What is smart glass comprised?
Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.

Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.
Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.
The liquid crystals change their refractive index in relation to the isotropically transparent polymer in which they are immersed, thereby creating multiple step boundaries throughout the PDLC.
It is this change in refractive index at each boundary which causes light to change course. Since the PDLC material contains millions of liquid crystals, each with a boundary facing a slightly different way, the light is scattered in many directions.
The net effect is to hide whatever is behind the PDLC smart glass.
No, the internal PDLC layer is plastic and does not conduct electricity, since it is electrically insulated. Rather, it behaves more like a capacitor, where the applied signal alternates between positive and negative voltages at the plates of the capacitor, causing an alternating electric field throughout the PDLC dielectric, which is what aligns the liquid crystals with the frequency of the signal (normally 50 Hz or 60 Hz).
