Fabrication method and application of hydrophobic/light trapping fly-eye lens array with micro-nano double-level structure

Abstract

The invention discloses a manufacturing method and application of a hydrophobic / light-trapping fly-eye lens array with a micro-nano double-level structure, and relates to the fly-eye lens array and its manufacturing technology. The manufacture of the fly-eye lens array polymer product includes the following steps: manufacturing a flexible microlens array template; fixing the flexible microlens array template on the surface of the injection mold cavity, and molding the microlens array product by injection molding; pressing the microlens array on the product Print on the surface of ultra-pure aluminum foil, and then use anodic oxidation to form nanopores on the surface of the aluminum foil to obtain a fly-eye lens array template with a micro-nano dual-level structure; fix the fly-eye lens array template on the surface of the injection mold cavity, and use injection molding to form a fly-eye lens array artifacts. The surface of the fly-eye lens array product has a micro-nano dual-level structure, that is, it has a regular array of micro-lens arrays and a densely-arranged nano-column structure, thereby presenting hydrophobic and light-trapping properties.

Description

technical field [0001] The invention relates to a fly-eye lens array and its manufacturing technology, in particular to a method for manufacturing a fly-eye lens array with a micro-nano dual-level structure on the surface by injection molding technology so as to present a polymer product with hydrophobic and light-trapping properties and its application. Background technique [0002] With the continuous development of science and technology, miniaturization, integration, and arraying have become important directions for the development of optical systems. In the design and manufacture of micro-nano optical components, nature has given us many important inspirations, and the fly-eye lens array is a typical example of getting inspiration from the compound eyes of insects. The bionic fly-eye lens array has outstanding advantages such as large field of view, high sensitivity, and high integration, which largely makes up for the shortcomings of binocular vision such as small fiel...

Problems solved by technology

Most of the first four methods have problems such as cumbersome process, harsh conditions, high cost and narrow range of material selection, while the template method is considered to be an ideal method for large-scale preparation of fly-eye lens arrays.

However, how to manufacture complex micro-nano structure templates, accurately replicate the micro-nano structure of the template, and make the replicated micro-nano structure demould smoothly are the main challenges for large-scale manufacturing of fly-eye lens arrays.
