What is PDLC?
Polymer-dispersed liquid crystal (PDLC) film a smart window film that consists of a thin PDLC layer (10~30 ㎛) sandwiched between two transparent conductive substrates. PDLC is a composite of randomly distributed microdroplets of liquid crystalline materials in a polymer matrix, formed by the phase separation of liquid crystal (LC) and polymer from a homogeneous single-phase mixture. The LC domains can provide electro-optically controllable functions because of their orientation being influenced by an applied electrical field, whereas the polymer matrix provides mechanical, thermal, and environmental stability. In the off-state, a PDLC composite appears opaque because it strongly scatters light because of the refractive index mismatch between the LC droplets and the polymer matrix, whereas in the on-state a PDLC becomes transparent because it allows light to pass because of the reorientation of LC within the droplets and matching of the refractive indices of LC and polymer.
Applications of PDLC
The intrinsic ability of PDLC to modulate light (scattering mode) means that it has potential applications in various electro-optical devices, such as switchable privacy windows (smart windows), optical shutters, tunable LC lenses, flexible displays, electric curtain, projection screens, and other light-control devices in architectural, automotive and consumer electronic industries.
