Description

Technical Field

[0001] The present invention belongs to the technical field of new materials, and in particular relates to a color-developing material based on the color-forming principle of pheasant feather structural color and a preparation method thereof. Background Art

[0002] There are two main sources of color in nature: pigmentary colors, which are produced by the selective absorption of light by pigment molecules, and structural colors, which arise from the interaction between light and micro-nanostructures. Structural colors have the characteristics of high color saturation and good weather resistance.

[0003] Currently, structural color materials are generally three-dimensional photonic crystals. Three-dimensional photonic crystals are ordered arrays of monodisperse colloidal microspheres of approximately 160-280 nm. According to Bragg's theorem, the structural color they produce has obvious angle-dependent color changes, that is, different colors can be seen at different observation angles. However, traditional three-dimensional photonic crystal preparation has poor mechanical properties, and the color can only be observed at the specular angle of the incident light. The structural color disappears with a single change in the incident or observation angle, and gradually becomes dimmer as the observation angle increases. The single performance of three-dimensional photonic crystals makes them easy to imitate and fragile, which greatly limits their application.

[0004] The color rendering of bird feathers is a classic example of structural color. Current research on bird structural color design has largely been limited to peacocks and domestic pigeons, with little attention paid to pheasants. Pheasant feathers also display a vibrant color palette, with distinct characteristics that change color with viewing angle. Accurately simulating the color shift of pheasant feathers—specifically, the natural transition between green and purple—has become a pressing challenge.

[0005] To this end, it is urgent to develop a color-rendering material based on the structural color formation principle of pheasant feathers. Summary of the Invention

[0050] In order to better explain the present invention and facilitate understanding, the following is a detailed description of the present invention in conjunction with the accompanying drawings through specific embodiments. Figure 5 The orientation is referenced.

[0051] Example 1

[0052] Electron microscopy analysis (e.g. Figure 1 and Figure 2As shown in Figure 2, the microstructure of the structural colors in both pheasant blue and green feathers is a two-dimensional photonic crystal structure formed by melanin rods bound by keratin. In pheasant feathers, the vanes are composed of barbs and quills. Both barbs and quills of different colors possess a two-dimensional photonic crystal structure formed by melanin rods bound by keratin. The structural color of pheasant feathers is caused by light scattering caused by melanin rods arranged in keratin.

[0053] Furthermore, the applicant discovered that in the microstructure of the pheasant blue feather structural color and the pheasant green feather structural color, the melanin rods are arranged into independent honeycomb geometric structures (such as Figure 1 The third picture from left to right, Figure 2 The third picture from left to right, Figure 3 As shown in Figure 2), the microstructure of pheasant feathers can be attributed to a two-dimensional photonic crystal with cylindrical structures arranged in a hexagonal lattice, as shown in Figure 2. Figure 4 shown.

[0054] In addition, the applicant discovered through research that the reflectivity of the microscopic nanostructure of pheasant feathers will decrease when the incident angle (different viewing angles) exceeds a certain angle, and the reflectivity of the proximal area will increase. Therefore, as the illumination angle and / or observation angle increases, the brighter blue light band will shift from the outer area of ​​the feather to the inner area, explaining why the color of pheasant feathers changes with different observation angles.

[0055] Based on the aforementioned research on the microstructure of pheasant feathers, the applicant constructed a color-rendering material structure. To simulate the color changes of pheasants, they applied a structural color biomimetic design method to simulate the light refraction effects of the constructed color-rendering material's different structures. Specifically, they used Rhino 3D modeling software to parametrically model the color-rendering material structure. Using KeyShot ray tracing and global light rendering programs, they rendered the color of the color-rendering material structure and simulated the light refraction effects.

[0056] Through continuous experiments, we found that the color-developing material with the following structure can simulate the effect of pheasant feathers changing color with the viewing angle. Figures 5 to 7As shown, the constructed color-developing material structure includes a plurality of strip-shaped color-developing elements arranged in an array; each color-developing element includes a color information layer and a transparent layer 2, and the transparent layer 2 is located above the color information layer; the color information layer includes a rectangular transparent encapsulation body 11 and a pigment rod completely wrapped in the encapsulation body, the pigment rod includes at least two pigment sub-rods 14 of different colors, the pigment sub-rods 14 extend along the length direction of the color-developing element, and at least two pigment sub-rods 14 are arranged closely in sequence in the width direction of the color-developing element to form a pigment rod; the upper surface of the transparent layer 2 is an arched surface, and the lower surface of the transparent layer 2 is a plane, and the two arch feet of the arched surface are respectively connected to the two edges of the plane; the lower surface of the transparent layer 2 is connected to the upper surface of the transparent encapsulation body 11, and the transparent layer 2 covers the pigment rod.

[0057] In this configuration, the color-rendering element comprises a transparent layer 2 derived from the keratin cortex of a pheasant feather, a transparent encapsulating body 11 derived from the keratin medium used to bind melanin rods in pheasant feathers, and pigment rods 14 derived from melanin rods in pheasant feathers. At least two pigment rods 14 are arranged across the width of the color-rendering element to simulate the arrangement of melanin rods in pheasant feathers. Each pigment rod contains at least two pigment rods 14 of different colors, providing different pigment information. Combined with the special refractive and reflective properties of the specific shape of the transparent layer 2, this creates an optical color-changing effect similar to that of pheasant neck feathers. When light passes through the transparent layer 2 and strikes the pigment rods, the different colors presented by the pigment rods 14 are further modulated and mixed, producing a stunning color effect. In summary, the color-rendering element structure provided in this embodiment simulates the microstructure and color-changing mechanism of pheasant neck feathers.

[0058] It should be noted that various complex color patterns and gradient effects can be created by adjusting the color distribution of the pigment sub-rods 14 in the pigment rod.

[0059] Preferably, the pigment rod includes three pigment sub-rods 14 of different colors: a purple pigment sub-rod 14, a green pigment sub-rod 14, and a blue pigment sub-rod 14. These three sub-rods 14 are arranged closely together across the width of the color-rendering element. This allows for the simulation of the blue-green-purple color variations of a pheasant's neck feathers.

[0060] Preferably, the color information layer includes two pigment rods completely encapsulated within the package, namely a first pigment rod 12 and a second pigment rod 13, with the first pigment rod 12 located above the second pigment rod 13. All pigment sub-rods 14 in the first pigment rod 12 and all pigment sub-rods 14 in the second pigment rod 13 have the same shape and size. The pigment sub-rods 14 include a regular triangular prism and a semi-cylinder. The side plane of the semi-cylinder coincides with and is connected to one side surface of the regular triangular prism, and the edge of the regular triangular prism away from the semi-cylinder forms a taper of the pigment sub-rod 14. In the first pigment rod 12, the tapers of the three pigment sub-rods 14 are located at the same position, and the three pigment sub-rods 14 are arranged closely in sequence along the width direction of the color-rendering element. In the second pigment rod 13, the tapers of the three pigment sub-rods 14 are located at the same position, and the three pigment sub-rods 14 are arranged closely in sequence along the width direction of the color-rendering element. The side plane of the first pigment rod 12 coincides with the side plane of the second pigment rod 13. Thus, the first pigment rod 12 and the second pigment rod 13 are combined to form a hexagonal columnar structure, simulating the pattern of melanin rods in pheasant feathers arranged in a hexagonal lattice. Figure 8 shown.

[0061] More preferably, the purple pigment sub-rods 14 in the first pigment rod 12 are arranged opposite the purple pigment sub-rods 14 in the second pigment rod 13, the green pigment sub-rods 14 in the first pigment rod 12 are arranged opposite the green pigment sub-rods 14 in the second pigment rod 13, and the blue pigment sub-rods 14 in the first pigment rod 12 are arranged opposite the blue pigment sub-rods 14 in the second pigment rod 13. This allows for a more realistic simulation of the blue-green-purple color changes in the pheasant's neck feathers.

[0062] Preferably, the color-developing material includes a plurality of color-developing element groups arranged in an array, and the color-developing element group is formed by the plurality of color-developing elements being sequentially arranged along the width direction of the color-developing elements.

[0063] As an example, the color-developing material includes a plurality of color-developing element groups arranged in an array, with the color-developing element groups arranged at intervals. In this way, the color-developing material can be carried on a flexible material, such as cloth, to present a gorgeous color effect on the cloth.

[0064] Based on the structure of the color-developing material described in the example, the color-developing material structure was parametrically modeled with the help of Rhino three-dimensional modeling software, involving multiple key experimental variables, including: the number of elements in the element group, the structural spacing of the pigment rods between the elements, the structural spacing of the transparent layer 2 between the elements, the height of the transparent layer 2, the width of the transparent layer 2, and the number of hexagonal columnar structures arranged along the width direction in the element (the first pigment rod 12 and the second pigment rod 13 are combined to form a hexagonal columnar structure). By changing the experimental variables, the color-developing material structure was rendered and the light refraction effect was simulated through the KeyShot ray tracing and global light rendering program. Finally, a better color-developing material structure was obtained, and the structural parameters were expressed as follows: the number of elements in the element group was 3 to 7 (such as Figure 9 and Figure 10 The color effect is better, and the structural spacing of the pigment rods between the elements (such as Figure 11 and Figure 12 The smaller the size (as shown), the better the color effect. The structural spacing of the transparent layer 2 between the elements (as shown) Figure 13 and Figure 14 The smaller the transparent layer 2 is, the better the color effect is. The aspect ratio of the transparent layer 2 is 0.5 to 1 (as shown in FIG. Figure 15 and Figure 16 The color effect is better, and the number of hexagonal columnar structures arranged along the width direction in the element is 1 or 2 (as shown in Figure 17 and Figure 18 The color effect is better.

[0065] Furthermore, the color effect presented is the best when the number of elements in the element group is 6; the two arch feet of the arched surface of the transparent layer 2 are smoothly connected to the two edges of the upper surface of the transparent encapsulation body 11, and at this time, the structural spacing of the transparent layer 2 between the elements is 0, and the color effect presented is the best; the color effect presented is the best when the number of hexagonal columnar structures arranged along the width direction in the element is 1.

[0066] Furthermore, the transparent layer 2 is 15-18 mm long, 4.5-6.5 mm wide, and 6.5-9 mm high. The hexagonal columnar structure is 15-18 mm long, 4.5-6.5 mm wide, and 4.5-6.5 mm high. The minimum distance between each surface of the transparent encapsulation 11 and the pigment rod is 0.01-0.5 mm. A color-rendering element with these structural parameters produces excellent color effects.

[0068] This embodiment provides a method for preparing a color-developing material based on the color-forming principle of pheasant feather structural color, comprising the following steps:

[0069] (1) Modeling was performed according to the structure of the color-rendering element in Example 1. Multiple color-rendering elements were sequentially arranged along the width direction of the color-rendering elements to form a color-rendering element group. The color-rendering element groups were spaced apart to form an array, and a structural model of a color-rendering material based on the principle of color formation of pheasant feather structural color was obtained. The number of elements in the element group was 6. The two arch feet of the arched surface of the transparent layer 2 were smoothly connected to the two edges of the upper surface of the transparent encapsulation body 11. The number of hexagonal columnar structures arranged along the width direction within the element was 1. The transparent layer 2 was 16 mm long, 5.5 mm wide, and 7.5 mm high. The hexagonal columnar structure was 16 mm long, 5.5 mm wide, and 5.5 mm high. The minimum distance between each surface of the transparent encapsulation body 11 and the pigment rod was 0.05 mm.

[0070] (2) Using Stratasys full-color 3D printing technology, the pigment rod is printed with a colored photosensitive polymer material, and the transparent encapsulation body 11 and the transparent layer 2 are printed with a transparent photosensitive polymer material; after printing, the printed material is cured under ultraviolet light to obtain a color-developing material based on the color formation principle of pheasant feather structural color.

[0071] It should be noted that, in addition to using 3D printing technology to manufacture color-developing materials, laser sintering technology or fused deposition modeling technology can also be used to manufacture color-developing materials.

[0072] Example 3

[0073] This embodiment provides a color-developing material based on the color-forming principle of pheasant feather structural color. The main difference between this embodiment and Example 1 is that:

[0074] like Figure 19 and Figure 20 As shown, the color rendering element contains a pigment rod. The pigment rod comprises a purple pigment sub-rod 14, a green pigment sub-rod 14, and a blue pigment sub-rod 14, all of which are rectangular. The purple pigment sub-rod 14, the green pigment sub-rod 14, and the blue pigment sub-rod 14 are arranged closely together across the width of the color rendering element to form a rectangular pigment rod. This can also simulate the effect of the pheasant's neck feathers changing color as the viewing angle changes.

[0075] The rest of the contents are the same as those in Example 1 and will not be repeated here.

[0076] Example 4

[0077] This embodiment provides a color-developing material based on the color-forming principle of pheasant feather structural color. The main difference between this embodiment and Example 1 is that:

[0078] like Figure 21 and Figure 22As shown, the color rendering element contains a pigment rod, which includes three different colored pigment sub-rods 14: a purple pigment sub-rod 14, a green pigment sub-rod 14, and a blue pigment sub-rod 14. These three sub-rods 14 are arranged closely together across the width of the color rendering element. Within a color rendering element group formed by multiple color rendering elements arranged closely together across the width of the element, pigment sub-rods 14 of the same color are arranged to form a predetermined geometric pattern. This can also simulate the effect of the pheasant's neck feathers changing color as the viewing angle changes.

[0079] Specifically, in the color rendering element group, the blue pigment rods are arranged to form a rectangle, the green pigment rods are arranged to form a diamond, and the purple pigment rods are arranged to form an ellipse.

[0081] Example 5

[0082] This embodiment provides a color-developing material based on the color-forming principle of pheasant feather structural color. The main difference between this embodiment and Example 1 is that:

[0083] like Figure 23 and Figure 24 As shown, each color-rendering element further comprises a first hemispherical portion and a second hemispherical portion. The bottom plane of the first hemispherical portion overlies the first end surface of the color-rendering element, covering the transparent layer 2 and the pigment rod. The hemispherical edge of the first hemispherical portion smoothly transitions to the edge of the arched surface of the transparent layer 2. The bottom plane of the second hemispherical portion overlies the second end surface of the color-rendering element, covering the transparent layer 2 and the pigment rod. The hemispherical edge of the second hemispherical portion smoothly transitions to the edge of the arched surface of the transparent layer 2. This can also simulate the effect of the pheasant's neck feathers changing color as the viewing angle changes.

[0084] The first hemispherical portion is hemispherical or hemispherical, or has other shapes similar to a hemispherical shape; the second hemispherical portion is hemispherical or hemispherical, or has other shapes similar to a hemispherical shape.
