Some 3500 visitors attended the NanoEurope event in St.Gallen in mid-September to familiarize themselves with promising future applications of nanotechnology. One of the focal subjects discussed was plastics and polymers, to which nanoadditives impart entirely novel functionalities.
Nanoadditives offer the potential for developing novel products and processes, since the characteristics of engineering materials may change fundamentally at the nanometer scale.
Optical effects of polymer nanocompounds
Certain optical and electronic characteristics cannot be achieved at the micrometer scale, confirms Dr. Walter Caseri from the Swiss Federal Institute of Technology (ETH) in Zurich.
