Does PDLC smart glass become opaque?
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.
The liquid crystals change their refractive index in relation to the isotropically transparent polymer in which they are immersed, thereby creating multiple step boundaries throughout the PDLC.
It is this change in refractive index at each boundary which causes light to change course. Since the PDLC material contains millions of liquid crystals, each with a boundary facing a slightly different way, the light is scattered in many directions.
The net effect is to hide whatever is behind the PDLC smart glass.
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.
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.
Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
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.
The maximum size of smart glass: 2000mm*6000mm (6.5ft*19.5ft).
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.
