Preparation Mechanism of Electrostatic Self-assembled Polyelectrolyte Film Using Quartz Crystal Microbalance
Electrostatic layer-by-layer (LbL) self-assembly is widely used in sequential adsorption of nanometer-thick monolayers of oppositely charged polyelectrolytes to form a multi-layer film with molecular-level control over the architecture.To offer functional material for the potential application,this paper exploits PDDA and PSS as polycation and polyanion for LbL self-assembly to fabricate polyelectrolyte nanocomposite films.The preparation and film-growing mechanism is investigated under the influences of multi-factor such as polyelectrolyte concentration,ionic strength,and assembling duration using quartz crystal microbalance (QCM).The research results indicate the formation mechanism of multi-layer PDDA/PSS films and offer fundamental basis for the optimum preparation of polyelectrolyte films.
