Preparation of silver-polystyrene heterogeneous nanocomposite particles by alcohol reduction method

Abstract

Silver nanoparticles were successfully deposited on the polystyrene surface using alc. redn. method. In this process, sulfonate groups were employed as a chem. protocol to make a binding between silver nanoparticles and polystyrene surface. A large no. of quasi-spherical silver nanoparticles were formed and strongly attached to the polystyrene surface modified with sulfonate groups. The resulting composite particles were analyzed by transmission electron microscopy (TEM) and UV-vis spectrophotometer. The most distinguished features of this novel prepn. route include simple operation and absence of the toxic reducing agent. In addn., this novel prepn. route can be extended to the prepn. of other noble metal-polymer heterogeneous nanocomposites.
