Natural fiber composites have experienced a renaissance over the last two decades as a response to societal demands for developing eco-friendly, biodegradable and recyclable materials. They are now being extensively used in everyday products as well as in automotive, packaging, sports and the construction industries. These fibers require surface treatments in order to improve their properties and interfacial bonding with polymer matrices, and to reduce their hydrophilic character. These methods can be grouped into three major categories: chemical, physical and biological. Chemical methods use chemical reagents to reduce fibers' hydrophilic tendency and thus improve compatibility with the matrix. They also expose more reactive groups on the fibre surface to facilitate efficient coupling with the matrix. Physical methods change structural and surface properties of the fiber and thereby influence the interfacial bonding with matrices, without extensively changing the chemical composition of the fibers. They are cleaner and simpler than the chemical methods. Biological methods use biological agents like fungi, enzymes and bacteria to modify the fiber surface properties. These methods are not toxic like chemical methods and are not energy-intensive like physical methods. Surface Treatment Methods of Natural Fibers and their Effects on Biocomposites presents an overview and recent developments of these methods. All the major methods are reviewed, explaining the science and methodology behind each method. The effects of these methods on various properties of fibers and the biocomposites made from these fibers are analyzed in detail. Current applications of these methods in various industries are also reviewed. The book will be an essential reference for academic researchers, materials scientists and engineers, postgraduate students and industrial researchers and development scientists and engineers working on natural fibers and biocomposites. Extensive coverage of all the surface modification methods (chemical, physical, biological) of natural fibers and its effect on properties of produced composites The chemical mechanisms which are utilized in surface treatments are discussed in detail and how these affect the interfacial properties and characteristics Systematic and comprehensive review on surface modifications of natural fibres, and explains how the effect of the surface treatment can be characterized and measured, as well as the effect on properties

Polymer composites are materials in which the matrix polymer is reinforced with organic/inorganic fillers of a definite size and shape, leading to enhanced performance of the resultant composite. These materials find a wide number of applications in such diverse fields as geotextiles, building, electronics, medical, packaging, and automobiles. This first systematic reference on the topic emphasizes the characteristics and dimension of this reinforcement. The authors are leading researchers in the field from academia, government, industry, as well as private research institutions across the globe, and adopt a practical approach here, covering such aspects as the preparation, characterization, properties and theory of polymer composites. The book begins by discussing the state of the art, new challenges, and opportunities of various polymer composite systems. Interfacial characterization of the composites is discussed in detail, as is the macro- and micromechanics of the composites. Structure-property relationships in various composite systems are explained with the help of theoretical models, while processing techniques for various macro- to nanocomposite systems and the influence of processing parameters on the properties of the composite are reviewed in detail. The characterization of microstructure, elastic, viscoelastic, static and dynamic mechanical, thermal, tribological, rheological, optical, electrical and barrier properties are highlighted, as well as their myriad applications. Divided into three volumes: Vol. 1. Macro- and Microcomposites; Vol. 2. Nanocomposites; and Vol. 3. Biocomposites.

Natural fibers and their composites have a long and important place in the history of human creativity and industry. Increasing consumer interest in "green" products made with sustainable materials, along with the rising cost of petroleum - the basic ingredient of synthetic fibers - have once again brought natural fibers and their composites to the fore. The renewed interest in natural fibers is only a few decades old. Thus, the pioneering work of current researchers in this new era of natural fiber composites will help to illuminate the path for future researchers as they explore new potentialities for natural fibers. Sabu Thomas and Laly Pothen, themselves leaders in the field, bring together cutting edge research by eminent scientists in Natural Fiber Reinforced Composites. Covering the latest research trends such as nano technology, the book will be a valuable resource for the natural fiber composite researcher.
