Download or read book Polyelectrolyte Complexes in the Dispersed and Solid State I written by Martin Müller and published by Springer. This book was released on 2014-07-08 with total page 236 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive account of the modern theory for the dynamical properties of polymer solutions. The theory has undergone dramatic evolution over the last two decades due to the introduction of new methods and concepts that have extended the frontier of theory from dilute solutions in which polymers move independently to concentrated solutions where many polymers converge. Among the properties examined are viscoelasticity, diffusion, dynamic light scattering, and electric birefringence. Nonlinear viscoelasticity is discussed in detail on the basis of molecular dynamical models. The book bridges the gap between classical theory and new developments, creating a consistent picture of polymer solution dynamics over the entire concentration range.

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: This book comprehensively reviews the synthesis, characterization and application aspects of linear and crosslinked synthetic polyampholytes - simple model of biopolymers - starting from the 1950's. The synthetic strategy of "annealed", "quenched" and "zwitterionic" polyampholytes, the properties of polyampholytes in solutions and in gel state are considered. The complexation ability of polyampholytes with respect to transition metal ions, ionic surfactants, dyes and organic probes polyelectrolytes, proteins and colloid particles is discussed. Stimuli-sensitive behavior of various amphoteric gel and membrane systems demonstrating rhythmically phenomenon similar to that of heart beat, deformation, oscillation or self-oscillation phenomena stimulated by temperature, pH and electric field are illustrated. Catalytic properties of synthetic polyampholytes simulating the function of enzymes are also considered.

Available in PDF, EPUB and Kindle. Book excerpt: The theoretical background of this work is concerning with the drug loaded polyelectrolyte multilayers (PEM) modified by the host-guest interaction of biocompatible hyperbranched core-shell glycopolymers. The glycopolymer in this work is the hyperbranched polyethyleneimine that was modified with maltose moieties using reductive amination. Thus, the use of glycohyperbranched polymers for drug delivery would allow the avoid naturally occurring drug resistance due to decreased transporter activity. Concerning preparative method, PEM was fabricated using layer-by-layer (LbL) processes involve the sequential deposition of two polyions that physically bond together. Control was taken on the stoichiometric ratio related to cationic and anionic repeating units, which was chosen close to zero for the final applied PEM. Concerning analytical methods, a couple of physical-chemical methods were applied to characterize colloid stability, adhesiveness, drug loading and release of fabricated PEM. In conclusion, a highly sable and sustainable PEM coats on a surface of an activated solid substrate has been fabricated with an efficient ability to recycle the charged molecule for more than 24 times.

Download or read book Adhesive Properties of Wet Polyelectrolyte Multilayer Films and Electrophoretic Deposition of Polyelectrolyte Complexes written by Chao Li and published by . This book was released on 2016 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weak polyelectrolyte multilayers prepared by using layer-by-layer (LbL) technique are known to become sticky upon contact with water and behave as a viscoelastic fluid, but the full extent of this wet adhesive property is not fully understood. In this study, the wet adhesive performance of polyelectrolyte multilayers consisting of branched poly(ethylene imine) and poly(acrylic acid) under controlled conditions was investigated by using a 90° peel test. The peel force is highest under neutral condition, and it decreases in acidic/basic environment. The addition of metal ions changes the peel force, either increasing it or decreasing it based on the nature of the metal ion. Addition of Cu2+ stiffens multilayers, preventing multilayers from acting as an effective wet adhesive. The films are also characterized with zeta potential and shear rheometry, and the adhesiveness can be recovered by rewetting for at least 5 times. This polyelectrolyte based wet adhesive can be adhered to soft, wet surfaces like biological tissues such as liver. These multilayer films in this work show wet adhesive properties, however, the layer by layer technique used to fabricate these films requires several steps and take a long time. Therefore, new methods are needed to make these thin films. Spin-assisted LbL assembly, spray-assisted LbL assembly and electric field-assisted LbL assembly are widely studied because they are simple and time-saving. Electric field-assisted LbL assembly has been gaining an increasing interest. One option for realizing this may be the electrophoretic deposition of weak polyelectrolyte complexes, made by mixing polyelectrolytes of opposite charge together, has not been studied yet. Therefore, electrodeposition of polyelectrolyte complexes under different conditions (i.e. pH, ratio of polycation and polyanion, concentration of polyelectrolyte complexes, concentration of salt and type of electric field) was investigated in this work. Polyelectrolyte complexes at moderate pH values and at the ratio of polycation and polyanion at 20 shows highest electrophoretic mobility. The thickness of polyelectrolyte complex film decreases with decreasing the concentration of polyelectrolyte complexes while the thickness increases when a proper amount of salt is added during preparing polyelectrolyte complexes. Under controlling pulse current at 10mA, a thicker film can be achieved but the surface is rougher compared with one prepared by using pulse potential at 10V. This work provides insight into both the wet adhesive properties of polyelectrolyte multilayers and electrophoretic deposition of polyelectrolyte complexes.
