▎ 摘　　要

A large-area reduced graphene oxide (rGO)/poly(vinyl alcohol) (PVA) film with excellent microwave absorption properties has been prepared by a simple solution processing method. Excellent interfacial interaction between GO and PVA has been realized due to the molecule-level dispersion. Characterization by X-ray diffraction, the Fourier transform infrared (FT-IR) spectra, X-ray photoelectron spectrum and Raman spectroscopy has confirmed the reduction process of GO in the composites. The rGO/PVA film exhibits excellent microwave absorbing properties in the range of 2-18 GHz. It is expected to be a promising candidate as a microwave absorbing material.
