Layer-by-layer surface freezing of linear alcohols at the graphite/liquid interface

Differential scanning calorimetry (DSC), incoherent elastic neutron scattering, and neutron diffraction are used to demonstrate the presence of adsorbed solid multilayers of linear alcohols at the graphite-liquid alcohol interface. All alcohols studied (C-5-C-18) are found to form at least one monolayer. In addition all the even alcohols investigated (C6OH to C18OH) show multilayer formation. However, only the short odd alcohols (C5OH to C11OH) clearly exhibit additional features indicating multilayer formation. (C) 2003 Elsevier Inc. All rights reserved.
