Smart glass
Smart Glass technology comes in 2 main forms; Switchable Smart Glass and Switchable Smart Film, both bringing different advantages and benefits to their customers. In this post, we will be taking a look into the various types of Switchable Smart Glass products, their composition and the special conditions necessary to enable production. In doing this, we will shed light on how the products are made, how they work and how we get them to you.
Switchable Film, (also known as Switchable Smart Film or PDLC Film) is a technology that is capable of adjusting light transmission through the application of an AC power source. The active component in Switchable Film (PDLC - Polymer Dispersed Liquid Crystal) consists of liquid crystal microdroplets which are suspended in polymer. The natural state of the film sees the PDLC molecules arranged in a way that causes light waves to refract through and reflect away from the surface, distorting the state of the glass to present as frosted. When an electrical current is passed through the PDLC layer, the liquid crystal molecules polarise, allowing light to pass through.
