structure of the object itself and the white light. Structural color is not pigmentation, but a kind of physical coloring. It has the advantages of stable color, never fade, environment...

AI Technical Summary

Problems solved by technology

Atomic layer deposition can only coat one film at a time, with extremely uniform thickness and excellent conformality, but on the other hand, this method has a low deposition rate, time-consuming and labor-intensive, and high deposition costs

The Chinese invention patent with application number 201510604482.6 discloses a purple photonic crystal structural color film and its preparation method. The method adopts a uniform deposition method to prepare zinc sulfide microspheres, and then adopts a vertical deposition method to self-assemble into a purple photonic crystal on the surface of a glass substrate. Structural color film, this kind of structural color purple film is bright in color and not easy to fade, but the preparation process of this method is complicated and requires more raw materials, which leads to the increase of preparation cost

[0004] Although there are a large number of Chinese invention patents on structural color rendering, there are few reports on the preparation method of carbon fiber woven surface coloring, especially the composite structural color material of carbon fiber woven cloth loaded with iron oxyhydroxide nanoparticles.
