This work explores the use of composite nanotechnology for thin coatings on various substrates. It compiles recent advances in nanocomposite coatings for experienced researchers and provides background information for those new to the field. The book not only explains the synthesis of bulk nanocomposite materials, it describes their application in areas such as the automotive and packaging industries. It explains how nanocomposite coatings provide a gas barrier to the substrate foil or laminate and how the coatings are used to provide properties such as anti-scratch and anti-corrosion. "The book describes the polymer nanocomposite coatings methodology, which is used in many commercially important fields like biomedical, automotive, packaging etc. Moreover, efforts have been made to provide a broader reachwith discussions devoted to the controversial issue of the regulation of harmful effects (toxicity) of some coating substances especially in the biomedical and food industry. The book has balanced content, gathering together the most relevant information regarding numerous industrial coatings systems including silver-polysaccharide, carbon nanotubes-polytetrafluoroethylene, chitosan-magnesium aluminum silicate nanocomposites etc., provided by the various academic experts. The text also includes comprehensive overview of the various processing/polymerization methods and characterization possibilities in the field of polymer nanocomposite coatings, and thus acts as a valuable reference text providing up-to-date learning and research advances for beginners as well as experts in the area."-Nadejda Matsko, Graz Centre for Electron Microscopy
