In-Situ Fabrication of Polymer/Metal Nanocomposite Films using a Mid-Infrared Laser

摘要

We demonstrate a very rapid in-situ fabrication of polymer/metal nanocomposite films. Using a CO_2 laser at 10.6 μm, Ag-PVA (polyvinyl alcohol) nanocomposite films are successfully fabricated on a glass substrate within 10 seconds, which is the most rapid method among any known fabrication methods. The fabricated films are characterized using the optical absorption, atomic force microscopy, and x-ray diffraction measurements.
