A Sandia National Laboratories team developed a molecule that enhances materials’ durability by modifying their temperature responsiveness. This innovation, with wide-ranging applications from electronics to defense, is being refined for commercial production.A research team at Sandia National Laboratories has developed a molecule that helps change the way some materials react to temperature fluctuations, enhancing their durability.
“Take for example, your phone, which has a plastic housing, coupled to a glass screen, and inside that, the metals and ceramics that make up the circuitry,” Redline said. “These materials are all screwed, glued or somehow bonded together and will start expanding and contracting at different rates, putting stresses on one another which can cause them to crack or warp over time.
“This really is a unique molecule that when you heat it up, instead of it expanding, it actually contracts by undergoing a change in its shape,” Redline said. Another key to this invention is that it can be incorporated into different parts of a polymer at different percentages, in 3D printing.
