Novel multilayer ultrathin ?lms comprised of graphene oxide (GO) and poly(vinyl al-
cohol) (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 ?lms, with PVA/GO multilayer structures fabricated by LBL assembly, were characterized by ultraviolet-visible spectroscopy and X-ray diffraction analysis, con?rming that the assembly of the multilayer ?lms was quantitative and reproducible.
