Problems solved by technology

However, because the dielectric becomes a conductor under high-frequency voltage, this mode consumes a lot of power and is difficult to drive. It only stays in small-sized samples and has no practical products. Some other ideas of trans-type electronically controlled dimming glass cannot be realized due to various reasons. industrialization

Embodiment 1

[0039] Example 1, the polymer-dispersed negative liquid crystal trans-type electronically controlled dimming glass is manufactured in a clean workshop, and the steps of the preparation method are:

[0040] The first step is to prepare the prepolymer

[0041] With 20% alkoxynonyl acrylate, 70% trimethylolpropane triacrylate, 2% toughening agent nitrile rubber, 3% chain transfer agent 2-mercaptoethanol and 5% light Initiator 1173 prepares the prepolymer, stirs the mixture at room temperature for 2 minutes and mixes well, the refractive index of the prepolymer after curing is n p = 1.517.

[0042] The second step is to prepare liquid crystal glue

[0043] Mix the prepolymer configured in the first step with the nematic negative liquid crystal material (negative liquid crystal HNG720200-100 provided by Jiangsu Hecheng Display Technology Co., Ltd.) in a mass ratio of 1:1, and stir with a stirrer at room temperature Make it fully mixed for 2 minutes to form a liquid crystal glue,...

Abstract

The invention relates to trans-electric-control dimming glass of polymer scattering negativity liquid crystal manufactured on the basis of strain liquid crystal theory. The trans-electric-control dimming glass is composed of two float-glass-process ultra-flat transparent conductive thick-glass interlayer polymer scattering negativity liquid crystal films. Prepolymers of polymer scattering negativity liquid crystal are composed of polymerizable monomers added with photoinitiator, chain transfer agent, flexibilizer and the like. Ultraviolet curing prepolymer and nematic phase liquid crystal are mixed to form liquid crystal glue. During preparation, tensile stress is applied to enable polymer perpendicular surfaces to be stereospecifically polymerized, and negativity liquid crystal molecules are arranged on the perpendicular surfaces. The trans-electric-control dimming glass of polymer scattering negativity liquid crystal has transparent appearance, when voltage is applied, liquid crystal molecules are disorderly arranged in two dimensions along the perpendicular surfaces, and the trans-electric-control dimming glass is turned into scattering state. The trans-electric-control dimming glass of polymer scattering negativity liquid crystal can manufacture products with large area and is applicable to the fields of indoor decoration and the like.

Description

technical field [0001] The technical solution of the invention relates to a polymer-dispersed negative liquid crystal trans-type electronically controlled dimming glass manufactured by strained liquid crystal technology. Background technique [0002] Polymer dispersed liquid crystal (PDLC) technology has been widely used in electronically controlled dimming glass, holographic grating and many other technical fields. In the study of polymer-dispersed liquid crystals, it was found that the application of stress has an effect on the polymerization of polymers and the alignment of liquid crystal molecules, that is, the stress-induced liquid crystal orientation. This research field is called strained liquid crystals (SLC). [0003] The product of polymer dispersed liquid crystal has the appearance of foggy frosted glass, and it becomes transparent when an electric field is applied. This is called polymer dispersed liquid crystal formal electronically controlled dimming glass. In...
