Book excerpt: Cellulose Acetate: Properties, Uses and Preparation presents data on thermodynamic characteristics (heat capacity, enthalpy, entropy, and Gibbs function) from 4 to 580 K cellulose acetates and cellulose nitrates, as well as the major plasticizers for these polymers, the temperatures of their relaxation and phase transitions, the effect of plasticizers on these characteristics of cellulose acetate and cellulose nitrate and the solubility of plasticizers in polymers. Cellulose diacetate has been used in the design of sorption matrices for the fluorescent analysis of polyaromatic and heterocyclic compounds. Thus, the physicochemical properties of cellulose diacetate solutions in a binary acetone-water solvent were analyzed along with the morphological, surface-energy, physicochemical and physicomechanical characteristics of film matrices in comparison with fiber ones. Additionally, the authors examine how the growth of CO2 emissions efforts led to the necessity for green material solutions that fit into a sustainable development policy and low environmental impact. The major barriers to produce cellulose-based products from agricultural residues are the heterogeneity of the raw material, the experimental conditions reproducibility, the heterogeneous phase of the synthesis reaction, the difficulty of purification, the effluent disposal, and the control of the product quality. In the closing study, the authors provide a comprehensive review of electrospun nanofibres from different types of polymers with synthesized montmorillonite clays. Loading activated natural bentonite clay into any type of polymer can improve the adsorption property of electrospun nanofibres, but the bentonite clay must be well dispersed, suspended and loaded to achieve any benefit. This study may pave the way for further use of electrospun nanofibres loaded with clay in a wide variety of environmental and medical applications.

Download or read book Advanced Green Composites written by Anil N. Netravali and published by John Wiley & Sons. This book was released on 2018-10-04 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most composites, particularly those made using thermoset resins, cannot be recycled or reused. As a result, most of them end up in landfills at the end of their useful life which is neither sustainable nor environment-friendly. Various laws enacted by Governments around the world and heightened global awareness about sustainability and global warming is changing this situation. Significant research is being conducted in developing and utilizing sustainable fibers and resins, mostly derived from plant, to fabricate 'Green' composites. The significant progress in the past 20 or so years in this field has led to the development of green composites with high strength or so called Advanced Green Composites. More interestingly, green composites have also acquired various different properties such as fire resistance, transparency, barrier to gases and others. The term 'advanced' which only included high strength and stiffness now includes all these special properties. The world is on the cusp of a major change, and once fully developed, such composites could be used in applications ranging from automobiles to sporting goods, from circuit boards to housing and from furniture to packaging. This book, by presenting the state-of-the-art developments in many aspects of advanced green composites adds significantly to the knowledge base that is critical for their success of expanding their use in applications never seen before. The chapters are written by world’s leading researchers and present in-depth information in a simple way. This provides readers and researchers the latest developments in the field of 'Green' resins (with ways of strengthening them), High Strength Green Fibers (including micro and nano-cellulose fibrils/fibers) and Green Composites in the first few chapters. The introductory chapter summarizes the consequences of using conventional, petroleum-based materials and the need for green composites as well as the progress being made in this field. After that the book delves in to Advanced Green Composites in a broader sense and includes chapters on High Strength Green Composites, Self-healing Green Composites, Transparent Green Composites, All-cellulose composites, Toughened Green Composites, Green Biofoams, Bioinspired Shape Memory Composites, etc. The chapters are written by the experts who are highly respected in their fields.

Download or read book Infrared Spectra of Cellulose and its Derivatives written by R. G. Zhbankov and published by Springer. This book was released on 2013-12-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is concerned with systematization of the infrared spectra of an important natural polymer, cellulose, and its derivatives. The infrared spectra of the main classes of cellulose derivatives are de scribed and interpreted and those of such model compounds as mono-, di-, and trisaccharides are considered. Considerable attention is given to prob lems of technique in obtaining infrared spectra of fibrous cellulose materials, and to the analytical possibilities of infrared spectroscopy in studies of the properties of cellulose and its derivatives. The book will be of use to scientific and plant workers interested in the study and treatment of cellulose, compounds related to cellulose (carbo hydrates and polycarbohydrates), and other polymers. v INTRODUCTION Spectroscopy has nowadays acquired great scientific and practical im portance. Its possibilities are based on the specificity of the emission and ab sorption spectra of all types of material, from elements to complex natural products. Most widely used are the methods of emission spectral analysis (analysis of the emission spectrum from an incandescent body). The rapidity and availability of these methods, together with their high sensitivity and selectivity, has made them indispensable in the practice of plant and scien tific laboratories for establishing the presence of specific elements in a sub stance under investigation.

Download or read book Evaluation of Cellulose Ethers for Conservation written by Robert L. Feller and published by Getty Publications. This book was released on 1991-03-21 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of a three-year research program. It describes the chemical character of cellulose ethers as a general class of polymers and establishes an approximate ranking of the relative stability of each generic chemical subclass. Ranking the thermal stability of the polymers with respect to color change and loss in degree of polymerization led to the conclusion that as generic chemical classes, methylcellulose and carboxymethylcellulose appear to be the most stable of the cellulose ethers. Water-soluble ethylhydroxyethylcellulose apparently also possesses good stability. Of questionable long-term stability are hydroxyethylcellulose and hydroxy- propylcellulose. Ethylcellulose and organic-soluble ethylhydroxyethylcellulose proved to be of poor stability, potentially undergoing marked changes in twenty years or less under normal museum conditions. An important additional conclusion reached here, as well as in an earlier investigation, is that considerable variations in stability can occur within a generic chemical class from differences in the basic raw material, a natural product from plants, which is not a uniform, manufactured, chemical substance. Further variations can exist due to different manufacturing processes or commercial sources. Hence, commercial products must be evaluated individually to determine the most stable of a given generic type. Nonetheless, the authors believe the conclusions expressed here to be valid with regard to the relative stability of the generic chemical classes of cellulose ethers.
