As described later in detail, the solution located in the receiving space 142a moves to the inner surface of the basket 142 by the centrifugal force.

Hereinafter, a method for manufacturing a photonic crystal using the above-described apparatus will be described in detail. A method of manufacturing a photonic crystal includes a polymer layer forming step of forming a polymer layer 100 having a predetermined thickness on the surface of the basket 142 by causing centrifugal force to move the polymer solution toward the surface of the basket 142, And a photonic crystal layer forming step of forming a photonic crystal layer 200 having a predetermined thickness on the surface of the polymer layer 100 by moving the colloidal solution containing the photonic nanoparticles toward the surface of the basket 142 , The surface of the basket 142 has a constant radius of curvature from the axis of rotation and a constant centrifugal force acts on the surface of the basket 142 and the surface of the polymer layer 100.

In the polymer layer forming step, the polymer solution is moved toward the surface of the basket 142 by the centrifugal force so that the polymer solution is applied to the surface of the basket 142 to a predetermined thickness, and then dried to form a polymer layer on the surface of the basket 142 The surface of the basket 142 has a certain radius of curvature r1 from the rotation axis 111 so that a constant centrifugal force acts on the surface of the basket 142 The polymer solution is applied to the surface of the basket 142 to a predetermined thickness. The polymer solution includes a liquid polymer and a curing agent, and various polymers may be used as the polymer, but polydimethylsiloxane is preferably used. Specifically, a polymer solution (for example, a polymer solution is formed in such a manner that the mass ratio of the PDMS and the curing agent is 10: 1) is poured through the communication hole 141b of the device 1 to insert the accommodating space 142a of the basket 142, The polymer solution is moved to the inner surface of the basket 132 by centrifugal force by rotating the basket 142 by operating the driving unit 111 (for example, 2000 to 3000 rpm) The polymer solution is applied to the inner surface of the basket 142 to a predetermined thickness. When the basket 142 is rotated for a predetermined time (for example, 1 to 2 days), the polymer solution is dried and cured, a polymer layer having a predetermined thickness (for example, 2 to 5 mm) is formed on the inner surface of the basket 142 as shown in FIG. When the polymer solution is introduced into the accommodation space 142a and the air in the accommodation space 142a is sucked into the vacuum state through the communication hole 141b, the time for drying and curing the polymer solution can be shortened.

In the photonic crystal layer forming step, after the polymer layer forming step, the colloidal solution containing the photo-nanoparticles moves toward the surface of the basket 142 by the centrifugal force, and the colloidal solution is coated on the surface of the polymer layer 100 to a predetermined thickness So that the photonic crystal layer 200 having a predetermined thickness is formed on the surface of the polymer layer 100. The surface of the polymer layer 100 has a predetermined radius of curvature r2 from the rotation axis 111, So that a uniform centrifugal force is applied to the surface of the polymer layer 100, and the colloidal solution is applied to the surface of the polymer layer 100 to a constant thickness. The light nanoparticle means a nanoparticle capable of forming a photonic crystal, and the structure color realized according to the type and size thereof is different. For example, polystyrene, silica, and melanin having a diameter of 200 to 300 nm may be used as the photo-nanoparticles, and the photo-nanoparticles may be dispersed in DI water A colloidal solution can be formed. Specifically, a colloidal solution (for example, a mixture of silica and deionized water) is poured through the communication hole 141b of the apparatus 1 to place the colloidal solution in the receiving space 142a of the basket 142 (For example, 2000 to 3000 rpm), the basket 142 is rotated to move the colloidal solution toward the inner surface of the polymer layer 100 by centrifugal force, When the basket 142 is rotated for a predetermined period of time (for example, about 24 hours), the optical nanoparticles are magnetically coupled when the concentration increases and the solvent evaporates, A photonic crystal layer 200 having a uniform lattice structure (opal structure) having a predetermined thickness can be formed on the inner surface of the polymer layer 100 as shown in FIG. 8 (b). When the colloidal solution is introduced into the accommodation space 142a and the air in the accommodation space 142a is sucked into the vacuum state through the communication hole 141b, the time for drying the colloidal solution can be shortened.

After the photonic crystal layer forming step, the hardening agent is moved toward the surface of the basket 142 by the centrifugal force so that the hardening agent is positioned in the gap of the photonic crystal layer 200, To thereby form a photonic crystal layer 300 of an inverse opal structure. Specifically, a hardening agent (for example, PEGDA) is poured through the communication hole 141b of the apparatus 1 to position the hardener in the receiving space 142a of the basket 142, and then the driving unit 111 is operated (For example, 2000 to 3000 rpm), the basket 142 rotates so that the curing agent moves toward the inner surface of the photonic crystal layer 200 by the centrifugal force, so that the curing agent is dispersed in the inner space of the photonic crystal layer 200 The basket 142 is maintained in a rotating state and is cured using a UV lamp. When the optical nanoparticles are melted and removed by hydrofluoric acid, as shown in FIG. 8 (c), the polymer layer The photonic crystal layer 300 having a uniform lattice structure (inverse opal structure) having a predetermined thickness can be formed on the inner surface of the substrate 100. Therefore, when the photonic crystal layer is formed only through the photonic crystal layer type step, the photonic crystal layer 200 having an opal structure is formed on the polymer layer 100. However, if the photocrystal layer processing step is further performed, (300) is formed.

The method of manufacturing the photonic crystal layer may include a step of moving the colloidal solution containing the photo-nanoparticles toward the surface of the basket 142 by a centrifugal force after the photonic crystal layer forming step or the photonic crystal layer processing step, 300), and then dried to form a photonic crystal layer (not shown) having a certain thickness on the surface of the photonic crystal layer 200 or 300 (hereinafter, referred to as 'second photonic crystal layer of an opal structure' And a photonic crystal layer addition forming step for forming a photonic crystal layer. Although not shown, when a photonic crystal layer addition forming step is performed after the photonic crystal layer processing step, a second photonic crystal layer of an opal structure is formed on the photonic crystal layer 200 of the opal structure, A second photonic crystal layer of an opal structure is formed on the photonic crystal layer 200 of the inverse opal structure. Since the additional photocrystal layer forming step is performed after the photonic crystal layer 200 or 300 is formed, the same steps as those of the photonic crystal layer forming step are performed, and thus a detailed description thereof will be omitted.

The method of manufacturing the photonic crystal layer may be such that after the photonic crystal layer is further formed, the curing agent moves toward the surface of the basket 142 by centrifugal force so that the curing agent is positioned in the gap of the second photonic crystal layer of the opal structure, And further removing the particles to form a second photonic crystal layer (not shown) of an inverse opal structure. Although not shown, a second photonic crystal layer having an opposite opal structure may be formed on the photonic crystal layer 200 of the opal structure through the additional crystal layer addition processing step, or a second photonic crystal layer having an opposite opal structure may be formed on the photonic crystal layer 200 having the opposite opal structure. One photonic crystal layer is formed. The additional photocrystal layer processing step is performed in the same manner as the photonic crystal layer processing step except that the second photonic crystal layer of the opal structure is formed, and thus a detailed description thereof will be omitted. Therefore, it is possible to manufacture the photonic crystal in which the photonic crystal layer of the opal structure and / or the inverse opal structure are laminated in order by continuously performing the photonic crystal layer forming step and the photonic crystal layer further processing step. It is also possible to control the type and size of the optical nanoparticles used for forming each photonic crystal layer so that the photonic crystals having a plurality of photonic crystal layers have a different structure color for each photonic crystal layer.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as belonging to the scope.
