Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes research that aimed at a better understanding of the parameters and mechanisms that govern the adsorption of polyelectrolytes on an oppositely charged polyelectrolyte brush. The work was motivated through earlier results described by Zhang, who observed for some cases a very strong templating effect of a PEL brush when this brush was used as a substrate for the so-called layer-by-layer deposition process. The formation of PEL-PEL complexes at surfaces is fairly well understood. Layer formation is due to the interplay between number of charges, solubility (swellability) and the presence of hidden charges. Additionally, "overcompensation" can occur due to kinetic reasons (irreversible processes) in weak-strong system and popping up of previously hidden charges in weak-weak system. We coined the term "Trojan Horse" (of Greek Mystery) mechanism for the fabrication of multilayer deposition.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist.

Download or read book Polymer Brushes written by Rigoberto C. Advincula and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials scientists, polymer chemists, surface physicists and materials engineers will find this book a complete and detailed treatise on the field of polymer brushes, their synthesis, characterization and manifold applications. In a first section, the various synthetic pathways and different surface materials are introduced and explained, followed by a second section covering important aspects of characterization and analysis in both flat surfaces and particles. These specific surface initiated polymerization (SIP) systems such as linear polymers, homopolymers, block copolymers, and hyperbranched polymers are unique compared to previously reported systems by chemisorption or physisorption. They have found their way in both large-scale and miniature applications of polymer brushes, which is covered in the last section. Such 'hairy' surfaces offer fascinating opportunities for addressing numerous problems of both academic and, in particular, industrial interest: high-quality, functional or protective coatings, composite materials, surface engineered particles, metal-organic interfaces, biological applications, micro-patterning, colloids, nanoparticles, functional devices, and many more. It is the desire of the authors that this book will be of benefit to readers who want to "brush-up on polymers".

This book was released on 2011 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this dissertation is the synthesis, development and application of polymer brushes for the fractionation of complex mixtures of peptides and digested proteins prior to MALDI-MS analysis. Even though MALDI-MS analysis is increasingly used in proteomic applications, this method of analysis suffers loss of performance in the analysis of mixtures due to the ion suppression effect i.e. basic peptides are more easily ionized and suppress the ionization of other less basic peptides. In the approach taken a polyelectrolytic polymer brush containing randomly polymerized NIPAAM-co-MAA was utilized as a mixture fractionation substrate. This polymer brush was chosen because the long polymer chains are expected to offer a three dimensional volume for adsorption of targeted analytes. In this work fractionation occurs as a result of electrostatic attraction or repulsion between the negatively charged polymer surface and positively or negatively charged analytes in solution, respectively. While the investigations require additional work, preliminary results demonstrate that higher capacity for peptide binding is achieved at longer photopolymerization times. However, the results also suggest that a much more aggressive method is needed to release the peptides bound on the surface of this type of polymer brush.

This book was released on 2013 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyelectrolytes (PE) are the least understood polymeric systems due to their complex behavior that arises because of the intimate connection between charge and conformation. To address this challenge, my research focuses on understanding the responsive behavior of weak polyelectrolyte brushes to different stimuli such as pH, type of ion and ionic strength. In this work, weak polyelectrolyte brushes made of poly(methacrylic acid) (PMAA) and random copolymer brushes incorporating hydroxyethyl methacrylate (HEMA) as co-monomer were studied. The polymer brushes were synthesized by both "grafting to" and "grafting from" approaches and were characterized mainly by ellipsometry and neutron reflectometry. Several methods for preparing alkyne-decorated substrates suitable for "click" chemistry are described. For each method, factors that control film thickness and content of alkyne groups were investigated. Azide terminated PMAA and poly(vinyl-dimethylazlactone) polymers were tethered to alkyne-bearing poly(glycidylmethacrylate) surface layers via click reactions. It was observed that the alkyne content obtained by these approaches was sufficiently high and was not the limiting factor for the click reaction of azide-capped polymers. A method to self-consistently determine water content of PE films using neutron reflectometry under different hydration conditions is reported. Multiple data sets were modeled with constrained fittings to obtain dry polymer mass density, layer thickness and PE brush profiles into different pH solutions. The influence of monovalent ions from the cationic Hofmeister series on the structure and swelling behavior of weak polyelectrolyte brushes was also investigated. It was found that the scaling behaviors of PMAA brushes with respect to salt concentration are similar in presence of different salts; however, the cross-over salt concentration at which the transition occurs is different for each type of salt and can be explained by its position in Hofmeister series. Finally, some preliminary results concerning calcium carbonate mineralization of PMAA brushes as a function of concentration of organic additive are reported. Calcium carbonate films were obtained by polymer-induced liquid precursor (PILP) strategy, using an ammonia diffusion method. Various characterizations show that as the concentration of additive is increased, the extent of mineralization decreases.
