| Popis: | NiCo alloy nanoparticles/nanoporous carbon (NiCo/NPC) composites with multilayered structure were synthesized by in situ pyrolysis of the bimetallic NiCo-based metal-organic frameworks. Designable electromagnetic parameters accompanied with a low density, ultrathin thickness, wide absorption bandwidth and strong electromagnetic wave absorption were achieved in the NiCo/NPC composites. An optimum RL (reflection loss) value of −51 dB at 17.9 GHz with an effective absorbing bandwidth (RL |
