Abstract

The invention discloses a preparation method for a stretchable electronic device with a regular corrugated structure, and belongs to the technical field of photoelectron. The method comprises the steps: preparing a roller with the surface being provided with a bar-shaped microstructure through the technologies of machining, 3D printing or injection molding; carrying out the evaporation of a metal film on the surface of an elastic film through employing the vacuum evaporation technology, and enabling the metal film to serve as a metal spacing layer; finally enabling a flexible thin film electronic device to be pasted on the surface of the elastic film through employing the roller rotation technology, and preparing the stretchable electronic device with the regular corrugated structure. The method provided by the invention is suitable for flexible thin-film electronic devices which are made of different materials and have different thicknesses and functions, can control the shape and appearance of corrugations, is low in preparation cost, is high in speed, is high in production efficiency, is uniform and stable in performance, and thereby is suitable for commercialized production.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and specifically relates to a method for preparing a stretchable electronic device with a regular wrinkled structure, using a roller wheel with a microstructure on the surface to control the combination of an ultra-thin flexible electronic device and an elastic film to form a regular wrinkled structure, Furthermore, the problem of incompatibility between the preparation process and device performance encountered in the large-scale production and commercial application of stretchable electronic devices based on wrinkled structures is solved. [0002] technical background [0003] In recent years, with the development of the electronics industry, stretchable electronic devices have gradually entered people's field of vision. Compared with traditional devices based on hard materials such as silicon and glass, stretchable electronic devices are flexible, bendable and stretchable, so they are s...
