Abstract

In this work we investigate the hydration water in polyelectrolyte monolayers of Poly- (allylamine hydrochloride) (PAH) and Poly-(diallyldimethyl ammonium chloride) (PDADMAC). The polyelectrolytes are adsorbed to colloidal particles in aqueous or salt solution. The zeta-potential and the 1H NMR transverse relaxation rate of the water protons are determined in dependence of polymer surface coverage. The relaxation of the solvent in colloidal dispersions is increased by solvent immobilisation in surface layers, and thus monitors the average amount and motional dynamics of solvent molecules at the surface.
