Abstract

The invention provides a flexible electrochromic device and a manufacturing method thereof. The flexible electrochromic device includes a conductive layer, a color-changing layer and a conductive gel layer. The conductive layer has no substrate and can be freely bent, and the color-changing layer is arranged above the conductive layer. , the conductive gel layer is arranged above the color-changing layer. The present invention provides a flexible electrochromic device and a manufacturing method thereof. On the one hand, by using a grid structure without a substrate as a conductive layer, the thickness of the flexible electrochromic device is lower than that of the existing electrochromic device, and the improvement is improved. The conductivity and overall transmittance of the electrochromic device are improved, and the manufacturing cost is reduced; on the other hand, the present invention adopts a grid structure without a substrate as the conductive layer, and cooperates with the conductive gel layer, which can achieve far higher than the existing The degree of bending of the electrochromic device. In addition, the conductive gel layer itself has stickiness and can be adhered to the surface of most objects, thus realizing the applicability of the electrochromic device.

Description

technical field [0001] The invention relates to the technical field of flexible electrochromic devices, in particular to a flexible electrochromic device and a manufacturing method thereof. Background technique [0002] Electrochromism is a phenomenon in which the optical properties (reflectivity, transmittance, absorptivity, etc.) of a material undergo a stable and reversible color change under the action of an external electric field, which is manifested as a reversible change in color and transparency in appearance. Materials with electrochromic properties are called electrochromic materials, and devices made of electrochromic materials are called electrochromic devices. [0003] Electrochromic device refers to a device whose color can also change reversibly by coloring and fading under the action of alternating positive and negative voltages. Its application areas mainly include smart windows, display technology, military camouflage, flexible wearable devices and anti-g...
