Description

Technical Field

[0001] The 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: one is pigment color based on the selective absorption of light by pigment molecules, and the other is structural color originating from the interaction between light and micro-nano structures. Structural color has the characteristics of high color saturation and good weather resistance.

[0003] At present, structural color materials are generally three-dimensional photonic crystals. Three-dimensional photonic crystals are ordered arrays assembled from monodisperse colloidal microspheres of about 160-280nm. According to Bragg's theorem, the structural color produced has obvious angle-dependent color change characteristics, that is, different colors can be seen at different observation angles. However, the mechanical properties of traditional three-dimensional photonic crystals are very poor, and the color can only be observed at the mirror angle of the incident light. The structural color disappears when the incident or observation angle is changed, and as the observation angle increases, the structural color gradually becomes dim. Three-dimensional photonic crystals have single properties, are easy to imitate, and are easy to break, which greatly limits their application.

[0004] The color rendering of bird feathers is a typical structural color phenomenon. Currently, most of the research on bird structural color design is limited to peacocks and domestic pigeons, and no attention has been paid to pheasants. The color rendering of pheasant feathers is also a typical structural color phenomenon, with gorgeous colors, and pheasant feathers have the obvious characteristic of changing color as the viewing angle changes. How to accurately simulate the color change of pheasant feathers, that is, how to accurately simulate the characteristic of pheasant feathers changing color as the viewing angle changes, specifically the natural transition of pheasant feathers between green and purple, has become an urgent problem to be solved.

[0005] Therefore, 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 present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 5 The orientation is used as a reference.

[0051] Example 1

[0052] Electron microscopy analysis (e.g. Figure 1 and Figure 2As shown in the figure, the microstructures of the blue and green pheasant feather structural colors are both: a two-dimensional photonic crystal structure formed by melanin rods attached to keratin. In pheasant feathers, the feathers are composed of barbels and barbs. The barbels and barbs of different colors all have a two-dimensional photonic crystal structure formed by melanin rods attached to 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 to form 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 a cylindrical structure arranged in a hexagonal lattice, such as Figure 4 shown.

[0054] In addition, the applicant has 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 above research on the microstructure of pheasant feathers, the applicant constructed the structure of the color-rendering material. In order to simulate the color changes of pheasants, the structural color bionic design method was used to simulate the light refraction effect of different structures of the constructed color-rendering material. Specifically, the color-rendering material structure was parametrically modeled with the help of Rhino 3D modeling software, and the color rendering and light refraction effect of the color-rendering material structure were simulated through KeyShot ray tracing and global light rendering programs.

[0056] Through continuous experiments, it was 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 transparent encapsulation body 11 in a rectangular shape and a pigment rod completely wrapped in the encapsulation body, and the pigment rod includes at least two pigment sub-rods 14 of different colors, and 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 the color-rendering element thus configured, the transparent layer 2 is evolved from the keratin cortex of pheasant feathers, the transparent encapsulation body 11 is evolved from the keratin medium used to adhere melanin rods in pheasant feathers, the pigment sub-rods 14 are evolved from the melanin rods of pheasant feathers, at least two pigment sub-rods 14 are arranged in the width direction of the color-rendering element to simulate the arrangement pattern of melanin rods of pheasant feathers, and a pigment rod contains at least two pigment sub-rods 14 of different colors to provide different pigment information. At the same time, with the special refraction and reflection characteristics of the specific shape of the transparent layer 2, an optical color-changing effect similar to that of the pheasant neck feathers can be created. When light passes through the transparent layer 2 and shines on the pigment rods, the different colors presented by the pigment sub-rods 14 will be further modulated and mixed, thereby producing amazing color effects. In summary, the color-rendering element structure provided in this embodiment simulates the microstructure and color change mechanism of the 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, namely, a purple pigment sub-rod 14, a green pigment sub-rod 14 and a blue pigment sub-rod 14, which are arranged closely in sequence in the width direction of the color display element to form a pigment rod. In this way, the blue-green-purple color change of the pheasant's neck feathers can be simulated.

[0060] Preferably, the color information layer includes two pigment rods completely wrapped in the package, namely, a first pigment rod 12 and a second pigment rod 13, and the first pigment rod 12 is located above the second pigment rod 13; all the pigment sub-rods 14 in the first pigment rod 12 and all the pigment sub-rods 14 in the second pigment rod 13 have the same shape and size, and 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 cone of the pigment sub-rod 14; in the first pigment rod 12, the cones 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 in the width direction of the color display element; in the second pigment rod 13, the cones 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 in the width direction of the color display element; the side plane of the first pigment rod 12 coincides with the side plane of the second pigment rod 13. In this way, the first pigment rod 12 and the second pigment rod 13 are combined to form a hexagonal columnar structure, simulating the pattern in which the melanin rods of pheasant feathers are arranged in a hexagonal lattice. Figure 8 shown.

[0061] Further preferably, the purple pigment sub-rod 14 in the first pigment rod 12 is arranged opposite to the purple pigment sub-rod 14 in the second pigment rod 13, the green pigment sub-rod 14 in the first pigment rod 12 is arranged opposite to the green pigment sub-rod 14 in the second pigment rod 13, and the blue pigment sub-rod 14 in the first pigment rod 12 is arranged opposite to the blue pigment sub-rod 14 in the second pigment rod 13. In this way, the simulation of the blue-green-purple color change of the pheasant neck feathers is more realistic.

[0062] Preferably, the color-developing material comprises a plurality of color-developing element groups arranged in an array, and the color-developing element group is formed by a plurality of color-developing elements being sequentially arranged in a bonded manner along a 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, and the color-developing element groups are arranged at intervals. In this way, the color-developing material can be carried on a flexible material, such as a 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 3D 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 is rendered and the light refraction effect is simulated through the KeyShot ray tracing and global light rendering programs. Finally, a better color-developing material structure is obtained, and the structural parameters are expressed as follows: the number of elements in the element group is 3 to 7 (such as Fig. 9 and Fig.10 The color effect is better, and the structural spacing of the pigment rods between the elements (such as Fig.11 and Fig.12 The smaller the size of the transparent layer 2, the better the color effect. Fig.13 and Fig.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. Fig.15 and Fig.16 The color effect presented is better, and the number of hexagonal columnar structures arranged along the width direction in the element is 1 or 2 (as shown in Fig.17 and Fig.18 The color effect presented 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, and the minimum distance between each surface of the transparent encapsulation body 11 and the pigment rod is 0.01-0.5 mm. The color rendering element with such structural parameters has a better color effect.
