Title:
COLORED PATTERNED COLOR-CHANGING FABRIC BASED ON ELECTRONIC INK, AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/070699
Kind Code:
A1
Abstract:
Disclosed in the present invention are a colored patterned color-changing fabric based on electronic ink, and a preparation method. The fabric comprises a conductive a fabric microstrip formed by means of weaving using conductive yarns and insulating yarns, wherein the conductive yarns form a conductive region, and the insulating yarns form an insulating region; an electronic ink microcapsule layer is arranged on the conductive region; a flexible transparent conductive layer is arranged on the electronic ink microcapsule layer; and a transparent polymer layer is arranged on the flexible transparent conductive layer. In the present invention, the surface layer of the microstrip is a conductive layer, and the bottom layer thereof is an insulating layer; an electrophoretic color-changing microcapsule, a conductive one-dimensional nanomaterial and a transparent polymer are uniformly applied to the surface of the microstrip, and a voltage which is output by means of a driving circuit is applied to the conductive microstrip and the transparent conductive layer, such that selective inverted color display of a centimeter-scale micro-region on the surface of the microstrip is realized. An upper electrode and a lower electrode are connected to a control circuit, such that centimeter-size pixel control and large-size graphic display are realized, and a foldable, high-environment-tolerance, low-cost and large-area color display and self-adaptive visible light camouflage fabric based on a conductive fabric base material is manufactured.
