MXene, the new family of two-dimensional materials having numerous nanoscale layers, is being considered as a novel microwave absorption material. However, MXene/functionalized MXene-loaded polymer nanocomposites exhibit narrow reflection loss (RL) bandwidth (RL less than or equal to −10 dB). In order to enhance the microwave absorption bandwidth of MXene hybrid-matrix materials, for the first time, macroscopic design approach is carried out for TiO₂-Ti₃C₂T_x MXene and Fe₃O₄@TiO₂-Ti₃C₂T_x MXene hybrids through simulation. The simulated results indicate that use of pyramidal meta structure of MXene can significantly tune the RL bandwidth. For optimized MXene hybrid-matrix materials pyramid pattern, the bandwidth enhances to 3–18 GHz. Experimental RL value well matched with the simulated RL. On the other hand, the optimized Fe₃O₄@TiO₂-Ti₃C₂T_x hybrid exhibits two specific absorption bandwidths (minimum RL value - −47 dB). Compared with other two-dimensional nanocomposites such as graphene or Fe₃O₄-graphene, MXene hybrid-matrix materials show better microwave absorption bandwidth in macroscopic pattern.

MXene是具有许多纳米级层的新型二维材料家族，被认为是一种新型的微波吸收材料。但是，MXene /官能化的MXene负载的聚合物纳米复合材料表现出较窄的反射损耗（RL）带宽（RL小于或等于-10 dB）。为了提高MXene杂化材料的微波吸收带宽，首次对TiO ₂ -Ti ₃ C ₂ T _x MXene和Fe ₃ O ₄ @TiO ₂ -Ti ₃ C ₂进行了宏观设计。Ť _XMXene通过仿真进行混合。仿真结果表明，使用MXene的金字塔元结构可以显着调整RL带宽。对于优化的MXene混合矩阵材料金字塔图案，带宽可提高到3–18 GHz。实验RL值与模拟RL很好地匹配。另一方面，优化的Fe ₃ O ₄ @TiO ₂ -Ti ₃ C ₂ T _x杂化物表现出两个特定的吸收带宽（最小RL值--47 dB）。与其他二维纳米复合材料（例如石墨烯或Fe ₃ O ₄石墨烯）相比，MXene杂化基质材料在宏观模式下显示出更好的微波吸收带宽。
