Topical: Another use of Vanadium https://www.miragenews.com/mxene-composite-could-eliminate-electromagnetic-877941/
“Because the number of electronics devices will continue to grow, deflecting the electromagnetic waves they produce is really just a short-term solution,” said Yury Gogotsi, PhD, Distinguished University and Bach professor in the College of Engineering, who led the research. “To truly solve this problem, we need to develop materials that will absorb and dissipate the interference. We believe we have found just such a material.”
In the recent edition of Cell Reports Physical Science, Gogotsi’s team reported that combining MXene, a two-dimensional material they discovered more than a decade ago, with a conductive element called vanadium in a polymer solution, produces a coating that can absorb electromagnetic waves.
While researchers have previously demonstrated that MXenes are highly effective at warding off electromagnetic interference by reflecting it, adding vanadium carbide in a polymer matrix enhances two key characteristics of the material that improve its shielding performance.
According to the researchers, adding vanadium to MXene structure — a material known for its durability and corrosion-resistant properties, that is used in steel alloys for space vehicles and nuclear reactors — causes layers of the Mxene to form in sort of electrochemical grid that is perfect for trapping ions. Using microwave-transparent polymer, makes the material also more permeable to the electromagnetic waves.
