Book Description
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.

Book Description
The field of bio-based plastics has developed significantly in the last 10 years and there is increasing pressure on industries to shift existing materials production from petrochemicals to renewables. Bio-based Plastics presents an up-to-date overview of the basic and applied aspects of bioplastics, focusing primarily on thermoplastic polymers for material use. Emphasizing materials currently in use or with significant potential for future applications, this book looks at the most important biopolymer classes such as polysaccharides, lignin, proteins and polyhydroxyalkanoates as raw materials for bio-based plastics, as well as materials derived from bio-based monomers like lipids, poly(lactic acid), polyesters, polyamides and polyolefines. Detailed consideration is also given to the market and availability of renewable raw materials, the importance of bio-based content and the aspect of biodegradability. Topics covered include: Starch Cellulose and cellulose acetate Materials based on chitin and chitosan Lignin matrix composites from natural resources Polyhydroxyalkanoates Poly(lactic acid) Polyesters, Polyamides and Polyolefins from biomass derived monomers Protein-based plastics Bio-based Plastics is a valuable resource for academic and industrial researchers who are interested in new materials, renewable resources, sustainability and polymerization technology. It will also prove useful for advanced students interested in the development of bio-based products and materials, green and sustainable chemistry, polymer chemistry and materials science.

Book Description
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.
