Ftir studies of molecular assemblies on solid surfaces

The first observation of spontaneous assembly from solution of a well-ordered polymer monolayer is reported for the system poly(1-octadecene-co-maleic anhydride) adsorbed from ethanol solution onto silver substrates. Analysis by grazing incidence reflection infrared spectroscopy suggests that these monolayers compare quite favorably in terms of orientational order with Langmuir-Blodgett films made from the same material. Thermal stability of these films is significantly enhanced compared to analogous monomeric monolayers of fatty acids. © SPIE.
