Abstract

The invention discloses a method for preparing a mechanical expansion and discoloration mechanism device, which consists of a hollow tube, a double-layer elastic film, a base color filler and a piston. The double-layer elastic film fixes and covers one end of the hollow tube. The base color filler is filled in the hollow tube, and the piston is arranged at the other end of the hollow tube. The device of the present invention is low in cost, simple in preparation, easy in operation, and controllable. The equipment used in the method is simple, and the light-controlled double-layer elastic The color composition, structure and performance of the film and the base color filler material can be controlled according to the needs. The device has the characteristics of stable structure, fast response, full color spectrum, large size and repeatable color change. The discoloration device is mainly used in the fields of discoloration display, advertisement, military camouflage and decoration.

Description

technical field [0001] The invention relates to the field of color-changing display and camouflage devices, in particular to a method for preparing a fast and simple mechanical expansion and color-changing mechanism device. Background technique [0002] Color-changing materials or technologies have broad application prospects in the fields of display, camouflage and sensing. However, the current research on color-changing materials and devices still has major deficiencies. For example, existing color-changing materials or devices have high material costs, complex devices (such as patent CN103105794B), long response times (such as patent CN109594112A) and can only be used in specific The problem of discoloration between several colors (such as patent CN103757938B), restricts their application. The light-regulating double-layer elastic film proposed by the present invention refers to adjusting the light transmission and reflectivity of the elastic film through mechanical expa...
