“…Electromagnetic (EM) waves have always been the key character in the development of wireless communication and electronics applications but cause serious issues such as the threat to the health of the public, the interference to the instrument preciseness, and the risk to information leakage. − Ferromagnetic metal powders were often used as microwave absorption (MA) materials to address the above issues. , However, in the era of five generation (5G) communication, novel MA materials with lower density and easy fabrication processes are still in urgent demand.…”

Ti3C2T x has microwave absorption (MA) properties due to its dielectric loss, but the absence of magnetic loss capability of pure Ti3C2T x causes unmatched impedance and unsatisfied MA performance. Modification of Ti3C2T x with magnetic particles is an effective way to introduce the magnetic loss mechanism. However, these modified Ti3C2T x particles have higher density and require complicated fabrication processes, restricting the industrial production and functional applications. Here, a low-temperature and simple method of radio-frequency N2 plasma treatment was adopted to modify Ti3C2T x with N. More interestingly, the N-doped Ti3C2T x flakes demonstrated magnetic properties and thus exhibited drastically enhanced MA properties. The minimum reflection loss (RLmin) of −59.20 dB at 10.56 GHz was achieved in N-doped Ti3C2T x products after only 3 min of plasma treatment, remarkably higher than RLmin of −11.07 dB at 7.92 GHz for the pristine Ti3C2T x . The main mechanism is due to the combination of dielectric loss, magnetic loss, and the good impedance matching in the N-doped Ti3C2T x . Further prolonging the nitriding time induces much desorption of −F and the formation of TiO2, thus deteriorating the impedance matching and the MA properties.
