Embodiment 1

[0086] Methyl methacrylate: 2-hydroxyethyl acrylate: vinyl acetate: methylvinyldimethoxysilane was mixed in a ratio of 30:20:20:30, and a monodisperse water-based polymer emulsion was prepared by emulsion polymerization.

Embodiment 2

[0088] Butyl acrylate: methacrylic acid: styrene: methacrylamide was mixed in a ratio of 60: 10: 20: 10, and a monodisperse water-based polymer emulsion was prepared by a dispersion polymerization method, and water-based nano-titanium dioxide particles with a particle size of 4 nm were added. Stirring at 100 rpm for 60 minutes to prepare nanocomposite emulsion, the dosage of nano titanium dioxide particles is 10wt%.

Embodiment 3

[0090] Mix methylstyrene: perfluoropropyl vinyl ether and butyl acrylate in a ratio of 50:30:20, prepare a monodisperse water-based polymer emulsion by emulsion polymerization, add water-based nano barium titanate particles with a particle size of 50nm, Stirring at 500 rpm for 60 minutes to prepare a nano-composite emulsion, the amount of nano-barium titanate particles is 1 wt%.

Abstract

The invention belongs to fields of chemical industry, materials and optics, and relates to a structural color film material used in a large area and a method for preparing the same. Water-based inorganic nano-particles, monodisperse polymer emulsion and a non-essential addition agent are compounded by an in-situ polymerization method or blending method to obtain nano-composite emulsion, and the obtained emulsion is coated on the surface of a substrate; and moisture is volatilized, the three-dimensional ordered nano-structural color film material is prepared, and the color of the material can be regulated in a visible light area without adding any pigments. The structural color film material has the advantages of simple preparation, complete aquosity, safety, innocuity, easy large-area construction, good transparency, strong adhesive force and high heat resistance, can be directly coated on surfaces of glass, metal, ceramic, concrete, plastic and the like, and is used for bionics, decoration, printing, color display, photonic crystals, wave filtering, personal care, fabric fibers, coating, anti-counterfeit, optical sensors, photoelectric conversion materials and the like.

Description

technical field [0001] The invention belongs to the fields of chemical industry, material and optics, and relates to a film material with structural color. More specifically, the present invention relates to a large-area structural color film material comprising aqueous inorganic nanoparticles, a monodisperse polymer emulsion and optional additives. The invention also relates to the preparation method and application of the film material with structural color. Background technique [0002] The main way to produce color in nature is pigment, but structural color (Structural Color) does not require any pigment. It is the color produced by the interaction between natural light and microstructures with similar wavelength scales. Examples of structural colors that exist in nature include iridescent natural opals, peacock feathers, insects, sea creatures, etc., which are mainly used for animal self-protection, attracting the attention of similar animals, issuing warning signals, ...
