Example Embodiment

[0030] Example 1:

[0031] In a three-neck flask equipped with a condenser and a thermometer, add 20g of butyl methacrylate prepolymer, 77g of acetylene bridged liquid crystal and 3g of 1-hydroxycyclohexane phenyl ketone, and stir at 80°C for 30 minutes to make the solution clarify.

[0032] Pour the above-mentioned clear solution into the coating roller, and coat it on the surface of a 10cm×10cm polyester conductive film (20Ω / □). Control the speed of the roller to make the thickness of the solution layer 10μm, and then paste another layer through the roller. For the polyester conductive film of the same size, lead wires through the conductive graphite glue on the two polyester conductive film layers for use, and cure for 2s under UV light 365nm to obtain a flexible electrochromic film.

Example Embodiment

[0033] Example 2:

[0034] In a three-necked flask equipped with a condenser and a thermometer, add 40g of butyl methacrylate prepolymer, 58g of acetylene bridged liquid crystal and 2g of 1-hydroxycyclohexane phenyl ketone, and stir at 80°C for 1 hour to make the solution clarify.

[0035] Pour the above clear solution into a roller, and coat it on the surface of a PI conductive film (100Ω / □) with a size of 20cm×20cm. Control the speed of the roller to make the thickness of the solution layer 50μm, and then paste another layer of the same size on the roller. PI conductive film, lead wires through two layers of PI conductive film layer through conductive gold glue for standby, curing under UV light 365nm for 3s, then flexible electrochromic film is obtained.

Example Embodiment

[0036] Example 3:

[0037] In a three-necked flask equipped with a condenser and a thermometer, add 8g of butyl methacrylate prepolymer, 90g of acetylene bridged liquid crystal and 2g of 1-hydroxycyclohexane phenyl ketone, and heat at 80°C under magnetic stirring. 1.5h to make the solution clear.

[0038] Pour the above-mentioned clear solution into a roller, coat it on the surface of a 50cm×50cm polyester conductive film (80Ω / □), control the speed of the roller to make the thickness of the solution layer 40μm, and then paste another layer of the same size through the roller Use conductive silver glue to draw wires from the two polyester conductive film layers for use in the polyester conductive film, and cure for 5 seconds under 365nm ultraviolet light to obtain a flexible electrochromic film.

Abstract

This invention relates to one flexible electrical variable change film process method and the film in the optical materials technique, which comprises the following steps: adopting roller coating method for one layer of the allyl propionate pre-polymer part on film surface and mixture solution to row phase liquid crystal and light triggered agent; then through roller adding other layer of conductive electrical film through ultraviolet light fixing to form flexible polymer disperse LCD film.

Description

technical field [0001] The invention belongs to the technical field of optical materials, and in particular relates to a method for preparing a flexible electrochromic film and a flexible electrochromic film prepared by the method. technical background [0002] Polymer-dispersed liquid crystal (polymer-dispersed liquid crystal, PDLC) film is a film formed by uniformly dispersing tiny nematic liquid crystal droplets in a polymer matrix. Generally, the polymer prepolymer, liquid crystal molecules and photoinitiator are injected into the liquid crystal cell formed by two pieces of conductive glass, and the polymer dispersed liquid crystal film is formed after photocuring. Usually, the film thickness obtained by controlling the distance between two conductive glasses is tens of microns, and the liquid crystal droplet size is about several microns. The orientation of the liquid crystal molecules in each droplet is distributed along the bipolar axis, and the refractive index alon...
