Smart Glass Film technology reaches the automotive market, promising to revolutionize not only the film sector, but also open up new possibilities in energy efficiency and light control.

If you still think that the glass film It's just that adhesive layer that gives you a little privacy in the car, get ready to have your mind blown.

We are talking here about a true technological advance: the smart glass film, which works through a technology known as electrochromic.

In a recent demonstration video, you can see how this innovative material changes its transparency according to the applied electrical voltage. So, let's break down this news, which promises to be the next big thing.

What is Electrochromic?

The “Q” of the question here is the electrochromic material. When an electric current passes through it, the material changes its optical properties — it can go from transparent to opaque in the snap of a finger. Just imagine, you control all of this directly from your smartphone! Check out the news in the video below.

How smart window film works

It's not magic, it's technology! The film is made up of several layers. Typically, they are two layers of glass or plastic with the electrochromic material in between. And to make things even more modern, there are also transparent conductive coatings on the internal surfaces of the glass or plastic.

Opaque vs transparent state

Now, putting all this together and applying an electrical current, this electrochromic material can change state. In the “normal” state, that is, without electrical current, the material scatters the light, making the glass opaque — ideal for those moments when you want a little more privacy. But with the electrical current activated, it becomes clear as water, allowing light to pass through.

Where is this technology being applied

From homes to commercial buildings, this smart glass film It can help control internal temperature, thereby reducing energy consumption. We are also talking about applications in secure areas, such as banks and government buildings, and even in luxury cars.
