Excellent electromagnetic wave absorption ability and effective absorption bandwidth have been the development direction of electromagnetic wave absorbing materials. In this paper, a rational structural design is proposed. Graphene oxide (GO)/polyaniline (PANI) layer was formed on the surface of the natural material bamboo powder (BP) by an interfacial polymerization process. The combination of GO and PANI improves the impedance mismatch of the conductive polymer PANI. Enhanced dielectric storage and loss capability of the composite GO/PANI/BP. The addition of BP brings more electromagnetic wave loss channels to the composite GO/PANI/BP. This unique structure facilitates the construction of a three-dimensional electromagnetic wave-reflecting cavity, which improves the absorptive capacity of the composite by introducing effective multiple reflections. The conductivity of GO/PANI/BP was 1.78 (±0.06) S/cm. When filled to 30 wt%, a minimum reflection loss (RLmin) of −44 dB at 9.36 GHz and a thickness of 3 mm, and an effective absorption bandwidth ( |
