“…19,20 A modification of the thin film pressure balance (TFPB) using the porous-plate technique was used to extend the disjoining pressure range to higher values. This method that has been applied by several authors 21,22 was recently implemented in our laboratory. Details of our apparatus and the experimental technique are given in the Materials and Methods.…”

The stability of wetting films of two ionic liquids, 1-octyl-3-methylimidazolium tetrafluoroborate, [C8mim][BF4], and 1-ethanol-3-methylimidazolium tetrafluoroborate, [C2OHmim][BF4], on alumina was assessed through the measurement of disjoining pressure isotherms, which represent the dependence of the disjoining pressure on the film thickness. Two experimental techniques were used at low and high disjoining pressure, respectively: captive bubble and modified thin film pressure balance. Theoretical predictions of the disjoining pressure isotherms were made using the microscopic approach of London and Hamaker based on the van der Waals contribution to the disjoining pressure. Good agreement was found between the experimental and the theoretical isotherms for [C8mim][BF4], whereas in the case of [C2OHmim][BF4], the experimental data are slightly shifted toward larger thickness, especially at higher disjoining pressures. An interpretation of these results is given in terms of a corresponding-states principle argument applied to the surface tension and the use of auxiliary molecular dynamics data. The conclusion is that although both Coulomb and dispersion interactions contribute to determine the bulk properties of these ionic liquids the surface properties are mainly related to the dispersive forces.

Combining imaging ellipsometry and grazing incidence small angle X-ray scattering for in situ characterization of polymer nanostructures

et al. 2009

A combination of microbeam grazing incidence small angle X-ray scattering (muGISAXS) and imaging ellipsometry is introduced as a new versatile tool for the characterization of nanostructures. muGISAXS provides a local lateral and depth-sensitive structural characterization, and imaging ellipsometry adds the position-sensitive determination of the three-dimensional morphology in terms of thickness, roughness, refractive index, and extinction coefficient. Together muGISAXS and imaging ellipsometry enable a complete characterization of structure and morphology. On the basis of an example of buildup of nanostructures from monodisperse colloidal polystyrene nanospheres on a rough solid support, the scope of this new combination is demonstrated. Roughness is introduced by a dewetting structure of a diblock copolymer film with one block being compatible with the colloidal nanoparticles and one block being incompatible. To demonstrate the potential for kinetic investigations, muGISAXS and imaging ellipsometry are applied to probe the drying process of an aqueous dispersion of nanospheres on such a type of rough substrate.
