Abstract

The single-layer Ti₃C₂T_x/MXene has become a special electromagnetic wave absorber near the terahertz band because of its abundant surface groups and excellent conductivity. However, the macro-preparation of single-layer Ti₃C₂T_x/MXene shows significantly difficult to influence its application. The two-dimensional Ti₃C₂T_x is easily prepared to have high production, but its weak absorption ability due to high surface conductivity also restricts its application. To realize the strong electromagnetic wave absorption of two-dimensional Ti₃C₂T_x/MXene, a new strategy with magnetic FeNi nanoparticles decorating Ti₃C₂T_x/MXene composites (FeNi-Ti₃C₂T_x) were proposed and the effective electromagnetic wave absorption features covering 170–220 GHz that means the absorption band width reach 50 GHz. With an absorber composite film thickness being only 0.6 mm, the absorptivity of the composite is enhanced with the increase of decorating FeNi nanoparticles and promote up to 75% when the FeNi nanoparticles loading content reaches 30 wt%. The improvement of absorption is attributed to the introduction of soft magnetic FeNi to adjust the high surface conductivity of MXene and improve the electromagnetic balance of the absorber.
