摘　　要：采用水热法制备了MoS2@CoFe2O4复合材料,探究了CoFe2O4添加量对复合材料吸波性能的影响,并通过矢量网络分析仪测试了该复合材料在2~18 GHz频率下的电磁参数,模拟分析了该复合材料的吸波性能。结果表明,当CoFe2O4添加量为0.4 g时,所制得的复合材料吸波性能最佳,最大吸收位于11 GHz,为-59.9 dB,相应的匹配厚度为2.7 mm,并且当匹配厚度为2 mm时,其有效吸收频带宽度(-10 dB以下)为4.63 GHz(12.58~17.21 GHz)。表明MoS2@CoFe2O4复合材料在微波吸收方面具有潜在的应用价值。MoS2@CoFe2O4 composites were prepared by hydrothermal method.The influence of CoFe2O4 addition amount on the absorption performance of the composites was explored.The electromagnetic parameters of the composites in the range of 2 GHz to 18 GHz were measured by vector network analyzer.The microwave absorbing properties of the composites were simulated and analyzed.The results show that when the addition amount of CoFe2O4 is 0.4 g,the MoS2@CoFe2O4 composites have the best wave absorption performance.When the matching thickness is 2.7 mm,the maximum reflection loss can reach-59.9 dB at 11 GHz.When the matching thickness is 2 mm,the effective absorption band width(below-10 dB)is 4.63 GHz(12.58~17.21 GHz).It shows that MoS2@CoFe2O4 composites have potential application value in microwave absorption.
