In this work, 2D-layered Ti3C2/TiO2 hybrids derived from Ti3C2 MXenes were calcined at different temperature for 2 h with a ramping rate of 5 °C/min to adjust the electromagnetic wave absorption performance, and the static dielectric properties of the Ti3C2 and anatase TiO2 were studied by density functional theory calculations to illustrate the contribution to dielectric loss of TiO2 and Ti3C2 MXenes. The 2D-layered Ti3C2/TiO2 Hybrids exhibit a minimum reflection loss of −40.07 dB at 19.2 GHz with a relative thin thickness of 1.1 mm, and the effective bandwidth with reflection loss less than −10 dB reaches more than 3.6 GHz. The calculated results display higher ε' and ε'' of Ti3C2 MXenes than that of anatase TiO2 in the measured range of frequency, which is in accordance with the experiments. The 2D-layered Ti3C2/TiO2 hybrids are expected to exhibit the enhanced electromagnetic wave absorption performance thanks to the appropriate complex permittivity, matching impendence and high dielectric loss.
