Abstract

The invention discloses a rapid and simple preparation method of a mechanical expansion discoloration mechanism device. The device consists of a hollow pipe, a double-layer elastic film, a ground color filler and a piston; the double-layer elastic film fixedly wraps one end of the hollow pipe; the hollow pipe is filled with the ground color filler, and the piston is arranged at the other end of the hollow pipe. The device disclosed by the invention is low in cost, simple to prepare, easy to operate and controllable; equipment used in the method is simple, and the color composition, the structure and the performance of the light-operated double-layer elastic film and the ground color filler material can be controlled as required. The device has the characteristics of stable structure, quickresponse, full chromatography, large size, repeatable discoloration and the like. The color changing device is mainly used in the fields of color changing display, advertisements, military camouflage, decoration and the like.

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, military 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 mechan...
