Abstract: Electronic-ink-based colorful patterned color-changing fabrics and preparation methods thereof are provided. The fabric includes a conductive fabric microstrip formed by weaving using conductive yarn and insulating yarn. The conductive yarn forms a conductive region, and the insulating yarn form an insulating region. An electronic ink microencapsule layer is arranged on the conductive region. A flexible transparent conductive layer is arranged on the electronic ink microencapsule layer. A transparent polymer layer is arranged on the flexible transparent conductive layer. A surface layer of the microstrip is a conductive layer, and a bottom layer of the microstrip is an insulating layer. An electrophoretic color-changing microencapsule, a conductive one-dimensional nanomaterial, and a transparent polymer are uniformly coated on a surface of the microstrip, and a voltage output by a drive circuit is respectively applied to the conductive microstrip and the transparent conductive layer to achieve selective flip and color rendering of centimeter-scale micro-region on the surface of the microstrip. Upper and lower electrodes are connected with a control circuit to achieve centimeter-scale pixel control and large-size graphic display and make a conductive-fabric-substrate-based foldable, high-environmental tolerant low-cost large-area color display and adaptive visible light camouflage fabric.
