Available in PDF, EPUB and Kindle. Book excerpt: The first four volumes of the series on 'Charged and Reactive Polymers' have been devoted to polymers in solution (Voh. I and II) or in gel and membrane forms (Vols. III and IV). In correlation with charges, other physical or chemical properties of macro molecules have been considered. Understanding of charge and hydrophobic effects is equally important for synthetic and biopolymers or their systems. Optically Active Polymers are related to problems of the same class, since optical activity is an inherent property of both natural macromolecules as well as a great variety of polymers synthesized in the Jast twenty years. Optical activity is a physical spectral property of chiral matter caused by asymmetrical configurations, conformations and structures which have no plane and no center of symmetry and consequently have two mirror image enantiomeric forms of inverse optical rotation. The racemic mixture of chiral enantiomers is optically inactive. The most common form of optical activity was first measured at a constant wavelength by the angle of rotation of linearly polarized light. More recently the measurements have been extended to the entire range of visible and attainable ultraviolet regions where electronic transitions are observed, giving rise to the ORD technique (Optical Rotatory Dispersion). The Cotton effects appear in the region of optically active absorption bands; outside of these bands the plain curve spectrum is also dependent on all the electronic transitions of the chromophores.

Download or read book Active Polymers written by Andreas Lendlein and published by Cambridge University Press. This book was released on 2014-06-05 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of polymer research is progressing rapidly from passive materials providing a certain set of properties to active polymers, which provide, receive and respond to signals from their environment. This includes interactions with molecules, biological systems and physical stimuli. Research in active polymers has been driven by an increasing demand for intelligent materials, especially in biomedical and aerospace applications. Progress in synthesis, analytics and molecular modeling enable scientists to develop active polymer systems in a knowledge-based approach. Biological systems might serve as blueprints for biomimetic and bionic solutions, leading to innovative materials concepts. Emerging active polymers respond to a range of stimuli, from changes in pH and temperature, to light and magnetic fields. Remote and on-demand control is also envisioned. Contributors discuss shape-memory polymers; shape-changing polymers; responsive hydrogels; stimuli-sensitive systems; intelligent polymers in biological systems; polymer-based actuators, sensors, and switches; active surfaces; and biomedical applications of active materials, especially for tissue regeneration and controlled drug release.

This book was released on 1993-05-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroactive polymers have been the object of increasing academic and industrial interest and in the past ten to fifteen years substantial progress has been achieved in the development and the characterization of this important new class of conducting materials. These materials are usually classified in two large groups, according to the mode of their electric transport. One group includes polymers having transport almost exclusively of the ionic type and they are often called 'polymer electrolytes' or, in a broader way, 'polymer ionics'. The other group includes polymeric materials where the transport mechanism is mainly electronic in nature and which are commonly termed 'conducting polymers'. Ionically conducting polymers or polymer ionics may be typically described as polar macromolecular solids in which one or more of a wide range of salts has been dissolved. The most classic example is the combina tion of poly(ethylene oxide), PEO, and lithium salts, LiX. These PEO-LiX polymer ionics were first described and proposed for applications just over ten years ago. The practical relevance of these new materials was im mediately recognized and in the course of a few years the field expanded tremendously with the involvement of many academic and industrial lab oratories. Following this diversified research activity, the ionic transport mechanism in polymer ionics was soon established and this has led to the development of new host polymers of various types, new salts and advanced polymer architectures which have enabled room temperature conductivity to be raised by several orders of magnitude.

Download or read book Preparation and Properties of Stereoregular Polymers written by R.W. Lenz and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the texts of the main lectures presented at the NATO Advanced Studies Institute on "Advances in Preparation and Properties of Stereoregular Polymers" held at Tirrenia near Pisa, Italy, from October 3 to 14, 1978. A few contributed papers have also been included because they were concerned with topics not included in the main lectures. The primary objective of the Institute was to assist in the further development of stereoregular polymers because of the ever-increasing demand for new products with exceptional chemical and physical properties. This need has reawakened interest in the field. Indeed there is now a rapidly increasing activity in the study of stereoregular polymerization and the preparation of structurally-ordered polymers with the aim of achieving apprecia ble improvements in existing polymeric materials through new developments in synthesis and properties as well as in discovering new polymeric structures. In order to achieve these objectives, a broad interdiscipli nary cooperation among scientists involved in investigations on the design, synthesis, characterization and application of stereo regular or structurally-ordered polymers will be necessary.
