This book was released on 2020 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionic polymers have capabilities to shape the pathway to new membranes and polymer systems that did not exist before. The imidazolium moiety has shown substantial abilities to integrate into a platform for ionic polymers allowing their growth and formation through imidazolium use as a building block. Addition of this component, both ionic and non-ionic, into a polymer matrix has been developed, but the creation of highly tunable, modular polymer structure that contains imidazolium has the potential to surpass previous iterations of ionic compounds and materials in gas separation. After developing a tailorable approach to high performance ionic polymers, we have formed ionic polyimides and polyamides that have been used for various applications such as gas separation, coatings, and films. The ionic polyimides and polyamides which were formed have the potential to be used as CO2/light gas membranes.The hardest factor to overcome within membrane separation is the flux-selectivity tradeoff which describes the upper limits of permeability, gases ability to flow through a membrane, and selectivity, one gas's ability over another to permeate. With the addition of these ionic units into the backbone and as "free"-ILs within the polymer matrix, the permeabilities of these materials can be greatly increased. Through systematic design and study of materials, the structure-property relationship of these newly developed ionic polymers can be determined and applied to further the understanding of these unique polymer systems.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation details the development and performance of a library of imidazolium ionenes for advanced engineering applications, with an emphasis on membrane-based gas separations and additive manufacturing. Several distinct sets of high-performance ionenes, polymers which contain ionic groups along the backbone chain rather than as pendants, were methodically designed and synthesized. These materials combine structural features commonly associated with state-of-the-art gas-separation membranes with chemical functionalities associated with high-performance engineering polymers. These functional features are spaced by incorporated ionic groups along the main chain, specifically imidazolium cations paired with fluorinated, delocalized anions. The modular synthetic methods and diverse processability of these new ionenes demonstrate that the rational design of materials can lead to enhanced performance and unique properties and behaviors. Through variation of substituents, connectivity along the backbone, and the sequence of functional and ionic segments, this work demonstrates the expansive opportunities for incorporating, distributing, and alternating structural features. These ionenes possess excellent thermal and mechanical properties, while the tailorability and synthetic modularity ionenes provide access to an array of interesting behaviors and molecular architectures. These ionic polymers materials exhibit self-assembly and local structuring when impregnated with free imidazolium-based ionic liquids (IL) or multivalent organic salts, which contributes additional tunability and alters intermolecular interactions in the ionene matrix. These HP-ionenes and IL composites were thoroughly characterized to develop structure-property relationships and to understand the coordination between the dispersed, discrete additives and the polymeric ionene matrix. Using the information gathered from characterization of these ionenes and IL composites, the specific suitability of processing techniques for each series of functional imidazolium ionenes was explored, yielding applied studies of these advanced materials as films/coatings, fibers, 3D printing resins, and self-healing elastomers.

Available in PDF, EPUB and Kindle. Book excerpt: Clay–Polymer Nanocomposites is a complete summary of the existing knowledge on this topic, from the basic concepts of synthesis and design to their applications in timely topics such as high-performance composites, environment, and energy issues. This book covers many aspects of synthesis such as in- situ polymerization within the interlamellar spacing of the clays or by reaction of pristine or pre-modified clays with reactive polymers and prepolymers. Indeed, nanocomposites can be prepared at industrial scale by melt mixing. Regardless the synthesis method, much is said in this book about the importance of theclay pre-modification step, which is demonstrated to be effective, on many occasions, in obtaining exfoliated nanocomposites. Clay–Polymer Nanocomposites reports the background to numerous characterization methods including solid state NMR, neutron scattering, diffraction and vibrational techniques as well as surface analytical methods, namely XPS, inverse gas chromatography and nitrogen adsorption to probe surface composition, wetting and textural/structural properties. Although not described in dedicated chapters, numerous X-ray diffraction patterns of clay–polymer nanocomposites and reference materials are displayed to account for the effects of intercalation and exfoliations of layered aluminosilicates. Finally, multiscale molecular simulation protocols are presenting for predicting morphologies and properties of nanostructured polymer systems with industrial relevance. As far as applications are concerned, Clay–Polymer Nanocomposites examines structural composites such as clay–epoxy and clay–biopolymers, the use of clay–polymer nanocomposites as reactive nanocomposite fillers, catalytic clay-(conductive) polymers and similar nanocomposites for the uptake of hazardous compounds or for controlled drug release, antibacterial applications, energy storage, and more. The most comprehensive coverage of the state of the art in clay–polymer nanocomposites, from synthesis and design to opportunities and applications Covers the various methods of characterization of clay–polymer nanocomposites - including spectroscopy, thermal analyses, and X-ray diffraction Includes a discussion of a range of application areas, including biomedicine, energy storage, biofouling resistance, and more

Download or read book Compendium of Polymer Terminology and Nomenclature written by Richard G Jones and published by Royal Society of Chemistry. This book was released on 2009-01-19 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUPAC system of polymer nomenclature has aided the generation of unambiguous names that re ect the historical development of chemistry. However, the explosion in the circulation of information and the globalization of human activities mean that it is now necessary to have a common language for use in legal situations, patents, export-import regulations, and environmental health and safety information. Rather than recommending a ‘unique name’ for each structure, rules have been developed for assigning ‘preferred IUPAC names’, while continuing to allow alternatives in order to preserve the diversity and adaptability of nomenclature. Compendium of Polymer Terminology and Nomenclature is the only publication to collect the most important work on this subject into a single volume. It serves as a handy compendium for scientists and removes the need for time consuming literature searches. One of a series issued by the International Union of Pure and Applied Chemistry (IUPAC), it covers the terminology used in many and varied aspects of polymer science as well as the nomenclature of several di erent types of polymer including regular and irregular single-strand organic polymers, copolymers and regular double-strand (ladder and spiro) organic polymers.

Book excerpt: Polyimide is one of the most efficient polymers in many industries for its excellent thermal, electrical, mechanical, and chemical properties as well as its easy processability. In the electronic and electrical engineering industries, polyimide has widely been used for decades thanks to its very good dielectric and insulating properties at the high electric field and at high temperatures of around 200°C in long term-service. Moreover, polyimide appears essential for the development of new electronic devices where further considerations such as high power density, integration, higher temperature, thermal conduction management, energy storage, reliability, or flexibility are required in order to sustain the growing global electrical energy consumption. This book gathers interdisciplinary chapters on polyimide in various topics through state-of-the-art and original ongoing research.
