Example Embodiment

[0027] Example 1

[0028] Take steel beads having a diameter of 1 mm, which is tightly arranged on a glass plate, and the steel bead is fixed to the glass plate as a template with ultraviolet cured glue. The polydimethylsiloxane (PDMS) monomer and the curing agent are mixed uniform in mass than 25: 1, and the vacuum conditions are 30 min, and the prepolymer is spread on the glass plate, placed in an oven at 80 ° C. Curing 10 min, closely bonded to the steel ball template, 100 min under 100 ° C for 30min, remove the PDMS from the template, peeled from the glass plate to obtain a PDMS with a bowl array structure. Elastomer.

[0029] It is called 40.0 g of water, 1.0 g of hexadalkyltrimel bromide (CTAb) and 2.5 g of methyl methacrylate (MMA) and acrylamide (AM) mixed monomer (mass ratio 10: 1) In the reaction flask, stirring was stirred under nitrogen protection for 30 min. The water bath was heated to 75 ° C to add 45.0 mg of potassium sulfate (KPS) to the reaction bottle to react 1...

Example Embodiment

[0034] Example 2-4

[0035] The method is the same as in Example 1, but the diameter of a steel bead is prepared by a steel bead having a diameter of 3.0 mm, and a PDMS elastomer with a bowl structure is prepared.

Example Embodiment

[0036] Example 5-6

[0037] The method is in Example 1, but the silicon sheet and the quartz sheet are respectively carried out as a matrix as a matrix as a matrix.

Abstract

The invention relates to an iridescent-free structural color material and a preparation method thereof, belongs to the field of preparation of new materials and particularly belongs to the field of preparation of new color-producing materials. The invention relates to an iridescent-free structural color material which is a periodic multilayer film structural color material which is adhered to a bowl-shaped structure on the surface of a polymer elastomer and is formed by alternately stacking two materials with different refractive indexes. According to the iridescent-free structural color material, a problem of angle dependency of the periodic multilayer photonic film structure color can be well solved, and iridescent-free structural color materials with different colors can be prepared by controlling the layer thickness. The method is suitable for wide organic and inorganic materials, and has a good application prospect in the fields of naked eye detection, intelligent display and the like.

Description

technical field [0001] The invention belongs to the field of preparation of new materials, in particular to the field of preparation of new color-producing materials, in particular to a non-iridescent structural color material and a preparation method thereof. Background technique [0002] One-dimensional photonic multilayer film is a periodic micro-nano structure formed by alternating stacking of two materials with different refractive index along one direction. , will show a color visible to the naked eye, called structural color, and has extremely high application value in the fields of optical switches, filters, solar cells, and colorimetric sensing. One-dimensional periodic multilayer thin films have a wide range of material sources and easy-to-adjust optical properties, and have good application prospects in visual sensing and detection of environmental parameters. However, the highly ordered micro-nano structure not only endows the photonic film with color, but also ...
