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.
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.
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 is a safety glass. Being laminated, it prevents scattering of glass fragments in case of breakage.
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.
Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.
Yes, smart glass/film is a safety glass. Being laminated, it prevents scattering of glass fragments in case of breakage.
