What is a Liquid Crystal?
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.
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.
Which sectors are using PDLC glass?
Transportation
Architectural (residential and commercial)
Interior design
Retail advertising
Healthcare (i.e. hospitals and clinics, since the PDLC smart glass can replace unhygienic curtains and blinds which often carry microbes and germs, and this also improves air quality)
Banking, thanks to the privacy afforded to ATMs and as internal partitions
Hospitality, especially bathrooms, since more natural light can penetrate interior spaces lacking windows to the outside world.
Can smart glass/film be used in bathroom?
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.
What are the major reasons for using PDLC smart glass?
Enhanced security (since the glass is shatter-proof thanks to the internal plastic lamination)
Privacy (thanks to the scattering of light, essentially hiding whatever is behind the smart glass)
Glare reduction (again thanks to the scattering effect)
Reduction of the carbon footprint of the building thanks to the solar control, which reduces HVAC needs, both in summer and in winter
Reduced colour fading of interior furnishings and artworks, thanks to the rejection of UV
Creative marketing, since when the PDLC smart glass is off, the scattering effect creates a screen upon which you can project images.
