Scientists have developed a way to stretch and stretch liquid crystals to produce different colors. Can be used in
color changer is known for its ability to change color. Inspired by this, scientists at the University of Chicago's Pritzker School of Molecular Engineering (PME) developed a way to stretch and stretch liquid crystals to produce different colors
. By creating polymer films filled with liquid crystal droplets and then processing them, they determined the basis for color-changing sensing systems that can be used in smart coatings, sensors and even wearable electronic devices. The study was led by Juan de Pablo, a family professor of molecular engineering at Liew.
liquid crystals with different molecular orientations have become the basis of many display technologies. But de Pablo and his team are interested in character-coded liquid crystals, which have twists and turns and some asymmetrical "inertia", such as right or left inertia, which makes them more interesting optical behaviors.
"Possibilities are really open to imagination
these crystals can also form so-called "blue-phase crystals" that have liquid and crystal properties and, in some cases, can reflect or reflect visible light, rather than the liquid crystal itself. If stretched or stretched, they produce a variety of optical effects, but they also know that it is not possible to directly stretch or stretch the liquid, but instead place tiny droplets of liquid crystal in a polymer film.
way, we can encapsulate hand LCDs and deform them in a very specific, highly controlled way," said Pablo, a technology minister. This enables you to understand the characteristics of them and the behavior they exhibit. By doing so, the researchers found more different phases (the molecular configuration of crystals) than previously known. These stages produce different colors depending on how they are stretched or stretched, even as the temperature changes.
, "Now, the possibilities really open up the imagination," pablo said. Imagine using these crystals in textiles to change color depending on temperature, or when bending elbows. More
