Real-time dynamic color regulation and control micro device, method for preparing micro device and real-time dynamic color regulation and control method

Abstract

The invention discloses a real-time dynamic color regulation and control micro device, a method for preparing the micro device and a real-time dynamic color regulation and control method. The method for preparing the micro device comprises the following steps of: preparing a high-aspect-ratio polymethyl methacrylate (PMMA) two-dimensional microstructure array on a platinum layer by using a synchrotron radiation light source; depositing a lead zirconate titanate film layer in a microstructure by using direct current magnetron sputtering; and depositing a high-reflectivity nano metal chromium layer on the top of the micro structure to form an upper reflecting layer and a lower reflecting layer with height difference. By changing voltage between platinum and chromium, the height difference between the two reflecting layers is controlled in real time to make the micro device present different colors under the condition of natural light, thus the colors of the micro device are regulated and controlled dynamically. According to the real-time dynamic color regulation and control micro device, the method for preparing micro device and the real-time dynamic color regulation and control method, restriction of fixed size in the depth direction of the conventional microstructure array is broken, and the depth change of the microstructure can be controlled in real time by only changing the external voltage by using the inverse piezoelectric effect of a piezoelectric film material, so the colors of the micro device can be regulated and controlled dynamically without using any pigments. The real-time dynamic color regulation and control micro device is consistent with the environment-friendly theme and is expected to be widely used in the fields of optics, material science, printing industry, construction industry and the like.

Description

technical field [0001] The invention relates to a real-time color dynamic control micro-device and a preparation and control method thereof. Background technique [0002] In order to break through the application limitations of color pigments, pigment-free color control technology has attracted widespread attention, and has developed rapidly in recent years, with various principles. With the maturity of microstructure, especially the preparation process of micro-nano ordered array materials, coupled with its unique functions in optics, electricity, magnetism and mechanics, the use of microstructure to achieve color control has become a color control method without pigments. The mainstream solution of technology. At present, there are many studies on the use of microstructures to achieve color regulation. However, in the case of non-solution, since the size of the microstructure array is not variable, a microstructure array of one size can only correspond to a specific color...

Problems solved by technology

But for the nano-scale size, the deformation of PZT is very small, and it is not meaningful to directly use lead zirconate titanate materials to prepare microstructures.
