Abstract

A novel flower-like CoLa spheres decorated Ti₃C₂T_x MXene nanocomposite (CoLa/Ti₃C₂T_x) has been prepared by co-solvothermal method. The as-prepared material exhibits excellent electromagnetic wave absorption performance by controlling the mass ratio of Co²⁺ and La³⁺. The minimum reflection loss value (RL_min) of CoLa/Ti₃C₂T_x-17:2 (the mass ratio of Co²⁺ to La³⁺ is 17:2) is − 59.14 dB with the thickness of 1.1 mm at 17.11 GHz. The effective absorption bandwidth (EAB, RL<−10 dB) covers 14–18 GHz (4 GHz in total) under 1.2 mm. The excellent performance of CoLa/Ti₃C₂T_x-17:2 can be attributed to the suitable impedance matching and the synergistic effect of multiple loss mechanism, including interface polarization, dipolar polarization, multiple reflections, natural resonance and exchange resonance. Therefore, the flower-like CoLa/Ti₃C₂T_x nanocomposite is expected to be a promising electromagnetic wave absorption material.
