N2 - In response to the requirement of light-weight absorbing materials,a new type of flexible composite buckypaper were prepared with graphene oxide (GO)buckypaper and magnetic nanoparticles (Fe3 O4)and acted as a lightweight electromagnetic wave absorbing material,which is expected to replace the wave-absorbing paint and simplify the molding process to realize the control of wave-absorbing performance. First, γ-aminopropyltriethoxysilane (KH-550)was used to organically modify Fe3 O4 nanoparticles to prepare Fe3 O4 -GO composite nanoparticles with uniform dispersion and electromagnetic double loss performance,and then GO and Fe3 O4 -GO buckypapers were prepared by solvent evaporation deposition method. The results show that NH2 -Fe3 O4 is stably attached to the GO sheet. When the mass ratio of Fe3 O4 to GO is 4 ∶ 6,the input impedance Zin is closest to the free space impedance Z0,which means the impedance matching performance of the composite buckypaper is the best. Furthermore,Fe3 O4 -GO composite buckypaper has stronger absorbing performance than composite nanoparticles. When the mass ratio of Fe3 O4 to GO is 4 ∶ 6 and 5 ∶ 5,respectively,the reflection loss(RL)values are less than - 10 dB in the 2—18 GHz frequency band.
