Nanomaterials produced using gas aggregation source of nanoparticles

The gas aggregation source of nanoparticles (GAS) is nowadays a well-established tool for synthesizing different nanomaterials on a lab-scale for more than two decades. The main research interest moved in the time from a synthesis of single metal, size-selected nanoparticles towards development of complex nanostructures like nanocomposite films or composite multi-component nanoparticles (NPs).

In the presented study, possibilities of fabrication of nanocomposite films with NPs inclusions made by means of GAS will be discussed. Special attention will be devoted to the limitation of different deposition techniques for hard polymer/metal nanocomposite coatings.[1,2]

The use of the GAS is also extensively studied for the production of heterogeneous nanoparticles with different structures. The most common approach is a synthesis of such NPs in one aggregation chamber either by sputtering from a composite target or in a so-called multi-magnetron arrangement. Another option, an in-flight coating of the nanoparticles will be discussed in this work. Different experimental arrangements and their effect on the final structure of the nanocomposite NPs will be reviewed. [3,4]
