A liquid crystal is a hybrid between (i) a liquid which flows like a fluid and (ii) a crystal which is normally found as a solid, exhibiting short- or long-range symmetry.
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.
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.
Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.
Yes, smart glass and film can be used in moisture areas so long as the edges are sealed with a non-acid silicone gel. For bathrooms, we recommend using our smart glass product as the switchable PDLC layer is protected from water by the glass. All electrical components need to be sealed and protected from contact with moisture.
Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.
Yes, smart glass can be installed in outdoor areas as normal laminated glass.
