摘　　要：采用高温固相法制备TaS_(2)/BDC复合材料,探讨葡萄糖衍生炭掺杂对材料结构及电磁波吸收性能的影响。微观结构表征结果表明,复合材料表面较粗糙,相比纯TaS_(2),片层堆叠现象得到显著改善,葡萄糖衍生炭的引入有效地改善了TaS_(2)纳米片的分散性。XRD结果证实TaS_(2)成功合成,并检测到部分氧化的Ta_(2)O_(5)。XPS分析进一步验证TaS_(2)和葡萄糖衍生炭的存在。电磁波吸收性能测试表明,掺杂质量分数为25%葡萄糖衍生炭显著提高TaS_(2)/BDC复合材料的吸波性能,最大反射损耗达到-45.1dB,吸收频段向高频偏移,吸收率超过99.99%。过量的碳掺杂破坏材料的阻抗匹配,导致吸波性能下降。TaS_(2)/BDC composites were prepared by the high-temperature solid-state method,and the influence of glucose-derived carbon doping on the material structure and electromagnetic wave absorption performance was investigated.Microscopic structural characterization revealed that the composite materials had a rougher surface compared to pure TaS_(2),with a significant improvement in the stacking phenomenon of the layers.The introduction of glucose-derived carbon effectively improved the dispersion of TaS_(2)nanosheets.XRD results confirmed the successful synthesis of TaS_(2)and detected partial oxidation to Ta_(2)O_(5).XPS analysis further verified the presence of TaS_(2)and glucose-derived carbon.Electromagnetic wave absorption performance testing showed that doped with a mass fraction of 25%glucose-derived carbon significantly enhanced the wave absorption performance of TaS_(2)/BDC,with a maximum reflection loss of-45.1 dB,a shift in the absorption frequency range to higher frequencies,and an absorption rate exceeding 99.99%.Excessive carbon doping,however,can disrupt the material's impedance matching,leading to a decrease in absorption performance.
