摘要：

In order to promote the application of graphene oxide grafted carbon fiber (CF-GO) as a functional reinforcement phase in concrete, the electromagnetic characteristics of CF-GO and CF are compared and analyzed by testing their electromagnetic parameters. The effects of CF-GO on the electromagnetic shielding and wave absorbing properties of concrete are studied by testing the electromagnetic shielding efficiency and reflectivity of CF-GO reinforced concrete (CF-GORC), and compared with CF. The wave absorbing and electromagnetic shielding mechanism of CF-GORC are analyzed by testing its conductivity and electromagnetic parameters. The results show that the graft of GO can enhance the dielectric loss capacity of CF, but has no effect on the magnetic loss capacity of CF. CF-GO can improve the electromagnetic shielding and wave-absorbing properties of concrete. As CF-GO content increases, the electromagnetic shielding efficiency and effective absorption bandwidth of CF-GORC increase, and the reflectivity of CF-GORC decreases. The improvement effect of CF-GO on the electromagnetic shielding and wave absorption properties of concrete is better than that of CF. CF-GO can improve the electrical conductivity and dielectric loss capacity of concrete. After the addition of CF-GO, the conductive loss and polarization loss of concrete are improved, thus enhancing the electromagnetic shielding and wave-absorbing properties of concrete.
