Free-Standing Thin Films Containing Hexagonally Organized Silver Nanocrystals in a Polymer Matrix

摘要

In this communication, we report the successful preparation of novel thin nanocomposite films containing continuous periodic arrays of self-assembled silver nanocrystals in a polystyrene matrix. In the monolayer areas of the film, the silver nanoparticles are hexagonally arranged. Two different geometrical packings are observed in the bilayer sections. We suggest two schematic models for the interpretations of these interesting patterns.
