MXene: A Rising Star 2D Material

With the rapid development of “smart homes,” “smart cities” and “smart shopping,” the Internet of Things (IoT) has grown to be an inevitable part of people's lives, resulting in a massive increase in electronic and telecommunication devices.

An electromagnetic interface (EMI) is generated by the magnetic and electrical waves of different devices interfering with one another, which may have pernicious effects on the performance of extremely sensitive precision electronic equipment as well as on human health. Thus, the necessity and urgency of developing novel materials to preclude or repress EMI have arisen.

Metals are known to be effective traditional materials, reflecting the major portion of electromagnetic wave along with minor absorption. Intrinsic conductive polymers, carbon-based materials such as carbon black, carbon fibers, carbon nanotubes, and graphene have been widely used in EMI shielding due to their high mechanical strength, electrical conductivity, corrosion resistance, and lightweight properties.

MXene group materials, known as the rising star of 2D materials, are promising materials in EMI shielding. MXenes were introduced by Drexel University scientists in 2011 with the general formula M(n+ 1)XnTx. M(n+1)AXn (MAX) is a class of 2D transition metal carbides, nitrides and carbonitrides synthesized from precursor materials, where M represents a transition metal (Sc, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, etc.) and A represents Al, Si, Ga, etc. X is C and/or N and n = 1-4. Tx can typically be surface functional groups such as -O, -OH, -F and/or -Cl.

Ti3C2Tx, the most widely studied member of the MXene family, has a wide range of application potential, from wastewater treatment to anti-corrosion coatings, from wearable devices to smart energy systems. This material also has excellent EMI shielding properties. Due to these properties, MXene group materials attracted the attention of SUNUM researchers and Ti3C2Tx is currently being produced at SUNUM. It is aimed to use MXene to develop multifunctional composites for EMI shielding, fire retardancy, and biomedical applications. Ti3C2Tx produced at SUNUM is available to national and international researchers on SUNUM's online sales platform e-Store.
