Share with you all about smart glass.

Are PDLCs only available as artificial materials?

Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.

How much light does PDLC glass transmit?

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.

>>>

Why does PDLC require a polymer?

The polymer allows the liquid crystals to be embedded into a film, which can then be sandwiched between panels of glass or plastic. The polymer has constant optical properties which do not vary across its structure, and hence is considered isotropic.
In contrast, the liquid crystal itself is anisotropic, since its optical characteristics are not constant across its structure, but rather can vary under application of an electric field.
