中文摘要:
      本文通过球磨法将MWCNTs和TiO2进行混合得出复合粉体,并用XRD、SEM、网络矢量分析仪对复合粉体进行表征,利用数值模型进行理论计算分析其空间吸波特性。研究结果表明加入无水乙醇湿混合的MWCNTs/TiO2复合粉体中的MWCNTs分散性较好;湿混合的MWCNTs/TiO2复合粉体在2~18GHz频段的波阻抗匹配特性和空间吸波能力更佳,为复合吸波材料的实际应用提供了理论参考。

英文摘要:
      In this paper, Multi-walled carbon nanotubes (MWCNTs) and TiO2 were mixed by ball milling to obtain composite powders. The composite powders were characterized by XRD, SEM and network vector analyzer. The absorbing properties of composite powders in space were analyzed by theoretical calculation using numerical model. The results show that the dispersibility of MWCNTs in the MWCNTs/TiO2 compositepowders with anhydrous ethanol wet mixing is better. Wet-mixed MWCNTs/ TiO2 composite powders have better impedance matching characteristics and spatial absorbing ability in 2~18GHz band, which provides theoretical reference for the practical application of composite absorbing materials.
