Embodiment 1

[0027] ① Prepare a tin dioxide inverse protein structure color film with a pore size of 217nm by the template method, as follows: add the tin dioxide precursor dropwise on the polystyrene template and let it infiltrate naturally; place it in a muffle furnace after the solvent evaporates Calcination is carried out to obtain the anti-protein structure color film.

[0028] The polystyrene template is prepared by emulsion polymerization. The specific preparation method is: weigh 0.035g of sodium lauryl sulfate and dissolve it in 135ml of deionized water, stir at 300r / min in a 250ml three-necked flask; heat in a water bath to 85 After the temperature stabilized, 15 g of styrene monomer was added; after 15 minutes, 0.15 g of potassium persulfate was added, and stirred at 85 °C for 5 hours. The obtained emulsion is heated and convectively self-assembled on the substrate on a heating plate at 70°C to obtain an opal-structured polystyrene template.

[0029] ②Put the PDMS monomer and c...

Abstract

The invention relates to a strength enhanced type low angle dependency structure color material and a preparation method thereof, in particular to a preparation method of the strength enhanced type low angle dependency structure color material, and belongs to the preparation field of color generation materials. The strength enhanced type low angle dependency structure color material consists of aninverse opal photonic crystal and an elastomer filled in protein structure gaps of the inverse opal photonic crystal, wherein the elastomer comprises polydimethylsiloxane, polyurethane, polysulfide rubber and polybutadiene rubber. The method is low in cost, simple and practicable, provides more possibilities for structure color materials in actual application, and especially has wide applicationprospects in the coloring field of building and packaging materials.

Description

technical field [0001] The invention relates to an intensity-enhanced low-angle-dependent structural color material and a preparation method thereof, in particular to a method for preparing an intensity-enhanced low-angle-dependent structural color material, and belongs to the field of color-producing materials. Background technique [0002] Photonic crystals are divided into opal structure and inverse opal structure. Due to its large specific surface area, strong charge transport ability, and controllable size, the inverse opal structure has drawn more and more attention from researchers. Usually, the inverse opal structure is prepared by the template method. Using the opal structure as a template, the precursor is filled into the pores of the opal structure, and then the template is removed to obtain the corresponding inverse opal structure. Based on the advantages of the inverse opal structure, it can meet more application fields. For example, Song Hongwei of Jilin Unive...
