A method for full-wing, high-fidelity, large-area microstructural replication of Lepidoptera insect wings

Abstract

The invention relates to a method for performing complete-wing-surface high-fidelity large-area microstructure copying on lepidopterous insect wings, which comprises the following steps: multiangular rotary vapor deposition of metal film, female mold making by selective chemical thick plating, plasma incineration removal on female mold surface, male mold making by high-precision plastic casting copying, and the like. The multiangular rotary vapor deposition process is adopted to deposit a metal film on the complete lepidopterous insect wing surface so as to capture and fix the slide-wedged small-inclination wing microstructure, thereby fully utilizing the advantages of fine crystal grain, favorable filling property, easy coating and the like, and being beneficial to ensuring the high fidelity of the subsequent chemical thick plating; and the chemical thick plating is performed after the microstructure capture and fixation to avoid many problems in the electroforming mold making method, thereby implementing complete-wing-surface large-area making of the complex-type female mold plate.

Description

technical field [0001] The invention relates to a method for large-area and high-fidelity replication of the complex microstructure of insect wings, more particularly, a method for replicating the full-surface, high-fidelity, and large-area microstructure of the wings of Lepidoptera insects. It belongs to the technical field of bionic manufacturing. Background technique [0002] Lepidoptera is the second largest order in Insecta after Coleoptera, including various butterflies and moths, with more than 40 superfamilies, more than 120 families and more than 180,000 species. The colors on the wings of Lepidoptera insects are divided into chemical colors and physical colors. Physical colors are also called structural colors, which refer to the anisotropic colors presented by the light characteristics of the microstructure itself. The wings of most Lepidoptera insects are composed of a translucent membrane and a number of tiny scales covering it. The surface of the scales is com...

AI Technical Summary

Problems solved by technology

[0003] However, although the above-mentioned patent achievements provide a certain reference value in the microstructure replication of butterfly wings, they are only limited to the microstructure replication of a single butterfly scale or small-area biological samples, and do not solve the problem of full-wing, high-fidelity, large-area microstructure. The problem of structural replication, and the solution of the above problems will help to promote the large-scale and industrial production of bionic devices or functional materials related to the wings of Lepidoptera insects
