A Wafer of Polyethylene: Ultrathin polyethylene films made of nanocrystals

Layers of plastic, much thinner than a strand of hair—this type of ultrathin polymer film is of great interest to scientists and engineers. Applications include protective coatings, for example. A research team led by Stefan Mecking at the University of Konstanz has now developed a new method to produce wafer-thin layers. As reported in the journal Angewandte Chemie, the scientists made their films from individual prefabricated nanocrystal building blocks.
