Inexpensive Electromagnetic Interference Shielding Now a Reality with MXene

Drexel’s MXene Helps Contain ‘Electromagnetic Pollution’


Electromagnetic interference is perceived to be an increasing problem as electronic devices including cell phones proliferate, especially in automobiles and most especially in electric vehicles. Although interference from electromagnetic radiation is not new, the large number of devices in modern usage has contributed to a steep curve in radiation causing problems to adjacent technologies and potential human health issues.

The effective blocking of, or shielding against, electromagnetic waves is a goal of researchers, which appears to have been achieved with an inexpensive material called MXene, which comprises a class of two-dimensional inorganic compounds constructed from titanium and carbon. The material works by absorbing and trapping the electromagnetic radiation between its layers.

A team from the Korea Institute of Science and Technology (KIST) led by scientist Gu Jong-min and a research team of Drexel University is developing the material funded by the country’s Ministry of Science.
