Abstract
We report the fabrication and characterization of stretchable nanocomposite films with mechanically tunable surface plasmon resonance. The films have been produced by implantation in a Polydimethylsiloxane substrate of neutral gold nanoparticles aerodynamically accelerated in a supersonic expansion. Optical absorption spectroscopy shows that uniaxial stretching of the nanocomposite induce a reversible redshift of the plasmon peak up to 180 nm from the peak wavelength of the non-stretched sample. The range of the plasmon peak shift depends upon the density of implanted nanoparticles. The optical behavior of the nanocomposite evolves upon cyclical stretching due to the rearrangement of the nanoparticles in the elastomeric matrix. We have identified the fabrication and post-deposition treatment conditions to stabilize the plasmonic shift upon cyclical stretching in order to obtain robust and large area nanocomposites with tunable and reproducible optical properties over a wide visible wavelength range.
