Available in PDF, EPUB and Kindle. Book excerpt: Colloid–polymer mixtures are subject of intensive research due to their wide range of applicability, for instance in coatings and food-stuffs. This thesis constitutes a fundamental investigation towards a better control over the stability of such suspensions. Through the chapters, different key parameters governing the stability of colloid–polymer mixtures are explored. How the colloid (pigment) shape and the effective polymer-colloid affinity modulate the stability of the suspension are examples of these key parameters. Despise the mostly theoretical results presented, the thesis is written in a format accessible to a broad scientific audience. Some of the equations of state presented might of direct use to experimentalists. Furthermore, new theoretical insights about colloid–polymer mixtures are put forward. These include four-phase coexistences in effective two-component, quantification of depletant partitioning at high colloidal concentrations, multiple re-entrant phase behaviour of the colloidal fluid–solid coexistence, and a condition where polymers are neither depleted nor adsorbed from/to the colloidal surface.
Download or read book Colloids and the Depletion Interaction written by Henk N.W. Lekkerkerker and published by Springer. This book was released on 2011-05-23 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloids are submicron particles that are ubiquitous in nature (milk, clay, blood) and industrial products (paints, drilling fluids, food). In recent decades it has become clear that adding depletants such as polymers or small colloids to colloidal dispersions allows one to tune the interactions between the colloids and in this way control the stability, structure and rheological properties of colloidal dispersions. This book offers a concise introduction to the fundamentals of depletion effects and their influence on the phase behavior of colloidal dispersions. Throughout the book, conceptual explanations are accompanied by experimental and computer simulation results. From the review by Kurt Binder: "They have succeeded in writing a monograph that is a very well balanced compromise between a very pedagogic introduction, suitable for students and other newcomers, and reviews of the advanced research trends in the field. Thus each chapter contains many and up to date references, but in the initial sections of the chapters, there are suggested exercises which will help the interested reader to recapitulate the main points of the treatment and to deepen his understanding of the subject. Only elementary knowledge of statistical thermodynamics is needed as a background for understanding the derivations presented in this book; thus this text is suitable also for advanced teaching purposes, useful of courses which deal with the physics for soft condensed matter. There does not yet exist any other book with a similar scope..... The readability of this book is furthermore enhanced by a list of symbols, and index of keywords, and last not least by a large number of figures, including many pedagogic sketches which were specifically prepared for this book. Thus, this book promises to be very useful for students and related applied sciences alike." Eur. Phys. J. E (2015) 38: 73

Available in PDF, EPUB and Kindle. Book excerpt: This monograph represents an extension of the author''s original PhD thesis and includes a more thorough discussion on the concepts and mathematics behind his research works on the foam model, as applied to studying issues of phase stability and elasticity for various non-closed packed structures found in fuzzy and colloidal crystals, as well as on a renormalization-group analysis regarding the critical behavior of loop polymers upon which topological constraints are imposed. The common thread behind these two research works is their demonstration of the importance and effectiveness of utilizing geometrical and topological concepts for modeling and understanding soft systems undergoing phase transitions.

Available in PDF, EPUB and Kindle. Book excerpt: Academic and industrial research around polymer-based colloids is huge, driven both by the development of mature technologies, e.g. latexes for coatings, as well as the advancement of new materials and applications, such as building blocks for 2D/3D structures and medicine. Edited by two world-renowned leaders in polymer science and engineering, this is a fundamental text for the field. Based on a specialised course by the editors, this book provides the reader with an invaluable single source of reference. The first section describes formation, explaining basic properties of emulsions and dispersion polymerization, microfluidic approaches to produce polymer-based colloids and formation via directed self-assembly. The next section details characterisation methodologies from microscopy and small angle scattering, to surface science and simulations. The final chapters close with applications, including Pickering emulsions and molecular engineering for materials development. A comprehensive guide to polymer colloids, with contributions by leaders in their respective areas, this book is a must-have for researchers and practitioners working across polymers, soft matter and chemical and molecular engineering.
Download or read book An Introduction to Polymer Colloids written by Françoise Candau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest in the subject of Polymer Colloids over the last twenty five years or so has been very large resulting now in major international conferences on an annual basis and many national ones as well. The interest stems not only from the wide range of applications of these materials but also from a curiosity as to the mechanism of formation and their growing use as model particles to investigate fundamental aspects of physics and chemistry. In July 1988 a NATO Advanced Study Institute was held in Strasbourg, France, at the Centre St. Thomas. As an educational introduction to this I nstitute a series of eight lectures was given to cover the fundamental aspects of the subject. These eight lectures have now been compiled into an Introductory Text covering, emulsion poly merization, dispersion polymerization, inverse emulsion polymerization, the morphology of copolymer latices, the colloidal properties of latices, characterization methods and rheology. It is hoped that these will serve a wide audience, undergraduates, graduate-students and research workers, both in industry and academe. The chapters all contain review material up to date at the time of publication. fhe 1988 NATO Advanced Study I nstitute was made possible by a grant from the NATO-AS I programme and the following companies: BASF, Ludwigshafen, West Germany The Dow Chemical Company, Michigan, USA Dow Chemical Rheinwerk GmbH, Rheinmunster, West Germany ICI PLC, Runcorn, England S.

Download or read book Modeling Polymer colloid Phase Behavior written by Naa Larteokor Quarcoo and published by . This book was released on 2007 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, we investigate the phase behavior of silica colloids in solution with two uncharged polymers, polyethylene oxide (PEO) and polyvinylpyrrolidone (PVP), with the values of Rg/R = 0.7 and 1.8 for each polymer. The four observed phase boundaries are related to the polymer characteristics of Rg and entanglement concentration (c*). The polymer properties were characterized by viscometry, light scattering and size exclusion chromatography. The experimental observations suggest that phase separation depends on the ratio of the polymer concentration to the entanglement concentration for a given polymer.

Download or read book Clay Swelling and Colloid Stability written by Martin V. Smalley and published by CRC Press. This book was released on 2006-03-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a rare, over-the-shoulder perspective of a leading scientist’s own breakthroughs, Clay Swelling and Colloid Stability puts emphasis on two significant paradigm shifts in colloid science that explain particle interactions for charged plates, stacks, suspensions, and pastes as well as spherical colloids. Martin Smalley first discusses the replacement of the DLVO theory with the Coulombic Attraction Theory to explain the existence, extent, and properties of the two-phase region of colloid stability. Using the n-butylammonium vermiculite system as his model clay system, the author clarifies the flaws of conventional theories and presents the experimental details that form the basis of his new theories. He provides rigorous derivations that place the new electrical theory for charged colloids on a firm foundation in statistical mechanics. The author illustrates why a new, quantitative bridging flocculation model for polymer-stabilized colloids must replace the depletion flocculation model. Smalley also examines the discovery of the "dressed macroion" structure of clay plates in solution, the structure of a bridging polymer, and the distribution of polymer segments, counterions, and water molecules in the interlayer region. Based on the author’s own research and 36 publications in the field, Clay Swelling and Colloid Stability isa self-contained and intellectually satisfying account of the revolutionary process leading to a universally sound, and increasingly applicable, theory of colloid stability.

Download or read book Colloid Chemistry II written by Markus Antonietti and published by Springer. This book was released on 2003-07-03 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past forty years,good-old fashioned colloid chemistry has undergone something of a revolution,transforming itself from little more than a collection of qualitative observations of the macroscopic behavior of some complex systems into a discipline with a solid theoretical foundation and a whole to- boxofnew chemical techniques. It can now boast a set of concepts which go a long way towards providing an understanding of the many strange and interesting behavior patterns exhibited by natural and artificial systems on the mesoscale. This second volume of“Topics in Current Chemistry”on Colloid Chemistry, focuses on supramolecular approaches and new approaches towards polymer colloids,also with strong emphasis on biological and biomedical applications. Again topics were chosen which are expected to have broader relevance and to be interesting to a more general readership. The volume opens with a contribution by C.M.Paleos in which new amp- philes are presented which not only self-assemble to micelles or vesicles but also possess the ability to show specific recognition of complementary H-bridge p- terns.Such structures might point a way to a rational addressing of surfaces and supramolecular structures by purely chemical means.
