Book Synopsis Kinetics of Aggregation and Gelation by : F. Family
Download or read book Kinetics of Aggregation and Gelation written by F. Family and published by Elsevier. This book was released on 2012-12-02 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinetics of Aggregation and Gelation presents the proceedings of the International Topical Conference on Kinetics of Aggregation and Gelation held on April 2-4, 1984 in Athens, Georgia. The purpose of the conference was to bring together international experts from a wide variety of backgrounds who are studying phenomena inherently similar to the formation of large clusters by the union of many separate, small elements, to present and exchange ideas on new theories and results of experimental and computer simulations. This book is divided into 57 chapters, each of which represents an oral presentation that is part of a unified whole. The book begins with a presentation on fractal concepts in aggregation and gelation, followed by presentations on topics such as aggregative fractals called ""squigs""; multi-particle fractal aggregation; theory of fractal growth processes; self-similar structures; and interface dynamics. Other chapters cover addition polymerization and related models; the kinetic gelation model; a new model of linear polymers; red cell aggregation kinetics; the Potts Model; aggregation of colloidal silica; the ballistic model of aggregation; stochastic dynamics simulation of particle aggregation; particle-cluster aggregation; kinetic clustering of clusters; computer simulations of domain growth; and perspectives in the kinetics of aggregation and gelation. This book will be of interest to practitioners in the fields of chemistry, theoretical physics, and materials engineering.
Book Synopsis Aggregation and Gelation in Random Networks by : Stephan Ulrich
Download or read book Aggregation and Gelation in Random Networks written by Stephan Ulrich and published by Stephan Ulrich. This book was released on 2010-06-23 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the formation, elasticity, and structure of randomly cross-linked networks is investigated analytically and with the help of computer simulations. In the first two chapters, two polymer models are studied by means of equilibrium statistical mechanics and replica theory an isotropic model of randomly cross-linked particles and an anisotropic model of cross-linked directed polymers. For both models, a suitable order parameter describing the gelation transition is developed at first. With it, the elastic properties of the isotropic network is determined for arbitrary cross-link concentration and the extent of the chain fluctuations and the role of the preferred direction are studied for the anisotropic system. As a real life example, the structure of spider silk is analyzed, a material with very high toughness despite its low density. Here nano-crystallites are randomly connected by an amorphous network of chains. A model for the embedding of the crystallites in the amorphous matrix is developed, accounting for the crystallites' structure, arrangement, and their random orientation relative to the fiber axis. With this model, the scattering function S(q) of the crystallites can be calculated and compared to experimental scattering intensities enabling the determination of the geometric and statistical parameters. The rather general model for nano-crystalline materials can also be used to determine the importance of disorder and coherent scattering between different crystallites, which is usually neglected for wide angle X-ray scattering.Random networks of capillary bridges can occur in wet sand. By adding a small amount of a liquid to a granular system, the particles can create liquid capillary bridges between each other. When such a bridge ruptures, a fixed amount of energy is dissipated different from the ordinary granular interaction where a fraction of the kinetic energy is dissipated in a collision. A freely cooling system is shown to undergo a nonequilibrium dynamic phase transition from a state with mainly single particles and fast cooling to a state with growing aggregates, where bridge rupture becomes a rare event and cooling is slow. Initially, the aggregation of particles into clusters is a self-similar growth process, where fractal objects are generated and with a cluster size distribution that can be described by a scaling function. At later times a percolating cluster is found, which gradually absorbs all other particles.

Book Synopsis Synthesis, Characterization, and Theory of Polymeric Networks and Gels by : Shaul M. Aharoni
Download or read book Synthesis, Characterization, and Theory of Polymeric Networks and Gels written by Shaul M. Aharoni and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer science is a technology-driven science. More often than not, technological breakthroughs opened the gates to rapid fundamental and theoretical advances, dramatically broadening the understanding of experimental observations, and expanding the science itself. Some of the breakthroughs involved the creation of new materials. Among these one may enumerate the vulcanization of natural rubber, the derivatization of cellulose, the giant advances right before and during World War II in the preparation and characterization of synthetic elastomers and semi crystalline polymers such as polyesters and polyamides, the subsequent creation of aromatic high-temperature resistant amorphous and semi-crystal line polymers, and the more recent development of liquid-crystalline polymers mostly with n~in-chain mesogenicity. other breakthroughs involve the development of powerful characterization techniques. Among the recent ones, the photon correlation spectroscopy owes its success to the advent of laser technology, small angle neutron scattering evolved from n~clear reactors technology, and modern solid-state nuclear magnetic resonance spectroscopy exists because of advances in superconductivity. The growing need for high modulus, high-temperature resistant polymers is opening at present a new technology, that of more or less rigid networks. The use of such networks is rapidly growing in applications where they are used as such or where they serve as matrices for fibers or other load bearing elements. The rigid networks are largely aromatic. Many of them are prepared from multifunctional wholly or almost-wholly aromatic kernels, while others contain large amount of stiff difunctional residus leading to the presence of many main-chain "liquid-crystalline" segments in the "infinite" network.

Book Synopsis Grafting/Characterization Techniques/Kinetic Modeling by :
Download or read book Grafting/Characterization Techniques/Kinetic Modeling written by and published by Springer. This book was released on 2007-10-13 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the untreated surfaces of polymers used in industry are not hydrophilic but hydrophobic. It is, therefore, difficult to bond these nonpolar polymer sur faces directly to other substances like adhesives, printing inks, and paints because they generally consist of polar compounds. On the other hand, polymer surfaces generally adsorb proteins when brought into direct contact with a bio logical system, resulting in cell attachment or platelet aggregation. The protein adsorption and attachment of biological components trigger a subsequent series of mostly adverse biological reactions toward the polymeric materials. Therefore, the technologies for surface modification of polymers or regulation of the polymer surface interaction with other substances have been of prime importance in polymer applications from the advent of polymer industries. Some of the technologies have been directed to introduction of new function alities onto polymer surfaces. The new functionalities introduced include improved surface hydrophilicity, hydrophobicity, bio compatibility, conductivi ty, anti-fogging, anti-fouling, grazing, surface hardness, surface roughness, adhesion, lubrication, and antistatic property. Theoretically, there is a large dif ference in properties between the surface and the bulk of a material and only the outermost surface is enough to be taken into consideration when the sur face properties are concerned. However, this is not the case for polymer surfaces, as the physical structure of the outermost polymer surface is generally not fixed but continuously changing with time due to the microscopic Brownian motion of polymer segments.
