MXenes are a lightweight two-dimensional, or 2D, material capable of protecting everything from spacecrafts, mechanical components, and maybe even people, from harmful radiation. Because traditional synthesis requires multi-step processes that can take up to 40 hours, MXene is difficult to produce.
By introducing a rapid single-step microwave synthesis method, Reeja Jayan has reduced MXene production time to ninety minutes and cut energy consumption by 75%.
The research, published in Materials Science in Semiconductor Processing, also demonstrates a unique ability to customize MXene’s composition to change the type of radiation that the material can protect against. To date, the team has tested their material across the X-band–radio frequencies ranging from 8.0-12.0 GHZ–but to protect against electronic materials in outer space, more testing against cosmic radiation is needed.
“We assumed that, because we sped up the process, we would lose some of the shielding performance in return,” said Jayan. “We were pleasantly surprised that, although there are subtle structural differences, we didn’t see any shielding efficiency tradeoff at the lab scale.”
Moving forward, Jayan will test her synthesis process at a larger scale. In partnership with an aerospace materials manufacturer, her team will integrate MXene into test panels for radiation testing.
“We’ve developed a low carbon process that significantly saves energy. If it can be scaled up now, more than ever before, we stand to create a critically needed and substantial environmental impact.” Reference Energy-efficient synthesis of Ti3C2Tx MXene for electromagnetic shielding
