MIT develops stained glass in very fast time, without maintaining power

Just a button, the entire window on the car or window, . will quickly convert from transparent to completely black glass, thereby preventing sunlight from entering to warm up the space inside. without having to use light screens or pulling the film as in the past . That is the ability of the stained glass system that researchers at MIT have successfully developed.

Their way is to use electrochromic materials with the ability to change colors immediately from four transparent to black like by passing electricity. Of course, this is a method that has been applied for a long time by car companies or glass companies. However, this MIT system allows for a faster color change and requires less energy.

It is known that previous systems that took several minutes to change the color of the material and that the system could not reach the desired black color. Furthermore, these methods need to have electric current flowing continuously to keep the door opaque. Now with the new technology, MIT's window will turn into black with just one button, keeping the chromaticity almost completely black without continuously powering the system.

This MIT system allows for faster color change and requires less energy.

In an experiment to verify the response time of the stained glass system, the team used a sponge-like material called an organic metal frame with rapid conductivity and ions. When an electric current is applied, the window will be negatively charged and positive ions will continuously "attack" in order to neutralize electricity, thereby causing a color-changing effect. On the other hand, they also mixed two types of dye chemicals for windows into red and blue to create an almost black color.

Mircea Dincă, a chemistry professor at MIT, who led the project, said the technique could lead to "a step toward energy savings" because it helps reduce the cost of air conditioning. "You just need to turn on the switch when the sun shines through the window and turns it black," he said. He even believes that this technology will pave the way for the introduction of low-power smart displays similar to e-ink screens on Kindles. Now, despite demonstrating the effectiveness of this method in the laboratory, researchers must continue to show its feasibility on an industrial scale before life can be widely applied. .
