摘　　要：选择Ti_(3)AlC_(2)作为典型的MXene前驱体,采用氟化物/盐酸刻蚀法去除Al层,成功制备了Ti_(3)C_(2)T_(x) MXene纳米吸波材料。详细分析了所得Ti_(3)C_(2)T_(x) MXene的微观结构和化学组成,结果表明Ti_(3)C_(2)T_(x) MXene具有较大的薄片尺寸和较少的缺陷。电磁参数的测试结果表明,经刻蚀法制备的MXene显示出优越的电磁波吸收性能,尤其在高频段(8.2~12.4 GHz)具有显著的吸收能力。Ti_(3)AlC_(2) was selected as a typical MXene precursor,and the Ti_(3)C_(2)T_(x) MXene nano absorbing material was successfully prepared by removing the Al layer using fluoride/hydrochloric acid etching method.The microstructure and chemical composition of the obtained Ti_(3)C_(2)T_(x) MXene were analyzed in detail,and the results showed that Ti_(3)C_(2)T_(x) MXene had a larger sheet size and fewer defects.The test results of electromagnetic parameters showed that the MXene prepared by the etching method exhibited superior electromagnetic wave absorption performance,particularly in the high frequency range(8.2~12.4 GHz)with significant absorption capability.
