Download or read book Polyampholytes written by Sarkyt E. Kudaibergenov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to adapt the properties of living materials to their biological functions, nature has developed unique polyelectrolytes with outstanding physical, chemical and mechanical behavior. Namely polyampholytes can be suitable substances to model protein folding phenomenon and enzymatic activity most of biological macromolecules due to the presence of acidic and basic groups. The ability of linear and crosslinked amphoteric macromolecules to adopt globular, coil, helix and stretched conformations and to demonstrate coil-globule, helix-coil phase transitions, and sol-gel, collapsed expanded volume changes in relation to internal (nature and distribution of acid and base substituents, copolymer composition, hydrophobicity etc. ) and external (pH, temperature, ionic strength of the solution, thermodynamic quality of solvents etc. ) factors is very important and constantly attracts the attention of theorists and experimentalists because the hierarchy of amphoteric macromolecules can repeat, more or less, the structural organization of proteins. That is why polyampholytes fall within eyeshot of several disciplines, at least polymer chemistry and physics, molecular biology, colloid chemistry, coordination chemistry and catalysis. The main purpose of this monograph is to bridge the gap between synthetic and natural polymers and to show a closer relationship between two fascinating worlds. The first chapter of the book acquaints the readers with synthetic strategy of "annealed", "quenched" and "zwitterionic" polyampholytes. Radical copolymerization, chemical modification and radiation-chemical polymerization methods are thoroughly considered. Kinetics and mechanism of formation of random, alternating, graft, di-block or tri-block sequences is discussed. The second chapter deals with behavior of polyampholytes in solutions.

Download or read book Self Healing Polymers written by Wolfgang H. Binder and published by John Wiley & Sons. This book was released on 2013-03-29 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-healing is a well-known phenomenon in nature: a broken bone merges after some time and if skin is damaged, the wound will stop bleeding and heals again. This concept can be mimicked in order to create polymeric materials with the ability to regenerate after they have suffered degradation or wear. Already realized applications are used in aerospace engineering, and current research in this fascinating field shows how different self-healing mechanisms proven successful by nature can be adapted to produce even more versatile materials. The book combines the knowledge of an international panel of experts in the field and provides the reader with chemical and physical concepts for self-healing polymers, including aspects of biomimetic processes of healing in nature. It shows how to design self-healing polymers and explains the dynamics in these systems. Different self-healing concepts such as encapsulated systems and supramolecular systems are detailed. Chapters on analysis and friction detection in self-healing polymers and on applications round off the book.
Download or read book Template Polymerization written by Stefan Polowinski and published by ChemTec Publishing. This book was released on 1997 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Template polymerization is a new field in polymer synthesis but common practice in the biosynthesis since DNA is the most popular template or matrix on which proteins are built by living species. This field is relevant to the synthesis of polymers of controlled structure but its application goes beyond the synthesis. Materials are formulated in complex mixtures always containing components which can be regarded as templates on which other materials are formed, modified, or are interacted with. In the new product development the relevance of these phenomena is controlled by the order of addition which affects probabilities and preferences of interaction. The current publication outlines mechanisms of template polymerization, polycondensation, and copolymerization. These mechanisms, illustrated with numerous examples, indicate a range of possibilities which can be encountered in materials and utilized to modify their properties. Orientation of substrates on template and their effect on modification of their reactivity and properties such as, for example, absorption of light or water are also discussed. Several chapters contain information on these studies discussed with sufficient detail to give reader comprehensive understanding of the methods used in various research laboratories and their findings."--Publisher's description.
