▎ 摘　　要

Novel multilayer ultrathin films comprised of graphene oxide (GO) and poly(vinyl alcohol) (PVA) were fabricated through a layer-by-layer (LBL) assembly technique. GO could self-assemble onto quartz substrates alternately with PVA via hydrogen-bonding interactions. X-ray diffraction, atomic force microscopy, and transmission electron microscopy analysis revealed that GO was exfoliated to monolayers. The ultrathin films, with PVA/GO multilayer structures fabricated by LBL assembly, were characterized by ultraviolet-visible spectroscopy and X-ray diffraction analysis, confirming that the assembly of the multilayer films was quantitative and reproducible.
