Available in PDF, EPUB and Kindle. Book excerpt: Polymer network based gels are an important class of materials with a wide range of applications. Dynamic polymer networks, which crosslink via the formation of reversible bonds, in particular have great potential as stimuli responsive, mechanically tunable, and self-healing materials. Many important emergent properties of these materials, such as mechanical strength, are mediated by their underlying network structure, which can be characterized by the network topology and spatial distribution of nodes. Therefore, unlocking the full potential of these materials through rational design requires an understanding of how network structure arises as a function of network-forming precursor design. Because the bonds that crosslink dynamic polymer networks are reversible, stresses initially present or otherwise induced in these systems can be relieved through network rearrangement. As such, given sufficient time to relax, the network structure is determined by equilibrium thermodynamics. This work presents a thermodynamic formalism which characterizes the free energy of a network in terms of node positional, network topological, and polymer conformational entropies. Through this lens, and aided by numerical calculations and simulations of model networks, we show how the free energy landscape with respect to density relates to factors which can be readily controlled through precursor design, such as polymer length and node size. Additionally, Monte Carlo simulations of explicit networks reveal that thermodynamic relaxation can give rise to spatial heterogeneity in the arrangement of network nodes. In the last chapter we use the tools developed in the earlier chapters to explore how these same design parameters influence the topological statistics of equilibrium networks. In addition to showing how internode connectivity increases with polymer length and system density, we find that inhomogeneity due to spatial relaxation can also lead to greater network connectivity. Finally, we explore the weakening of network topologies due to substitution of polymer-linked node forming components with topologically non-functional counterparts, finding that larger nodes fare better than their smaller counterparts in maintaining network connectivity when these substitutions are made.

The emphasis throughout the text is on understanding basic concepts and developing problem-solving skills. The mathematical difficulty increases gradually by chapter, but no calculus is required. Topics covered include energy and its transformation, the First Law of Thermodynamics, Gibbs free energy, statistical thermodynamics, binding equilibria and reaction kinetics. Each chapter comprises numerous illustrative examples taken from different areas of biochemistry, as well as a broad range of exercises and references for further study.
Download or read book Thermodynamics of Systems Containing Flexible Chain Polymers written by V.J. Klenin and published by Elsevier. This book was released on 1999-06-03 with total page 851 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the problems of the thermodynamics of systems containing flexible-chain polymers as the basis of polymer material science. The main thermodynamic quantities and concepts are introduced and discussed in the order of the objects getting more and more complicated: gases, magnets, low-molecular-weight substances and mixtures, and finally, polymers and polymer blends. All topics are considered in a common clue, using the principle of universality. The stability conditions for the one-phase state of multi-component systems are given. Phase separation is regarded as a result of loss in stability. The critical state of a system, with the one-phase state being close to the boundary of stability conditions breaking, is discussed in detail. The effects of both light scattering (elastic and dynamic) and diffusion, as directly depending on the thermodynamic parameters characterizing the one-phase state stability, are considered in detail. One of the versions of colloid scattering, namely, the turbidity spectrum method, is described as useful for the characterization of various heterogeneous structures and for the phase analysis of polymer systems. In the approximation of mean field theories and advanced field theory, formalisms expound the following divisions of the thermodynamics of binary and polynary systems with flexible-chain polymers: conformation of the polymer coil, composition fluctuations, elastic and dynamic light scattering, diffusion in the one-phase state (including the critical range), phase separation, polymer fractionation, the coil-globule transition, phase equilibrium and separation in the system network polymer + low-molecular-weight liquid, polymer blends and multiphase separation.

Available in PDF, EPUB and Kindle. Book excerpt: This major reference work, covering the important materials science area of gels, is a translation of a Japanese handbook. The three-volume set is organized to cover the following: fundamentals, functions, and environmental issues. Gels Handbook also contains an appendix, complete references, and data on gel compounds.Recently, polymer gels have attracted many scientific researchers, medical doctors, and pharmaceutical, chemical, and agricultural engineers to the rapidly growing field. Gels are considered to be one of the most promising materials in the 21st Century. They are unique in that they are soft, gentle, and can sense and accommodate environmental changes. Because of these unique characteristics gels have a huge potential in technological and medical applications. They are irreplaceable in the separation of molecules, the release of drugs, artificial skins and organs, sensors, actuators, chemical memories, and many other applications.The 21st century is also said to be the century of biotechnology, where two kinds of biopolymers play crucial roles: DNA as a bearer of geneticinformation and proteins as molecular machines. In spite of the dramatic progress in molecular biology and the Human Genome project, the basic principles behind the function and design of such polymeric machines are in the black box. Science and technologies that will emerge from those of polymer gels will shed light on such principles.Some researchers have already developed prototypes of artificial glands (pancreas), artificial muscles and actuators, and chemical sensors and molecular recovery systems using polymer gels.The Gels Handbook is an invaluable source of information on this rapidly growing field. It covers the entire area from the scientific basics to the applications of the materials. The authors are among the leading researchers, doctors, engineers, and patent officers in Japan. This book can be used as a textbook or an encyclopedia and is a must for those involved in gel research or applications.
