| Abstract
| - Molecular dynamics simulations of polyelectrolyte multilayering on a charged spherical particle revealedthat the sequential adsorption of oppositely charged flexible polyelectrolytes proceeds with surface chargereversal and highlighted electrostatic interactions as the major driving force of layer deposition. Far frombeing completely immobilized, multilayers feature a constant surge of chain intermixing during the depositionprocess, consistent with experimental observations of extensive interlayer mixing in these films. Theformation of multilayers as well as the extent of layer intermixing depends on the degree of polymerizationof the polyelectrolyte chains and the fraction of charge on its backbone. The presence of ionic pairs betweenoppositely charged macromolecules forming layers seems to play an important role in stabilizing themultilayer film.
