Advances in polymer nanocomposite technology   Publication : [S.l.] Nova Science Pub Inc 2010 . 445 p. , Polymer nanocomposites have revolutionised the research effort in the field of composites as they lead to the achievement of synergistic effects from the organic and inorganic components of the system and have led to the expansion of the spectrum of application of the commodity polymers to more advanced high end applications. Although a number of successful systems could be achieved, the inorganic filler still could not be optimally dispersed on nanometer scale in non polar polymers. Also, the thermal degradation of the surface modification of the inorganic component disturbs the organic inorganic phase compatibility and hence the resulting composite properties. In recent years, many new techniques have been employed to overcome these problems which include more advanced modification protocols of the inorganic filler, development of more thermally stable surface modification and altogether new synthesis technologies for polyolefin nanocomposites. There has also been a constant need to compare the composite properties with the property models and hence to be able to predict the properties of the similar systems in advance. However, until now, the conventional models developed for conventional micro composites were used, which in no way maps the nanocomposite systems. The recently developed statistical as well as finite element methods focusing the real nanocomposite morphologies have been more helpful for this purpose. Though a tremendous research focus lies on these polymer systems, there is also a need to give some attention to more environmentally friendly nanocomposite systems and to develop methods to achieve proper recycling. 26 cm.

Handbook of carbohydrate polymers development, properties and applications   Publication : New York Nova Science Pub Inc 2010 . 864 p. , Carbohydrates play an important role in many biological and biochemical processes, including the fertilisation, cell differentiation and maturation, protein folding and degradation. Carbohydrate polymers covers the study and exploitation of carbohydrate polymers which have current or potential industrial application in areas such as food, textiles, paper, wood, adhesives, biodegradables, biorefining, pharmaceuticals, and oil recovery. This book focuses on recent developments on carbohydrate-binding module (CBM) applications in the biomedical, biological and biotechnological fields. Furthermore, polysaccharides are complex carbohydrates that are made up chains of monosaccharide units linked by glycosidic bonds. This book reviews the literature on fibres spun from several polysaccharides and fibre spinning techniques, including both conventional fibre spinning methods and electrospinning. Resulting fibre properties and prospective applications are discussed. This book also reviews research on polysaccharide film-formation and characteristics, analysed mechanical and barrier properties of polysaccharide-based films, summarises applications of polysaccharide films in food products and makes conclusions as to the status of polysaccharide films and their future developmental direction. Other chapters in this book examine the pathways leading to the production of bioactive oligosaccharides that have biotechnological applications. The current progress in the development of marine carbohydrates into nutraceuticals and their applications are explored as well. 27 cm.
