为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
可参考图2和图3，本发明实施例提供一种微纳结构制作方法，其具体制作步骤如下。Referring to FIG. 2 and FIG. 3 , an embodiment of the present invention provides a method for fabricating a micro-nano structure, and the specific fabrication steps are as follows.
第一步，在透光坯料的一侧表面粘附有一层液态并为透光材料且不会在重力作用下流离透光坯料的功能扩展料。In the first step, a layer of functional expansion material that is liquid and is a light-transmitting material and will not flow out of the light-transmitting blank under the action of gravity is adhered to one side surface of the light-transmitting blank.
功能扩展料为透光材料，可避免影响透光件800的基础功能实现，功能扩展料可为热固材料，也即是功能扩展料的温度达到预定温度时会发生固化相变，从液态相变为固体，也可以是紫外固化材料，也即是功能扩展料受到紫外线照射时会发生固化相变，从液态相变为固体。在本发明实施例中，功能扩展料为紫外固化材料，如此，功能扩展料在没有受到紫外线照射时，不会发生固化相变，避免环境温度对功能扩展料的干扰。The functional expansion material is a light-transmitting material, which can avoid affecting the realization of the basic functions of the light-transmitting member 800. The functional expansion material can be a thermosetting material, that is, when the temperature of the functional expansion material reaches a predetermined temperature, a solidification phase transition will occur, from a liquid phase. It can become a solid, or it can be a UV-curable material, that is, the functional extender will undergo a solidification phase change when it is irradiated by ultraviolet rays, from a liquid phase to a solid. In the embodiment of the present invention, the functional expansion material is an ultraviolet curing material. In this way, the functional expansion material will not undergo a solidification phase transition when it is not irradiated by ultraviolet rays, thereby avoiding the interference of the environmental temperature on the functional expansion material.
在此需要说明的是，此步骤中，功能扩展料整体呈薄膜状，且虽然功能扩展料为液态，但不会在重力作用下流离透光坯料，因此，功能扩展料的粘稠度较高。It should be noted here that in this step, the functional expansion material is in the form of a film as a whole, and although the functional expansion material is liquid, it will not flow out of the light-transmitting blank under the action of gravity, so the viscosity of the functional expansion material is relatively high. .
在具体实施中，功能扩展料可通过旋涂机涂覆于透光坯料In a specific implementation, the functional extension material can be coated on the transparent blank by a spin coater
第二步，将印章结构100压印功能扩展料，并使功能扩展料呈现出的形状为微纳结构810。In the second step, the stamp structure 100 is imprinted with a function extension material, and the shape of the function extension material is a micro-nano structure 810 .
其中，印章结构100朝向功能扩展料的侧面具有能够与微纳结构810嵌合的压嵌结构110，以在印章结构100压印功能扩展料时，使功能扩展料呈现出的形状为微纳结构810。Wherein, the side of the stamp structure 100 facing the functional expansion material has an embossing structure 110 that can be embedded with the micro-nano structure 810, so that when the stamp structure 100 imprints the functional expansion material, the shape of the functional expansion material is a micro-nano structure. 810.
在此步骤中，功能扩展料依然是液态，因此，功能扩展料受到印章结构100压印时会发生形变。In this step, the functional expansion material is still in liquid state, and therefore, the functional expansion material will be deformed when being stamped by the stamp structure 100 .
第三步，使功能扩展料固化，并附着于透光坯料，其中，透光坯料与呈微纳结构810状的功能扩展料共同构成透光件800。In the third step, the functional expansion material is cured and attached to the light-transmitting blank, wherein the light-transmitting blank and the functional expansion material in the shape of the micro-nano structure 810 together constitute the light-transmitting member 800 .
在功能扩展料成为透光件800的一部分时，功能扩展料呈微纳结构810状。When the functional expansion material becomes a part of the light-transmitting member 800 , the functional expansion material is in the shape of a micro-nano structure 810 .
在此需要说明的是，如功能扩展料为紫外固化材料（如，环氧丙烯酸酯），则在此步骤中，是通过紫外线使功能扩展料固化的。It should be noted here that, if the functional expansion material is an ultraviolet curing material (eg, epoxy acrylate), in this step, the functional expansion material is cured by ultraviolet rays.
第四步，使印章结构100与功能扩展料分离。The fourth step is to separate the seal structure 100 from the function expansion material.
此步骤中，功能扩展料不会粘附于印章结构100，避免破坏功能扩展料呈现出的微纳结构810。In this step, the functional extension material will not adhere to the stamp structure 100 to avoid damaging the micro-nano structure 810 presented by the functional extension material.
基于本发明的方法，透光件800的表面的微纳结构810可以一次成型，相对于现有技术，即相对于光刻、电子束直写或离子刻蚀的制作方法在透光件800的表面逐步形成，明显减少了制作时间，提高了在透光件800的表面制出微纳结构810的制作效率。Based on the method of the present invention, the micro-nano structures 810 on the surface of the light-transmitting member 800 can be formed at one time. The surface is gradually formed, which significantly reduces the fabrication time and improves the fabrication efficiency of fabricating the micro-nano structure 810 on the surface of the light-transmitting member 800 .
在本发明实施例中，在功能扩展料固化之前，使印章结构100压印功能扩展料的作用力维持恒定，如此，有利于保证印章结构100的压印效果。In the embodiment of the present invention, before the functional expansion material is cured, the force for imprinting the functional expansion material on the stamp structure 100 is kept constant, which is beneficial to ensure the imprinting effect of the stamp structure 100 .
