A non-close-packed silica ring nanoarray and its preparation method

Abstract

The invention discloses a non-close-packed silicon dioxide ring nano-array and a preparation method thereof, comprising: cleaning the quartz sheet, drying the cleaned quartz sheet, and then placing it in an ultraviolet ozone cleaning machine for irradiation. Then, a clean quartz sheet with a hydrophilic surface was prepared; a tightly arranged array of single-layer polystyrene colloidal balls was prepared on the surface of the clean quartz sheet by using the gas-liquid interface self-assembly method; the single-layer polystyrene colloidal array on the quartz sheet The ball array is a template, and a layer of silver film is deposited on the surface of the template by magnetron sputtering deposition method; the single-layer polystyrene colloidal ball array with the silver film deposited on the surface is heat-treated to obtain a silver nanometer on the quartz substrate. Particle arrays; the silver nanoparticle arrays on the quartz substrate were soaked in nitric acid to remove the silver nanoparticles, thereby making non-close-packed silica ring nanoarrays. The invention not only has high mechanical strength and firmness of the nanometer array, but also has simple preparation process, low cost and low requirements for equipment.

Description

technical field [0001] The invention relates to the field of silicon dioxide nanometer materials, in particular to a non-close-packed silicon dioxide ring nanoarray and a preparation method thereof. Background technique [0002] In the past ten years, nanomaterials have been widely used in production and life. From the perspective of nanodevices, nanoscale volumes not only facilitate the integration with existing technologies, but also exhibit many unique and excellent new physical properties. Arranging nanoparticles in a specific way can form an ordered nanostructure array, which is one of the important solutions for constructing nanodevices. Controllable two-dimensional nanostructure arrays and micropatterns are very important for the manufacture of micro-nano optoelectronic devices, sensors and biological devices. Chips are important. [0003] SiO 2 Nanomaterials have superior optical properties, and their array structures have been widely used in the field of optics. ...

AI Technical Summary

Problems solved by technology

For example, SiO can be assembled by electrostatic self-assembly 2 Nanoparticles are assembled on different optical devices as solar anti-reflection coatings, but the mechanical strength and firmness of this electrostatic self-assembled nanoparticles are poor; or they can be directly deposited on silicon dioxide by electron beam etching or laser etching. Build a microarray structure on a substrate, but this process is complex, costly, and requires high equipment

In addition, it was found through investigation that SiO has not been constructed in the prior art 2 Therefore, it is urgent to provide a preparation method with simple process, low cost and low equipment requirements to prepare SiO with high mechanical strength and firmness. 2 ring nanoarray
