Hybrid Langmuir-Blodgett monolayers of graphite oxide nanosheets

Highly ordered monolayers of graphite oxide (GO) were assembled oil 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 (C) 2009 Elsevier Ltd All rights reserved
