Abstract
We report on the effect of mutual polyelectrolyte charge and secondary interactions on the formation of polyelectrolyte multilayer films of a lowly charged copolymer of acrylamide and [3-(2-methylpropionamido)propyl]trimethylammonium chloride, AM-MAPTAC 10 (10 mol % of cationic monomers), and poly(acrylic acid) (PAA). These multilayer films were constructed on planar substrates by the sequential adsorption of AM-MAPTAC 10 and PAA at different pH conditions. Surface plasmon resonance spectroscopy (SPRS), quartz crystal microbalance (QCM), and atomic force microscopy (AFM) were employed to follow the film formation process. While AM-MAPTAC 10 is permanently charged, the ionization of PAA is adjusted by changing the pH of the adsorption solutions. In contrast with previous studies, it is shown that multilayer formation with one polyelectrolyte with a charge density of 10 mol % is possible. However, the multilayer growth follows a different pattern depending on the relative charge density of PAA. At low pH, w...
