摘要：

The neodymium oxide carbonate (Nd2O2CO3) was prepared from neodymium hydroxide (Nd(OH)(3)) by hydrothermal and 550 degrees C heat treatment. Then, the MoS2/Nd2O2CO3 composites with different contents of Nd2O2CO3 were synthesized and the microwave absorption properties of MoS2/Nd2O2CO3 were studied. The results show that the MoS2/Nd2O2CO3 composites achieved stronger electromagnetic wave absorption performance than pure MoS2. The lamellar structure of NdO2CO3 provided attachment points for MoS2 and then formed MoS2/Nd2O2CO3 composites with multilayer flower-like structures according to the principle of directional aggregation. The multiple interface polarization between MoS2 and Nd2O2CO3 is good for electromagnetic absorption. And, the absorbing performance of MoS2/Nd2O2CO3 is also affected by the content of Nd2O2CO3. The minimum reflection loss (RL) peak of MoS2/Nd2O2CO3 with 0.03 g Nd2O2CO3 reached -54.2 dB at 12.3 GHz with a calculated thickness of 2.5 mm.
