Shape and size of filler vs. mechanical properties and flammability of polystyrene nanocomposites

Abstract

Presented work deals with the evaluation of the connection between the shape of (nano)filler and the polystyrene (nano)composites. Fillers and nanofillers with various type of particles (spherical, tubes, layered...)were chosen for the preparation of PS composites and nanocomposites. All samples were prepared by the compounding i.e. by the mixing in the melt of PS. Morphology and the level of distribution was evaluated by XRD and TEM. Next flammability and mechanical properties were observed. The best result was achieved with the layered mineral nanofiller Cloisite Na+.
