Outline of Final Research Achievements

Composite of a polymer film and metal nanoparticles, i.e., polymer-metal nanocomposites are already known to be useful for various purposes. However, the standard technique to synthesize nanocomposite films is to use the chemical reduction, which takes time for the synthesis. In this work we develop a new method to synthesis polymer-metal nanocomposite films using a CO2 laser, and demonstrate that the size and the number density of nanoparticles in the polymer matrix can be controlled by the choice of the density of the precursor of nanoparticles and the laser parameters.
