Title:
ELECTRICALLY POLARIZED PARTICLE AND PREPARATION METHOD THEREFOR, AND ELECTRICALLY POLARIZED COLOR-CHANGING OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2022/218016
Kind Code:
A1
Abstract:
The present application relates to an electrically polarized particle and a preparation method therefor, and an electrically polarized color-changing optical film, which belong to the technical field of electrically polarized color-changing optical thin-film devices. The present application first discloses an electrically polarized particle, raw materials of which mainly comprise metal iodide, a carboxylic acid nitrogenous organic molecule, elemental iodine, and a cellulose suspending agent. The electrically polarized particle has a rod-shaped structure. The length of the electrically polarized particle is 100 nm to 2000 nm, and the width of the electrically polarized particle is 10 nm to 200 nm. The present application further discloses a preparation method for the electrically polarized particle. The present application also further discloses an electrically polarized color-changing optical film, which contains the electrically polarized particle. In the present application, the prepared electrically polarized color-changing optical film has the effects of a quick response speed, a wide color-changing range, low haze, being easy to process in a large area, and being more suitable for large-scale practical application.
