PDLC film (polymer dispersed liquid crystal film) which is a kind of high-tech
product can switch from transparent to opaque instantaneously under
electricity application. It is transparent when power on and it is
opaque when power off. It can be regulated and adjusted the light
transmittance pass through the film by electricity supply.
Thefilm is composed of PET film,ITO film,polymer and liquid crystal
molecules. When the film is under off state, the randomly aligned
liquid crystal molecules stay along on the walls of capsule, the
reflection of liquid crystal molecules and polymer makes light
disperses then it is opaque. Whileelectricity supplied, these
molecules arrange themselves in a specific direction then parallel
light can pass through the film makes it transparent.
