    Highly ordered monolayers of graphite oxide (GO) were assembled on hydrophilic substrates by the Langmuir–Blodgett technique. AFM observations confirm that the film architecture can be controlled by the pH and GO concentration in the subphase. At pH 10, films drawn over a 50 mg/L GO suspension consist of well-aligned, closely interlocked single or bilayer graphene oxide particles without the presence of larger gaps or overlaps between them.
