Can smart glass be used in outdoor applications?
Yes, smart glass can be installed in outdoor areas as normal laminated glass.
Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.

PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.
Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.
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.

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.
