Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, interactions between surfaces with adsorbed highly branched polyelectrolytes were studied with the colloidal probe technique. By studying the adsorption behavior of highly branched polyelectrolytes, the lateral distribution of the surface charge could be tuned by the appropriate adsorption conditions. By choosing different polyelecrtrolytes, namely highly branched poly(ethylenimine) (PEI) and poly(amido amine) (PAMAM) dendrimers, it was possible to investigate the forces between homogeneously charged layers, as well as surfaces compodes of charge patches where both the patch size and the distance between them could be tuned. The output of the force measurements allowed not only to know its dependence on the surface charge heterogeneity, but also some properties of the individual adsorbed polymers.

Available in PDF, EPUB and Kindle. Book excerpt: Polyelectrolyte adsorption on charged surfaces is of fundamental importance in materials science and biology. Thermodynamic models based on electrostatics and statistical mechanics have been developed in this dissertation to study polyelectrolyte adsorptions. The chemical potentials of the surface components are equated to their counterparts in the bulk solution by minimizing the free energy. This method enables us to self-consistently analyze polyelectrolyte adsorption including interactions neglected by Poisson-Boltzmann approach and equivalent mean field models.

Available in PDF, EPUB and Kindle. Book excerpt: The adsorbed amounts and interfacial conformations of weak cationic polyelectrolytes (2.5 k and 31 k of poly (dimethylaminoethyl methacrylate), DMAEMA) on colloidal silica were examined in the context of the influence of chain conformation, and the roles of ionization and counterions. The mobility of the polymer in solution is altered at the Bjerrum length, indicating counterion condensation and a conformation change. Variations in pH altered the backbone and surface charge densities, changing the density of contact points for adsorption. Variations in ionic strength screened repulsions among adsorbed oligomers, an effect most apparent at low ionic strengths. NMR solvent relaxation data provided substantial evidence for differences in the anchoring of DMAEMA oligomers and adsorbed trains of a nonionic homopolymer such as polyethylene oxide. DMAEMA adsorbs at a small number of discrete points on side chains while for polyethylene oxide, every monomer on the main backbone can potentially adhere to the surface, giving a less mobile interface from the perspective of the solvent. The other important feature of this model system was that the polycation charge density was greater than that of the substrate. We demonstrate, quantitatively, that the charge overcompensation observed on the isotherm plateau can be directly attributed to the denser positive charge on the adsorbing polycation, and that the ultimate coverage obtained corresponds to the adsorption of one oligomer onto each underlying negative silica charge, when the silica charge is most sparse, at pH 6. This limiting behavior breaks down at higher pHs where the greater silica charge density accommodates single chains adsorbing onto multiple negative sites. Ultimately at the highest pH's, a regime is approached where coil size, not charge distribution, limits the ultimate coverage. Surface charge enhancement is not a cause for charge overcompensation, but a consequence. High affinity adsorption isotherms at dilute concentration were found for high molecular weight DMAEMA. As pH increases, the bound mass decreases more rapidly than the adsorbed amount, suggesting that the DMAEMA layers may contain loops and tails of higher mobility, before adsorption disappears altogether.
