Description

technical field [0001] The invention relates to a dimming film and a preparation method thereof, in particular to a dimming film made of a transparent conductive film and a preparation method thereof. Background technique [0002] Dimming film (PDLC Film) is an electronic light control product, which refers to the solidification of polymer dispersed liquid crystal between two transparent conductive films. In the absence of an electric field, the dimming film is in an opaque state. When AC power is applied, it is in a transparent state. Generally used for glass partitions, such as hotel partitions, office partitions, bathroom partitions, bank, ticket office window partitions, etc., beautiful and can protect privacy, with multiple functions such as waterproof, heat insulation, dimming, etc., also used in villa windows Glass, car window glass, wine cabinet, bookcase, vending cabinet and other door glass can control the light and privacy; it can also replace the projection scre...
