The dependence of zeta-potential on the number of polyelectrolyte layers obtained at three different polyelectrolyte concentrations. c(PAH) = c(PSS) = 0.001 mol·dm−3 (blue dots); c(PAH) = c(PSS) = 0.003 mol·dm−3 (red dots); and c(PAH) = c(PSS) = 0.01 mol·dm−3 (green dots). PAH: poly(allylamine hydrochloride); PSS: sodium poly(4-styrenesulfonate).
