Learn How to Design Environmentally Friendly Polymer Blends and Composites

Highlighting important new developments and findings, this book explores biodegradable polymer blends and composites from renewable resources and points to their potential markets. Readers will discover how to work with blending and composition formulations to create new, environmentally friendly products with valuable properties.

Following a general introduction, the book is divided into six parts:

• Part I focuses on natural polymer blends developed with melting, aqueous, or reactive blending.

• Part II demonstrates how to improve the thermal properties of aliphatic polymer blends.

• Part III discusses hydrophobic and hydrophilic blends, in particular polyesters and natural polymers.

• Part IV examines composites reinforced with natural fibers.

• Part V introduces the development of nanoclay-reinforced composites, including novel techniques to delaminate clay for use in natural polymers.

• Part VI investigates multilayered systems from renewable resources.

By exploring the relationship between microstructure and properties for each category of blends and composites, the book helps readers design their own materials. In addition to standard techniques, readers learn several innovative, advanced techniques for improving the interfaces between hydrophilic natural polymers and hydrophobic biodegradable polyesters. Readers also learn the latest techniques for analyzing and working with biodegradable nanocomposites.

Combining fundamental science with applications that have either been commercialized or show great promise for commercialization, this book is ideal for material and polymer scientists as well as students who are interested in bringing new environmentally friendly products to market.

Yu (Commonwealth Scientific and Industrial Research Organization) and 34 co-contributors provide an instructional reference for blending and composition formulations to use in creating new environmentally-friendly compounds. In addition to standard techniques, the book describes innovative, advanced techniques intended to improve the interfaces between hydrophilic natural polymers and hydrophobic biodegradable polyesters. It also offers the most current techniques for analyzing and working with biodegradable nanocomposites. Generally, this reference combines fundamental science with applications that are being used commercially or show substantial promise for commercial use. Clearly written and with extensive references. Of interest to polymer and materials scientists and students. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)

Biodegradable Polymer Blends and Composites from Renewable Resourcesprovides a comprehensive, current overview of biopolymeric blends and composites and their applications in various industries. The book is organized according to the type of blend or composite. For each topic, the relationship between the structure of the blends/composites and their respective properties is explored, with particular focus on interface, compatibility, mechanical, and thermal properties. Real-life applications and potential markets are discussed. This is a premier reference for graduate students and researchers in polymer science, chemical and bio engineering, and materials science.

Long Yu, PhD, is highly regarded in the field of polymer science, with more than twenty-five years of experience in developing and finding new applications for polymeric materials. He is currently working as a research scientist in Commonwealth Scientific and Industrial Research Organization (CSIRO), Materials Science and Engineering Division, Australia. He is also a visiting professor at South China University of Technology. Dr. Yu is a Fellow of the Royal Australian Chemical Institute.
