The development of nanostructured coatings with improved abrasion resistance, electromangetic shielding, thermal conductivity, refractive index, and transparency reuqires careful manipulation of material composition, nanostructure size, and composite structure. The selected materials must be processable and yield the desired physical properties. THe correct nanostructure size is importnat because often multiple physical properties are desired, i.e., conductivity o abrasion resistance with transparency. The corret composite structure must be selected for hte desired physical property form uniform surface distribution for abrasion resistance to connected structures for elctrical conductivity. Nanostructured coatings formed by the additio of dense, crystalline nanoparticles to a contionuous second phase will be discuesed. The particles are manufactured by gas phase condensation and the continuous phase vareies from epoxy polymers to silica. Particle size, material composition and surface treatments ar manipulated to control composite properties and structure. Transparent/conductive and transparent/arasio rsistnt coatings will be discussed with respect to a broad range of market applciations including electronic materials, opticla nad mangetic devices, catalysts and structural materials.
