This book attempts to understand the multiple branches that fall under the discipline of nanocomposites and how such concepts have practical applications. Nanocomposites refers to the material with two to three dimensions of less than 100 nanometers. The different types of nanocomposites are metal-matrix nanocomposites, polymer-matrix nanocomposites and ceramic-matrix nanocomposites, etc. The various sub-fields of nanocomposites along with technological progress that have future implications are glanced at in this book. Most of the topics introduced in this book cover new techniques and the applications of nanocomposites. Different approaches, evaluations and methodologies and advanced studies have been included in it. This book is meant for students who are looking for an elaborate reference text on nanocomposites.
