Abstract
Polyelectrolyte multilayers were deposited onto polystyrene and melamine
formaldehyde latex particles by means of consecutive adsorption.
Two different methods of multilayer growth were employed. First,
adsorption of polyelectrolytes at a concentration exceeding saturation
amounts was combined with the removal of the nonbound polyelectrolyte
by means of centrifugation. Second, adsorption of polyelectrolyte
was performed at a concentration just sufficient for saturation coverage.
Both methods yielded continuous layer growth. The process of film
formation was followed by electrophoresis, dynamic Eight scattering,
single particle light scattering and fluorescence intensity measurements.
Layer deposition onto partially crosslinked melamine resin latex
particles, which were soluble at pH values of less than 1.6, resulted
in the production of three-dimensional thin polyelectrolyte shells
upon dissolving the core. The ultrathin shells were observed by means
of scanning and transmission electron microscopy.
