Abstract
The influence of the silicon nanoparticles on the structure and optic properties of the polystyrene-based nanocomposites was investigated. PS+Si nanocomposites were prepared by combinations of the solution blending and hot pressing methods. The EDS spectrum of Silicon characterizes the high purity of nanoparticles. The XRD study of the nanocomposite samples shows that silicon nanoparticles play not only the role of filler but also have a structure-formatted function in the nanocomposite. PL properties of the polymer nanocomposite also prove that silicon nanoparticles, play the role of the center of the structure to format a more ordered arrangement in the polymer matrix. It was clear that the PL emission of the nanocomposite enhanced with the introduction of the silicon nanoparticles at the 450-550 nm region. This increase results in the expansion of the emission region of the pure polystyrene by the addition of a few amounts of silicon nanoparticles. This PS+Si nanocomposite could be an effective material for biomedical applications as a fluorescent marker for drug delivery systems.
