Download or read book Non Destructive Characterization of Polymer Interphases and In Situ Polymerization Using Surface Enhanced Raman Scattering written by and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular structure of interphases between substrates such as metals and graphite and polymer systems cured against them was determined using surface analysis techniques such as reflection-absorption infrared spectroscopy, X-ray photoelectron spectroscopy, and surface enhanced Raman scattering. It was found that the substrates had a significant effect on the molecular structure of the interphase and that the molecular structure of the interphase was significantly different from that of the bulk polymers. In some cases, there was a vigorous reaction between components of the polymer system and the substrate. Thus, when an acrylic adhesive was cured against silver substrates, o-benzoic sulfimide, a component of the curing system, segregated to the interface and reacted with metal ions to form salts. The salts reacted with a peroxide in the curing system to form radicals which initiated polymerization. In other cases, components of the polymer preferentially adsorbed onto the substrate. Thus the curing agent dicyandiamide was adsorbed at the interface between an epoxy and silver. The behavior of polyamic acids was strongly affected by substrates they were deposited on.

Download or read book Polymer Characterization Interdisciplinary Approaches written by Clara D. Craver and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical and spectroscopic methods have been used jointly for characterization of polymers for at least four decades. Yet, new techniques permit increasingly refined determination of polymer chemistry and morphol ogy_ The correlation of this knowledge with physical properties of polymers is helpful to planned synthesis of new products. The most prominent spectroscopic techniques through the forties and fifties were infrared and ultraviolet spectroscopy. Nuclear magnetic resonance, electron spin resonance and MOssbauer spectroscopy started making sig nificant contributions to polymer chemistry in the early sixties. Still more recently fluorescence spectroscopy and laser Raman spectroscopy have become readily appli cable to polymers and are contributing significantly to the understanding of the relationship between polymer structure and properties. Determination of the distribution of monomer se quences by molecular size has become possible through combined gel permeation chromatography and spectroscopic analysis. Fragments of polymers from chemical break down or from pyrolysis are further fractionated and structurally analyzed. The relationship between the chemistry of polymers and performance can be determined from changes in chemical structure and orientation after curing, degradation, or physical or thermal manipulation of the polymers.

Available in PDF, EPUB and Kindle. Book excerpt: This proceedings book presents the main findings of the 13th International Seminar on Polymer Science and Technology ( ISPST 2018), which was held at Amirkabir University of Technology, Tehran, on November 10–22, 2018. This forum was the culmination of more than three decades of academic and industrial activities of Iranian scholars and professionals, and the participation of many notable international scientists, in covering various important polymer-related subjects of concern to Iran and the world at large, including polymer synthesis, processing and properties, as well as issues concerning polymer degradation, stability, and environmental aspects. For the past half a century, the growing concern for advancing human health, quality of life, and – especially in the last few decades – avoiding and combating environmental pollution have shaped and driven scientific activities geared toward the creation of smart materials that are compatible with the human body, and have prompted scientists and technologists to pursue research using natural and sustainable sources. This book highlights efforts to responsibly address the problems caused by, and which can potentially be solved by, polymers and plastics.

This book was released on 1989 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: To optimize the properties of polymers or to design new polymeric materials for special applications, one has to understand how their properties depend on chemical and physical structure. This, in turn, requires methods for material characterization operating on a microscopic level such as optical techniques. Over the past decades major progress has been made in exploiting the analytical power offered by spectroscopic methods if combined with modern light source and detection technology. This multi-author book has been written in order to acquaint a broader audience with these recent achievements. Its individual chapters have been arranged in three groups featuring absorption, luminescence and diffraction techniques including non-linear optics for probing the physical structure of polymers, as well as their dynamic behavior in the presence and absence of electronic excitation. Emphasis has been placed on recent developments in the spectroscopy of solid polymers.

This book was released on 2014-06-21 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis offers novel insights into the time-dependent structural evolution of polymers under deformation. In-situ tensile experiments at high-brilliance synchrotron sources allowed to characterize the material with unrivaled resolution in time and space. The strain-induced crystallization in natural rubber was studied by wide-angle X-ray diffraction. Special emphasis was put on the establishment of new structure-property relationships to give a more in-depth understanding of the mechanical performance of rubber parts, e.g. in tear fatigue loading. To this end, the kinetics of strain-induced crystallization were investigated, subjecting the material to high strain rates. The local structure around a crack tip was observed by scanning wide-angle X-ray diffraction. Ultra-small angle X-ray scattering served to study filled elastomers under deformation, from specially prepared model filler systems to industrially relevant carbon black filled rubbers. Other methods include electron microscopy coupled with in-situ tensile testing and optical dilatometry to examine cavitation in rubbers. The underlying theory as well as a literature review are covered by an extensive introductory chapter, followed by a description of the experimental techniques. The results are presented in more detail than in the original journal publications.

Available in PDF, EPUB and Kindle. Book excerpt: Polymers are an important class of materials with a broad spectrum of mechanical properties that warrant their utility in various applications. Modern polymer characterization techniques have been valuable in providing multiscale insight into the structure and properties, including molecular structure and morphology, and thermal and mechanical properties, respectively. However, these techniques have been performed postmortem or have limitations that are unsuitable for in-situ characterization. The latter hinders the complete understanding of dynamic mechanical responses in polymers and the corresponding fundamental molecular mechanisms. Therefore, this research aims to develop a novel experimental solid mechanics setup capable of loading elastomeric polymers at various strain rates while concurrently interrogating the sample with a bulk spectroscopic technique using terahertz waves. The resulting time and frequency domains data and the supporting micrographs, computational and analytical solutions, digital image correlation, and light-matter interaction analyses substantiate the validity of utilizing terahertz-based spectroscopy to capture the underlying molecular mechanisms of mechanically loaded polymers. Furthermore, the fundamental insight gained through the in-situ spatiotemporal characterization of dynamically loaded polymers will accelerate the development of shock-tolerant and impact-resistant materials.
