Materials development study demonstrates tunable electromagnetic wave absorption and shielding in MXene/metal oxide composites, indicating potential for multiband radar attenuation coatings.
Due to the recent development of detection technology, there is an increasing demand for coating technology that has electromagnetic (EM) wave absorption/reflection characteristics for multi-band including S-band in addition to the existing X-band single wavelength absorption characteristics. In this work, a promising electromagnetic wave absorption and shielding material, MXene/metal oxide composite, was successfully designed and developed. The excellent electromagnetic wave absorption and shielding performance of the composite materials contribute to the synergistic effect of the MXene and the metal oxide, whereby the dielectric properties and electromagnetic wave loss can be easily controlled to obtain appropriate impedance matching conditions and excellent electromagnetic wave dissipation ability.
