Abstract:

A naval hybrid buckypaper was fabricated by vacuum filtration method with monodispersed solution of Fe3O4 decorated carbon nanotubes (CNTs), which was easy to be infiltrated by resin and can be co-cured with polymer composites. The morphology, element composition, pore size distribution, and magnetic of hybrid buckypaper were characterized by field-emission scanning electron microscope (FE-SEM), energy dispersive spectrometer (EDS), Barret-Joyner-Halenda (BJH) and vibrating sample magnetometer. The electromagnetic parameters of CNTs composite and hybrid buckypaper attached CNTs composite were investigated in the frequency range of 8.2-18 GHz with wave guide method and the reflection loss can be calculated. The hybrid buckypaper with only absorbing thickness of 0.1 mm attached CNTs composite possesses much broader absorbing bandwidth and larger reflectivity than those of CNTs composite, nearly all of which reflectivity is below -10 dB in frequency range of 8.2-18 GHz and the minimum value is -43.18 dB at 15.42 GHz.

Key words: Fe3O4/decorated CNTs, hybrid buckypaper, CNTs composite, electromagnetic parameter, reflection loss
