The four methods by which nanomaterials are being produced in my laboratory will be described briefly. The methods are: sonochemistry, microwave dielectric heating, sonoelectrochemistry, and RAPET (Reaction under Autogenic Pressureat Elevated Temperatures). I will concentrate in my talk on the application of these nanomaterials for various applicative or industrial projects.

For example sonochemistry have been employed for coating nanosilver particles on Nylon 6, 6 chips. The nanocrystals of pure silver, 50-100 nm in size, are finely dispersed on the polymer surface without damaging the Nylon 6,6 structure. This Ag/nylon nanocomposite is stable to many washing cycles, and thus can be used as a master batch for the production of nylon yarn by melting and spinning processes.. The fabric knitted from this yarn has shown excellent antimicrobial properties. In Figure 1 we present three stages in the preparation of the final product.

Some other applicative examples of nanomaterials prepared by the microwave and RAPET techniques will be presented.
