Abstract

Silver nanoparticles/polystyrene nanocomposites were prepared via casting the solution of polystyrene in a mixture of carbon tetrachloride and acetone containing silver nanoparticles. Colloidal silver nanoparticles in acetone were synthesized by pulsed laser ablation of pure bulk silver. Nd:YAG laser at wavelength of 1064 nm, 130 mJ/pulse energy, 10 ns duration and reparation rate of 10 Hz has been employed to synthesis of nano silvers. TEM images show rather spherical nanoparticles with mean diameter of 3 nm. Silver nanoparticles in acetone are stable even after 8 months. Optical measurements of nano silver in acetone exhibit single maximum of optical extinction at 399 nm which is related to surface plasmon resonance. Casting the solution of nano silver in a mixture of carbon tetrachloride, acetone and polystyrene results a transparent polymeric sheet in light yellow color. Maximum of optical extinction of the sheet appeared at 428 nm and exhibited a red shift due to change of refractive index of the medium. The peak optical extinction spectra are in agreement with that calculated from the Mie theory for 5 nm spherical silver particles in polystyrene. This study demonstrates that hybridizing of pulsed laser ablation in liquids with casting method provides a simple, applicable and flexible technique in order to fabricate nanocomposite from different metals and polymers.
