Smectic phase liquid crystal dimming sheet and manufacturing method thereof

Abstract

The invention discloses a smectic phase liquid crystal dimming sheet and a manufacturing method thereof. The dimming sheet comprises two body layers; a smectic phase liquid crystal dimming film layer is arranged between the two body layers; the smectic phase liquid crystal dimming film layer comprises two conductive electrode layers; a mixing layer is arranged between the two conductive electrode layers; the inner side face of each body layer is adhered to the outer side face of the corresponding conductive electrode layer through an adhesive layer; and a matrix layer can be arranged between each conductive electrode layer and the adhesive layer. The manufacturing method comprises the following steps of: cleaning and drying the matrix layer; manufacturing the conductive electrode layers; manufacturing the mixing layer; laying the adhesive layer and the body layers to obtain an initial laminated structure of the dimming sheet; and pressurizing, heating and cooling to obtain the dimming sheet. The dimming sheet provided by the invention has the characteristics of multiple steady states, is green, has low carbon, is healthy and environment-friendly, and can be widely applied to fields, such as architectural ornament and decoration, privacy control area and automotive electronics. The manufacturing method provided by the invention is simple and easy to control, has very low cost and is suitable for industrialization.

Description

technical field [0001] The invention relates to a dimming structure and a manufacturing method thereof, in particular to a polymer structure-encapsulated smectic phase liquid crystal dimming sheet and a manufacturing method thereof. Background technique [0002] At present, the dimming glass market is booming, and there are more and more types of dimming glass, which are widely used in automotive glass, architectural decoration, outdoor curtain walls and other fields. Dimming glass is a kind of electrochromic dimming glass, which controls the state of functional materials in polyester film or interlayer through safe low voltage, so as to achieve the purpose of dimming. The color depth of this electrochromic tinted glass can be controlled by changing the electric current, thereby adjusting the intensity of sunlight entering the room. When a voltage is applied to the electrochromic dimming glass, the electrochromic material in it is colored, and when the voltage is removed, t...

Problems solved by technology

However, this liquid crystal polymer dimming technology only has two states of transparent and opaque, and it is not "multi-stable". Like traditional nematic liquid crystals, it needs continuous power supply to maintain a transparent state.
