Download or read book Paper Chemistry written by J.C. Roberts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the title of this book is Paper Chemistry, it should be considered as a text about the chemistry of the formation of paper from aqueous suspensions of fibre and other additives, rather than as a book about the chemistry of the raw material itself. It is the subject of what papermakers call wet-end chemistry. There are many other excellent texts on the chemistry of cellulose and apart from one chapter on the accessibility of cellulose, the subject is not addressed here. Neither does the book deal with the chemistry of pulp preparation (from wood, from other plant sources or from recycled fibres), for there are also many excellent texts on this subject. The first edition of this book was a great success and soon became established as one of the Bibles of the industry. Its achievement then was to collect the considerable advances in understanding which had been made in the chemistry of papermaking in previous years, and provide, for the first time, a sound physico chemical basis of the subject. This new edition has been thoroughly updated with much new material added. The formation of paper is a continuous filtration process in which cellulosic fibres are formed into a network which is then pressed and dried. The important chemistry involved in this process is firstly the retention of col loidal material during filtration and secondly the modification of fibre and sheet properties so as to widen the scope for the use of paper and board products.

Download or read book Tailoring Surfaces written by Nicholas D. Spencer and published by World Scientific. This book was released on 2011 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of the book is the modification of surfaces to tailor them for a specific purpose. Using this method of surface modification, materials chosen for their bulk properties (tensile strength, temperature stability, density, price can be optimized for any particular application, which can lead to improved hardness, biological inertness or activity, corrosion resistance, low or high friction or adhesion, water repellency or wettability, or catalytic activity. The works of the author — many of his crucial papers are included — touches upon these surface properties and spans fields including catalysis, analytical surface science, self-assembled monolayers, tribology, biomaterials, superhydrophobicity and polymer coatings.
Download or read book Block Copolymers written by Nikos Hadjichristidis and published by John Wiley & Sons. This book was released on 2003-04-28 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers may be classified as either homopolymers, consisting of one single repeating unit, or copolymers, consisting of two or more distinct repeating units. Block copolymers contain long contiguous blocks of two or more repeating units in the same polymer chain. Covering one of the hottest topics in polymer chemistry, Block Copolymers provides a coherent overview of the synthetic routes, physical properties, and applications of block copolymers. This pioneering text provides not only a guideline for developing synthetic strategies for creating block copolymers with defined characteristics, but also a key to the relationship between the physical properties of block copolymers and the structure and dynamics of materials. Covering features of the chemistry and physics of block copolymers that are not found in comparable texts, Block Copolymers illustrates the structure-activity relationship of block copolymers and offers suggestions for the design of specific applications. Divided into five sections-Block Copolymers includes chapters on: * Block Copolymers by Chemical Modification of Precursor Polymers * Nonlinear Block Copolymers * Adsorption of Block Copolymers at Solid-Liquid Interfaces * Theory of Block Copolymer Segregation * Phase Transformation Kinetics * Block Copolymer Morphology * Block Copolymer Dynamics Polymer chemists, physicists, chemical engineers, and materials scientists, as well as graduate students in polymer science, will find Block Copolymers to be an invaluable text.

Download or read book Adsorption of Polyelectrolyte on Colloidal Silica written by YongWoo Shin and published by . This book was released on 2001 with total page 398 pages. 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.

Download or read book Polyelectrolyte Adsorption and Self assembly on Charged Surfaces written by Hao Cheng and published by . This book was released on 2005 with total page pages. 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.
