What is smart glass comprised?
Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
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.
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.
Can smart glass/film be used in wet areas?
Yes, smart glass/film can be used in wet areas such as bathrooms. The edges of smart glass/film are are sealed with a non-acid silicone gel that prevent any contact with water.
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.
