ABSTRACTFundamental principles of nanocomposites are discussed. The basic features of nanocomposites are low dimensionality of their composition components, widespreadness of the electronic interactions between the components and the great variety of microstructure of nanocomposites ranging from high level ordered 3-dimensional periodic structure to stochastically dispersed medium of superfine particle. All these offer much more potential for tailoring the property of materials than by formation of chemical compound or mixture including microcomposites. Vapour deposition enhanced by ion beam and electrical discharge plasma provides a class of versatile processes both for preparing low dimensional components of nanocomposites and for synthesizing nanocomposite film itself. Elements of designing nanocomposite thin films and their preparing by ion beam and plasma enhanced vapour deposition are also discussed. Examples of nanocomposite films are given.

Metal Volume

The development of new fabrication techniques of plasmonic nanocomposites with specific properties is an ongoing issue in the plasmonic and nanophotonics community. In this paper we report detailed investigations on the modifications of the microstructural and plasmonic properties of metal–titania nanocomposite films induced by swift heavy ions. Au–TiO2 and Ag–TiO2 nanocomposite thin films with varying metal volume fractions were deposited by co-sputtering and were subsequently irradiated by 100 MeV Ag8+ ions at various ion fluences. The morphology of these nanocomposite thin films before and after ion beam irradiation has been investigated in detail by transmission electron microscopy studies, which showed interesting changes in the titania matrix. Additionally, interesting modifications in the plasmonic absorption behavior for both Au–TiO2 and Ag–TiO2 nanocomposites were observed, which have been discussed in terms of ion beam induced growth of nanoparticles and structural modifications in the titania matrix.

Improving the physical and mechanical properties such as hardness and strength of metal thin films can be achieved by incorporating nanoparticles into the pure metals, for example via electrocodeposition. However, the agglomeration of nanoparticles during electrocodeposition of nanocomposite thin films is an unresolved issue. This paper presents the preliminary results of electrocodeposition thin nanocomposite films under different processing conditions. The microstructure and distribution of Al2O3 nanoparticles in electrocodeposited Cu matrix nanocomposite thin films on a pure Al plate were examined. In addition, the effect of electrolyte concentration on the agglomeration of nanoparticles was studied. Different stirring times were used for electrodepositing the alumina/Cu nanocomposite and the pure Cu control film. Under the constant stirring condition, different deposition times including 1, 4, 8, 12, and 24 hours were taken to study the differences between the agglomeration states of the alumina nanoparticles with the time change. We also examined the effect of turning the electromagnetic stirrer ON and OFF at different time intervals from as short as every 20 minutes to as long as ON and OFF every 2 hours on the nanoparticle agglomeration in the film. Optical and electron microscopic studies were made to reveal the microstructure of the nanocomposite. It is found that there is no significant difference in microstructures for the specimens that made under either intermittent stirring or constant stirring for the same length of time.
