| The development of nanocomposite coatings has followed the development of modified nanoparticles themselves. The understanding of nanoparticle surface modification has enabled the development of nanocomposite coatings. In the last decade, surface engineering of inorganic nanoparticles has advanced to the point that it has become possible to fabricate and tune the functional properties of nanoparticles. When the surfaces of inorganic nanoparticles are correctly designed, they can be fully dispersed into polymers resulting in the formation of polymer nanocomposites having exceptional thermal, mechanical and barrier properties. The final properties of a nanocomposite are related to the nanoparticle itself (aspect ratio), the degree of dispersion, and the identity of the surface groups (surface density, oligomer length, etc.) Additionally, surface engineering can produce functional nanoparticles and by extension functional nanocomposites. At the most basic level, functional nanoparticles are surface engineered to both disperse into a host phase (e.g. a coating) and to carry the functional agent. We will discuss the relationships between nanoparticle surface modification and nanoparticle dispersion, nanocomposite properties, and the development of “Smart” coatings. |
