Problems solved by technology

With the progress of society and the development of science and technology, people's pursuit of color is getting higher and higher, and the traditional color rendering methods can no longer meet the actual needs.
For example, dyes, pigments, paints, etc., which are widely used in printing, printing and dyeing industries, are colored by pigment colors. Although they play a huge role in people's daily life, there are also some problems. The acquisition of color cannot be achieved by traditional dye colors; moreover, saturation and lightness are a pair of contradictions in the color attributes that characterize color perception, that is, it is difficult to achieve high brightness and high saturation at the same time; traditional color rendering Technology is facing great challenges and tests

Embodiment 1

[0073] In this example, the vertical deposition method is used to prepare butterfly wing / colloidal crystal microsphere composite structural color film, and the specific steps of the method include:

[0074] Step 1: Select the Morphobis butterfly wing 3 with a periodic structure as a template, and perform surface pretreatment on the butterfly wing. First, degreasing treatment: the sample was repeatedly rinsed with physiological saline (0.65% Nac1 solution), fixed with 3% glutaraldehyde, and ultrasonically treated for 4 minutes to remove the dirt attached to the surface; then dehydration treatment: the degreased sample After taking it out, it was dehydrated with ethanol series. The ethanol concentrations used were 40%, 50%, 70%, pure ethanol, soaked for 10 minutes at each stage, and the samples were dried naturally.

[0075] Step 2: Prepare 2.5 mL of polystyrene microsphere dispersion (colloidal crystal micro 2) with a particle size of 350 nm and a mass concentration of 5%, and ...

Embodiment 2

[0081] In this example, the butterfly wing / colloidal crystal microsphere composite structural color film is prepared in batches by vertical deposition method, as shown in Figure 4 As shown, it is a schematic diagram of the imitation butterfly wing structure prepared in batches in this embodiment, wherein, 3 is the butterfly wing of the Morpho butterfly, 4 is the PDMS film, and 5 is the glass substrate. The butterfly wing of the great blue morpho butterfly has a whole wing structure, and the ratio of PDMS prepolymer to curing agent is 10:1.

[0082] The concrete steps of this method include:

[0083] Step 1: Select the Morphobis butterfly wing 3 with a periodic structure as a template, and perform surface pretreatment on the butterfly wing. First, degreasing treatment: the sample was repeatedly rinsed with physiological saline (0.65% Nac1 solution), fixed with 3% glutaraldehyde, and ultrasonically treated for 4 minutes to remove the dirt attached to the surface; then dehydrat...

Embodiment 3

[0090] In this example, the vertical deposition method is used to prepare butterfly wing / colloidal crystal microsphere composite structural color film, and the specific steps of the method include:

[0091] Step 1: Select the Morphobis butterfly wing 3 with a periodic structure as a template, and perform surface pretreatment on the butterfly wing. First, degreasing treatment: the sample was repeatedly rinsed with physiological saline (0.65% Nac1 solution), fixed with 3% glutaraldehyde, and ultrasonically treated for 4 minutes to remove the dirt attached to the surface; then dehydration treatment: the degreased sample After taking it out, it was dehydrated with ethanol series. The ethanol concentrations used were 40%, 50%, 70%, pure ethanol, soaked for 10 minutes at each stage, and the samples were dried naturally.

[0092] Step 2: Prepare 2 mL of silica microsphere dispersion (colloidal crystal micro 2) with a particle size of 300 nm and a mass concentration of 3%, and dispers...

Abstract

The invention relates to a method for preparing a butterfly wing / colloid crystal microsphere composite structural color film by a vertical deposition method, and belongs to the technical field of structural color film preparation. The butterfly wing with periodic structure was selected as a template, and the surface of the butterfly wing was pretreated; the colloidal crystal microsphere dispersion liquid was prepared and ultrasonically dispersed to make it in a uniformly dispersed state; after the butterfly wing was cut, it was placed vertically In the petri dish, slowly add the microsphere dispersion to completely submerge the butterfly wings, then place the petri dish in a constant temperature and humidity box, and assemble it by vertical deposition method. After the solvent is completely evaporated, butterfly wings / colloidal crystals are obtained The microsphere composite structure achieves specific color rendering effects in different viewing directions. The invention also discloses a batch preparation method of the film. The invention can realize structural color display with wide color gamut, narrow band gap, high brightness and special color rendering effect, and not only has important scientific research value, but also has great application value.

Description

technical field [0001] The invention relates to a preparation method of a composite structural color film, in particular to a method for preparing a butterfly wing / colloid crystal microsphere composite structural color film with a special color rendering effect by using a vertical deposition method, and belongs to the technical field of structural color film preparation. Background technique [0002] Color is a visual perception that is closely related to the radiation of light, the interaction of objects with light, and the observer. With the progress of society and the development of science and technology, people's pursuit of color is getting higher and higher, and the traditional color rendering methods can no longer meet the actual needs. For example, dyes, pigments, paints, etc., which are widely used in printing, printing and dyeing industries, are colored by pigment colors. Although they play a huge role in people's daily life, there are also some problems. The acqu...
