Microwave synthesis generates Mxene 25 times faster than traditional methods, using 75% energy

Mxene is a lightweight two-dimensional (2D) material that can protect spacecraft, mechanical components, and even people from harmful radiation. Traditional synthesis requires a multi-step process that can take up to 40 hours, making Mxene difficult to generate.

By introducing a rapid single-step microwave synthesis method, researcher Reeja Jayan reduced production time for Mxene to 90 minutes, reducing energy consumption by 75%.

“These are the best ways to get to know the best,” said Jayan, a professor of mechanical engineering at Carnegie Mellon University.

This study, published in Materials Science in Semiconductor Processing, also demonstrates its unique ability to customize the composition of Mxene and change the type of radiation the material can protect. Until now, teams have tested materials across the X-band (X-band in the 8.0-12.0 GHz range), but protecting space electronic materials requires more testing against space radiation.

“We assumed we would lose some of our shield performance in return because we made the process more exciting,” Jayan said. “There were subtle structural differences, but I was surprised that we didn’t see any trade-offs in shielding efficiency at a lab scale.”

As we move forward, Jayan tests the synthesis process on a large scale. Working with the aerospace materials manufacturer, her team will integrate Mxene into the test panel for radiation testing.

“We have developed a low-carbon process that saves a lot of energy. If this can be expanded more than ever, then more than ever, we will create a much more necessary and substantial environmental impact.”
