Corrosion causes permanent damage to metal surfaces and is a major global challenge, spanning numerous fields including industrial sectors, construction materials, and surface treatments for metallic cultural heritage preservation. Nanomaterials and nanocomposites can be used as effective alternative corrosion inhibitors in the place of traditional environmentally toxic substances. This book provides readers with an overview of the properties and applications of nanomaterials and nanocomposites as corrosion inhibitors. Chapters first cover the basics of nanomaterials and the features that make them useful candidates, before highlighting recent advances from across the field for industry-oriented challenges. With a focus on cutting-edge research, this book is a valuable resource for chemists, chemical engineers, material scientists and environmental chemists in both academia and industry who want to learn more about corrosion inhibitors and mechanisms.
