摘要：

Three-dimensional nano-flower structure of MoS2/PANI nanocomposites were successfully fabricated via the in situ polymerization method. The best reflection loss could reach - 50.57 dB at 5.04 GHz with the thickness of 5.0 mm and the efficient absorption bandwidth (RL <= - 10 dB) was about 2.08 GHz when the mass ratio of MoS2/PANI was 5:5. Additionally, in the case of satisfying effective electromagnetic wave absorption, other two effective and even wider absorption bandwidth could achieve 4.96 GHz (13.04-18.00 GHz) and 3.68 GHz (8.08-11.76 GHz) at the thickness of 2.0 mm and 3.0 mm, respectively. According to the electromagnetic parameters' analyses, the more multi-interfaces introduced by the construction of such three-dimensional nano-flower structure, the more multi-polarization and reflection could be occurred, the better electromagnetic wave absorption could be achieved. The results indicated that MoS2/PANI nanocomposites were the promising electromagnetic wave absorbing materials.
