Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
Share with you all about smart glass.
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.
Are PDLCs only available as artificial materials?
Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
What is the power consumption of smart glass/film?
Smart glass/film consumes less than 5W/sqm.
Can smart glass/film be regulated to gradually change its state?
Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.
Where can we find PDLC smart glass?
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.
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.
