Abstract

The invention provides a color-changing device and a preparation method thereof. The color-changing device comprises at least one color-changing unit, and the color-changing unit comprises a first electrode, a second electrode and a color-changing structure located between the first electrode and the second electrode; the color changing structure is configured to reflect light with a specific color wavelength in response to the action of external light under the condition that a voltage difference is not applied to the first electrode and the second electrode; and when a voltage difference is applied to the first electrode and the second electrode, the first electrode and the second electrode deform to reflect light of other color wavelengths in response to the action of external light.

Description

technical field [0001] The present disclosure relates to the field of color-changing devices, in particular to a color-changing device and a preparation method thereof. Background technique [0002] Chameleons can change their color to camouflage themselves, communicate and regulate temperature. At present, materials and devices with color-changing characteristics are usually used in the fields of stealth technology, anti-counterfeiting measures, and electronic displays. However, existing color-changing materials and devices have limitations, and usually require mechanical devices to apply external force to stretch to achieve color change, which cannot be realized. Free adjustment of discoloration, unable to scale production. Contents of the invention [0003] Embodiments of the present disclosure provide a color-changing device and a preparation method thereof. [0004] According to the first aspect of the present disclosure, the present disclosure provides a color-chan...
