What is smart glass comprised?
Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
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 is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
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.
Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.
You can find PDLC glass in commercial and residential smart windows, consumer electronics and display cases for retail and museums, as well as in healthcare, hospitality and transportation.
Smart glass/film consumes less than 5W/sqm.
