采用热解法制备了碳氮共掺杂MoO 2纤维。研究了其结构、形貌、组成、复介电常数和微波吸收性能。MoO 2纤维具有一维形态，具有相对低的氮物种（2.26重量%）和高碳物种（11.0重量%）。当填料含量为20%时，厚度为3.5mm的MoO 2纤维/蜡复合材料的最小反射损耗为-40.1dB，最佳有效带宽为4.2GHz，小于-10dB。(C)2018由Elsevier B. V.出版
The C and N co-doped MoO2 fibers were synthesized from an organic-inorganic hybrid by pyrolysis. The structure, morphology, composition, complex permittivity and microwave absorption performance were investigated. The MoO2 fibers possess one-dimensional morphology with relatively low nitrogen species (2.26 wt%) and high carbon species (11.0 wt%). The MoO2 fibers/wax composite with 20% filler content achieved a minimum reflection loss of -40.1 dB with a thickness of 3.5 mm, and an optimum effective bandwidth of less than -10 dB of 4.2 GHz with a thickness of 2.0 mm. The MoO2 fibres is a promising candidate as a lightweight and wide-frequency electromagnetic wave absorber. (C) 2018 Published by Elsevier B.V.
