Abstract

The invention discloses a color graphical color-changing fabric based on electronic ink and a preparation method, the fabric comprises a conductive fabric micro-strip formed by weaving conductive yarns and insulating yarns, the conductive yarns form a conductive area, and the insulating yarns form an insulating area; 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. The surface layer of the micro-strip is a conductive layer, the bottom layer of the micro-strip is an insulating layer, the electrophoretic discoloration micro-capsule, the conductive one-dimensional nano-material and the transparent polymer are uniformly coated on the surface of the micro-strip, and the voltage outputted by the driving circuit is respectively applied to the conductive micro-strip and the transparent conductive layer, so that the selective turning color development of the centimeter-scale micro-area on the surface of the micro-strip is realized. The upper electrode and the lower electrode are connected with a control circuit, centimeter-size pixel control and large-size graph display are achieved, and the foldable, high-environment-tolerance, low-cost and large-area color display and self-adaptive visible light camouflage fabric based on the conductive fabric base material is manufactured.

Description

technical field [0001] The invention belongs to self-adaptive visible light color rendering fabric, in particular to an adaptive visible light color rendering fabric based on electronic ink and a preparation method. Background technique [0002] Functional fibers formed by endowing fiber materials with new properties can be used to prepare smart fabrics, among which color-changing fabrics provide a broad development space for large-scale dynamic graphics and text display, color-changing clothing, camouflage clothing, and weaponry camouflage cloth. [0003] Electronic ink display components have certain market advantages due to their low power consumption and high visibility under strong light, but their high price and low contrast limit their application scenarios. The use of conductive fabric as a substrate gives electronic ink new application opportunities, especially In low cost, large area display and dynamic camouflage scenarios. At present, the electronic ink display ...
