Nanocomposite Films

Abstract

Nanocomposites have become an important class of materials as they allow to combine somehow contradictory materials properties in a complementary way in one material. The use of inorganic-type nanoparticles in sol-gel-derived or polymer-type matrix by wet chemical synthesis approach allows to incorporate solid-state physical properties of ceramics even into transparent polymers without decreasing transparency in the visible range. The chapter presents key results and structure–property relationships of nanocomposite films usable to produce functional coatings or paints. Concepts such as control of interfacial adhesion , particle surface modification for compatibilization and synthesis parameters that determine specific morphologies are presented. Mechanical properties in dependence on the morphology as well as dynamic mechanical behaviour in dependence on nanoparticle/matrix interaction and particle size of the nanoparticulate inclusions are covered.
