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.

A quartz crystal microbalance (QCM) was used to monitor dextransucrase (DSase)-catalyzed polysaccharide elongation on the glucose-/maltose-ended self-assembly monolayer (SAM) surfaces. Kinetic parameters of the enzymatic elongation indicate that maltose is a promising substrate acceptor for DSase.
