Abstract

The great potential for electromagnetic wave (EMW) absorption is revealed in two-dimensional (2D) Ti3C2Tx (MXene) thin sheets that have numerous surface flaws and an extensive spectrum of functional groups. In this study, Ti3AlC2 (MAX Phase) is etched, and then ultrasonic exfoliation is used to create 2D ultrathin Ti3C2Tx nanosheets; a type of MXene. The MnCo2O4 spherical particles were grown on the layered structure of Ti3C2Tx via a one-pot hydrothermal process. The synthesized Ti3C2Tx/MnCo2O4 composite provides superior bulk-to-surface and interfacial charge transfer capabilities due to their short charge transfer distance and extensive interface contact area to the EMW. This article thoroughly evaluates the loss impact in Ti3C2Tx/MnCo2O4 absorbers as -44.4dB of reflection loss at 16.04GHz with a thickness of 5.114mm for the first time, which is essential for fabricating an effective microwave absorber.
