During the last decades, dealing with the increasing amounts of industrial non-biodegradable disposals polluting the environment has emerged as one the major concerns of researchers, as well as ordinary public associations. Since, biodegradable polymers produced from nontoxic materials, become increasingly noticed as replacements of conventional non biodegradable petroleum-based plastics. This book, therefore, provides a new class of environmentally friendly biodegrabale nanocomposites of polycaprolactone-chitosan-layered silicate with enhancement in mechanical and thermal properties.
