A fabric includes a first flexible fabric layer, having fabric emissivity properties in a visible radiation range that are selected so as to mimic ambient emissivity properties of a deployment environment of the fabric, and at least one second flexible fabric layer, which is joined to the first flexible fabric layer, and which is configured to scatter long-wave radiation that is incident on the fabric. The first and second flexible fabric layers are perforated by a non-uniform pattern of perforations extending over at least a part of the fabric.

A shading device for a greenhouse includes a shading element and at least one lighting element, wherein the shading element comprises an outer side and an inner side. The shading element is formed from interwoven electrically conductive first thread elements and electrically insulating second thread elements. The first and/or second thread elements each may be adapted for reflecting an ambient light. The lighting element(s) may be arranged at the inner side of the shading element and connected with the first thread elements, and the lighting element(s) may be driven by an electrical current, conducted by the first thread elements, resulting in the emission of an artificial light, which may illuminate a plant growing in the greenhouse.

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.
