WebSchaaf et al. suggest that the exponential growth occurs when one of the polyelectrolytes diffuses “into” the entire film during deposition. 8 Upon addition of the oppositely charged polyelectrolyte, the previously adsorbed polyelectrolyte diffuses “out” of the whole film to form a very thick polyanion-polycation complex at the surface. WebOct 1, 2024 · Three concentrations of SNP-AL were produced by varied alginate into 0.1, 1, and 5 mM. UV-Vis spectroscopy was used to characterize their specific wavelength at 400 nm. Subsequently, 10 bilayers thin film were established between PDADMAC and SNP-AL via polyelectrolyte multilayer technique. These were characterized by SEM and AFM.
