Does PDLC smart glass become opaque?
No, the correct term is translucent, since light still gets through, albeit scattered in many directions. The glass would be opaque only if the light was blocked or absorbed.
The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.

Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.

When not connected to a voltage, typically the transmittance can be as low as 2%. When connected to a voltage, it can be up to 80%, but this maximum value varies from manufacturer to manufacturer.
Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.
Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
