Polyelectrolyte multilayers


The properties of these systems are studied by e.g. ellipsometry, x-ray and neutron reflectometry and atomic force microscopy.

Moreover, the extent of polyelectrolyte adsorption on the substrate is followed by quartz-crystal microbalance with dissipation monitoring (QCM-D), which gives information about the viscoelastic properties of the growing multilayer. They are compared with AFM indentation experiments. Parameters of current studies are molecular weight and substrate properties.

The general question addresses the correlation between structure, dynamics and swelling behavior of these multilayers.
