Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
With no applied voltage, the liquid crystals are randomly oriented and scatter the light which enters. When an electrical signal is applied, the liquid crystals orient themselves parallel to each other, allowing light through.
Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.
No, the transmittance (level of transparency) of the PDLC can be varied from 0% in the OFF state up to any value you want until you reach the maximum transmittance (normally 70% or 80%). This is done by simply altering the voltage from 0 VAC up to 70VAC, which is typically the maximum recommended voltage. This can be done electrically with a variable isolating transformer, or electronically with a switched-mode smart glass dimmer.
Yes, smart glass can be installed in outdoor areas as normal laminated glass.
