Beschreibung
Zusammenfassung:	The invention relates to the technical field of manufacturing a composite functional film, and specifically discloses a novel pressure chromogenic flexible film. The novel pressure chromogenic flexible film comprises two layers of ITO films and one layer of a liquid crystal-polymer hybrid material sandwiched between the two layers of ITO films, wherein the liquid crystal-polymer hybrid material comprises 1-82 wt% of a polymer mixture, and 18-99 wt% of liquid crystal. The surface color of the film varies under the pressure, and restores to an initial color after instant electric pulse treatment. The novel pressure chromogenic flexible film is saved in energy, convenient to carry, and easy to install, and is environment-friendly, light and handy, convenient, and colorful. The novel pressure chromogenic flexible film will definitely be an optimum material of a novel writing board and electronic paper.
