We report on the influence of ionic strength of polyelectrolyte solutions on the growth of multilayers made of polyvinylsulfate and a series of aromatic ionenes of decreasing charge density. Stable multilayers growth was only possible for polyelectrolytes of sufficiently high charge density, confirming the existence of a critical charge density for the formation of multilayers. We also show that,...
Multilayered assemblies of alternate polyelectrolytes have been synthesized by dipping charged silicon wafers successively into solutions of polyelectrolytes of opposite charge. In this study, three types of assemblies and several thicknesses are investigated by Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), in combination with other characterization techniques ( X-Ray Photoelectron Spectroscopy...
