Available in PDF, EPUB and Kindle. Book excerpt: Control of polymeric structure is among the most important endeavours of modern macromolecular science. In particular, tailoring the positioning and strength of intermolecular forces within macromolecules by synthetic methods and thus gaining structural control over the final polymeric materials has become feasible, resulting in the field of supramolecular polymer science. Besides other intermolecular forces, hydrogen bonds are unique intermolecular forces enabling the tuning of material properties via self-assembly processes over a wide range of interactions strength ranging from several kJmol to several tens of kJmol . Central for the formation of these structures are precursor molecules of small molecular weight (usually lower than 10 000), which can assemble in solid or solution to aggregates of defined geometry.

This book was released on 2023-01-27 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural polymers have always been used in medicine. However, the development of synthetic polymers for use in medicine has occurred only in the last few decades. The successful applications of these synthetic polymers in medicine depend mainly on their physico-chemical and special characteristics such as biological compatibility with tissues, stability, durability and elasticity. This book deals mainly with the kinetic and structural aspects which are essential for the realization of these characteristics. The authors have examined in detail the processes of diffusion, chemical and biological diintegration, changes in various structural levels induced by chemical and biological media, and the problems of simultaneous influence of these media and mechanical strains on polymers used in medicine. Researchers in the field of polymer physics and chemistry, as well as those who are working with applications of polymers in medicine and biology should find this book useful.

Book excerpt: The progress in polymer science is revealed in the chapters of Polymer Science: A Comprehensive Reference, Ten Volume Set. In Volume 1, this is reflected in the improved understanding of the properties of polymers in solution, in bulk and in confined situations such as in thin films. Volume 2 addresses new characterization techniques, such as high resolution optical microscopy, scanning probe microscopy and other procedures for surface and interface characterization. Volume 3 presents the great progress achieved in precise synthetic polymerization techniques for vinyl monomers to control macromolecular architecture: the development of metallocene and post-metallocene catalysis for olefin polymerization, new ionic polymerization procedures, and atom transfer radical polymerization, nitroxide mediated polymerization, and reversible addition-fragmentation chain transfer systems as the most often used controlled/living radical polymerization methods. Volume 4 is devoted to kinetics, mechanisms and applications of ring opening polymerization of heterocyclic monomers and cycloolefins (ROMP), as well as to various less common polymerization techniques. Polycondensation and non-chain polymerizations, including dendrimer synthesis and various "click" procedures, are covered in Volume 5. Volume 6 focuses on several aspects of controlled macromolecular architectures and soft nano-objects including hybrids and bioconjugates. Many of the achievements would have not been possible without new characterization techniques like AFM that allowed direct imaging of single molecules and nano-objects with a precision available only recently. An entirely new aspect in polymer science is based on the combination of bottom-up methods such as polymer synthesis and molecularly programmed self-assembly with top-down structuring such as lithography and surface templating, as presented in Volume 7. It encompasses polymer and nanoparticle assembly in bulk and under confined conditions or influenced by an external field, including thin films, inorganic-organic hybrids, or nanofibers. Volume 8 expands these concepts focusing on applications in advanced technologies, e.g. in electronic industry and centers on combination with top down approach and functional properties like conductivity. Another type of functionality that is of rapidly increasing importance in polymer science is introduced in volume 9. It deals with various aspects of polymers in biology and medicine, including the response of living cells and tissue to the contact with biofunctional particles and surfaces. The last volume is devoted to the scope and potential provided by environmentally benign and green polymers, as well as energy-related polymers. They discuss new technologies needed for a sustainable economy in our world of limited resources. Provides broad and in-depth coverage of all aspects of polymer science from synthesis/polymerization, properties, and characterization methods and techniques to nanostructures, sustainability and energy, and biomedical uses of polymers Provides a definitive source for those entering or researching in this area by integrating the multidisciplinary aspects of the science into one unique, up-to-date reference work Electronic version has complete cross-referencing and multi-media components Volume editors are world experts in their field (including a Nobel Prize winner)

Download or read book Solution Self Assembly of Sequence Specific Biomimetic Polymers written by Hannah Murnen and published by . This book was released on 2012 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological molecules, such as polypeptides, form the basis for most of life's functions. These simple linear polymers made up of only 20 amino acids can fold to form complex and intricate structures that span several length scales. The structures that arise from these molecules stem from their high level of molecular control. Each molecule is an exact sequence with complete monodispersity. From this angstrom level of control, micron scale structures can be assembled. This process is one of the most studied in the history of science, but due to the diversity of amino acids and potential interactions, it is still nearly impossible for scientists to look at a peptide sequence and predict a folded structure. Likewise, it is very difficult to choose a desired structure for a particular function and reverse engineer the linear sequence that will provide that structure. Therefore, there is the need for simplified systems to understand the interactions involved in protein folding and to begin to build the knowledge necessary for engineering similar types of functional structures. This thesis uses sequence specific biomimetic polymers, namely polypeptoids or poly N-substituted glycines, to fundamentally probe the chain conformation and assembly properties of sequence specific polymers. Polypeptoids or N-substituted glycines, are sequence specific biomimetic chains that have the same backbone as polypeptides. However, rather than the side chain being attached through the alpha carbon, it is attached to the backbone nitrogen. This chemical alteration has several implications for the system including the elimination of backbone hydrogen bonding and chirality. This chemical alteration yields a more flexible and tunable chain where intramolecular interactions can be modulated by the introduction of different side chains. In addition, the synthesis of polypeptoids is a simple two step submonomer addition that uses a primary amine as the submonomer. This results in a very high yield synthesis with virtually limitless possibilities for side chains due to the commercial availability of a wide variety of primary amines. Using this modular system, my thesis focuses on understanding the solution self assembly of a sequence specific biomimetic polymer. Much of the work has focused on understanding the single chain conformation and collapse of polypeptoids in order to apply this information to larger self assembly systems. The persistence lengths of several polypeptoids have been measured including those containing secondary structure or ionic groups in order to understand the effect of these factors on the chain conformation. Additionally, the collapse or folding of a single polypeptoid chain into a globule structure is discussed. The impact of monomer sequence on this collapse was investigated and shown to have an important effect both on the coil to globule transition as well as the resulting globule structure. Finally, a hierarchical super helix formed through the assembly of an amphiphilic diblock copolypeptoid is discussed. Using chemical modifications coupled with x-ray scattering, the super structure was shown to include ordering stemming from the angstrom level packing of molecules all the way up to the micron scale diameter of the helix.
