Embodiment 1

[0045] The poly(styrene-methyl methacrylate-acrylic acid) monodisperse latex particles (particle size) with a hard core-soft shell structure prepared by the previous patent application method at a concentration of 10wt% at room temperature (25°C) It is 210nm, the shell thickness is 35nm, it has obvious core-shell structure, see figure 1 ) Is added to a container with an air spray gun, and the monodisperse colloidal particle water dispersion is sprayed on the glass substrate through the air spray gun. After the water in the dispersion is volatilized under the action of the gun body gas, it will Obtained monodisperse polymer latex particles (poly(styrene-methyl methacrylate-acrylic acid)) on the surface of the substrate to form a colloidal three-dimensional photonic crystal film that is periodically arranged and orderly stacked in a face-centered cube; After drying, the film is peeled from the substrate to obtain a polymer colloidal photonic crystal film with a photonic band gap in...

Embodiment 2

[0047] The monodisperse poly(styrene-methyl methacrylate-acrylic acid) with a hard core-soft shell structure prepared by the method of the previous patent application at a concentration of 15wt% at room temperature (particle size of 244,191 nm, respectively) ) Is added to a container with an air spray gun, and the water dispersion of monodisperse polymer latex particles is sprayed on the glass substrate through the air spray gun. After the dispersion is volatilized under the action of the gun body gas, The monodisperse polymer latex particles are formed on the surface of the substrate to form a colloidal three-dimensional photonic crystal film that is periodically arranged and orderly stacked in a face-centered cube; after the coating is dried, the film is peeled from the substrate to obtain The polymer colloidal photonic crystal film with the photonic band gap in the visible region, image 3 (b) and image 3 (c) Scanning electron micrographs of the coating film obtained by air sp...

Embodiment 3

[0049] The monodisperse poly(styrene-methyl methacrylate-acrylic acid) with a hard core-soft shell structure prepared by the method of the previous patent application at a concentration of 19% by weight at room temperature (particle size 280,270, respectively) 244, 216, 204, 191, 173 nm) water dispersion is added to a container with an air spray gun, and the water dispersion of monodisperse polymer latex particles is sprayed on the paper or stainless steel plate substrate through the air spray gun. After the dispersion is volatilized under the action of the gun body gas, monodisperse polymer latex particles are obtained to form a colloidal three-dimensional photonic crystal film that is periodically arranged and orderly arranged on the surface of the substrate and stacked in face-centered cubes; After drying, the film is peeled from the substrate to obtain a polymer colloidal photonic crystal film with a photonic band gap in the visible region.

Abstract

The invention belongs to the preparation and application technical field of a colloid photon crystal film, in particular relating to a method which adopts a spray coating method to realize simple, quick and large-area preparation of the polymer colloid photon crystal film. The method comprises the following steps that: monodisperse polymer latex particle with a hard nucleus-soft structure shell is dispersed in water at normal temperature; then, the obtained monodisperse polymer latex particle dispersion liquid is packed in a container with a common air spray gun; the spray gun is aimed at a selected leveled off base material to carry out spray coating; when the moisture in the monodisperse polymer latex particle is volatized under the action of gun body gas, a colloid photon crystal film is formed by the monodisperse polymer latex particle piling up on the surface of the base material in a face-centered cubic; and after a coated film is dried, a large area of polymer colloid photon crystal film with a photon band gap and in a visible region or an ultraviolet region can be obtained.

Description

Technical field [0001] The invention belongs to the technical field of preparation and application of colloidal photonic crystal films, and particularly relates to a method for preparing a polymer colloidal photonic crystal film with a simple, rapid, and large-area spraying method. Background technique [0002] The colloidal photonic crystal material has a periodic structure formed by the regular arrangement of monodisperse latex particles to achieve special control of light by refraction or diffraction of light. Depending on the size of the periodic arrangement, the wavelength of the regulated light is different. Correspondingly prepared colloidal photonic crystal films have different application fields. In common patent documents, colloidal photonic crystal films are mainly used in filters (such as CN: 01105105.1, CN: 98110990.X), optical switches (CN: 02160207.7), and optical waveguides (CN: 02804125.9, CN: 99810798, CN: 01132293.4, CN: 02811132.X), optical fiber (CN: 00803964...
