Abstract

The invention provides a periodic SiO2 flaky nano structure. The length of the periodic SiO2 flaky nano structure is 125-130 mu m, the width of the periodic SiO2 flaky nano structure is 65-70 mu m, the tail end of the periodic SiO2 flaky nano structure is provided with 4-5 sawteeth, the surface of the periodic SiO2 flaky nano structure is of a periodically distributed strip-shaped structure, and the distribution period of the strip-shaped structure is 2.6-3 mu m. The invention also provides a preparation method of the periodic SiO2 flaky nano structure. The periodic SiO2 flaky nano structure is prepared by utilizing a sol-gel method by taking a butterfly wing as a template and tetraethoxysilane as a raw material. The periodic SiO2 flaky nano structure can be subjected to large-scale preparation on a glass slide, has the characteristics of good periodicity and regular topography, and can be applied to special gratings or other optical devices and the like in the field of optics.

Description

technical field [0001] The invention relates to the technical fields of optical materials, biological nanomaterials and devices, in particular to a periodic SiO 2 Scale-like nanostructures and methods for their preparation. Background technique [0002] There are many kinds of organisms in nature with different shapes, and many organisms have very peculiar shapes and structures in their own tissues. These morphology and structures of biological tissues have attracted the attention of many researchers in recent years. At present, quite a lot of biological tissues, such as: leaves, beetle elytra, silk, wood, butterfly wings, human and dog hair have been used as templates to prepare various nanomaterials. These nanostructure replicas show good performance in some specific fields. [0003] Among all biomaterial templates, butterfly wings have attracted the attention of quite a few researchers because of its unique structure, soft texture, and relatively complex photonic cryst...
