Polymer-clay nanocomposites have flame-retardant, antimicrobial, anticorrosion and self-healing properties, they are biocompatible and environmentally benign. Multiple types of clay minerals may be exfoliated or individually dispersed and then used as natural nanoparticle additives of different size and shape for composite formation. Loading polymers with clays increases their strength, however, it is only recently that such composites were prepared with controlled nanoscale organization allowing for the enhancement of their mechanical properties and functionality. Edited by pioneers in the field, this book will explain the great potential of these materials and will bring together the combined physico-chemical, materials science and biological expertise to introduce the reader to the vibrant field of nanoclay materials. This book will provide an essential text for materials and polymers scientists in industry and academia.
