As the world continues to look for sustainable conductor materials, scientists at the University of Chicago have discovered a way to create a material that’s made like plastic, but conducts electricity as if it were a metal
shows how to make a kind of material in which the molecular fragments are jumbled and disordered, but can still conduct electricity extremely well.
Jiaze Xie , the first author on the paper added, “Essentially, it suggests new possibilities for an extremely important technological group of materials.”Conductive materials are absolutely essential if you’re making any kind of electronic device, whether it be an iPhone, a solar panel, or a television. By far the oldest and largest group of conductors is the metals: copper, gold, aluminum.
Then Xie began experimenting with some materials discovered years ago, but largely ignored. He strung nickel atoms like pearls into a string of molecular beads made of carbon and sulfur, and began testing. Xie, Anderson, and their lab worked with other scientists around the university to try to understand how the material can conduct electricity. After tests, simulations, and theoretical work, they think that the material forms layers, like sheets in a lasagna. Even if the sheets rotate sideways, no longer forming a neat lasagna stack, electrons can still move horizontally or vertically – as long as the pieces touch.
One of the material’s attractive characteristics is new options for processing. For example, metals usually have to be melted in order to be made into the right shape for a chip or device, which limits what you can make with them, since other components of the device have to be able to withstand the heat needed to process these materials.
