Deformation mechanism of polystyrene-clay-SEBS nanocomposite

Nanocomposites based polystyrene (GPPS Tabriz Petrochemical) containing montmorillonite and SEBS by melt intercalation technique using a twin, co-rotating extruder with a starve feeding system prepared in this research. Structure and deformation mechanism of nanocomposites investigated. In order to investigate the structure of systems XRD and TEM and in order to study the deformation mechanism of samples optical microscope were used. The results of experiments show that organoclays act as initiation sites for crazing in polystyrene system and they can alter the mechanism from local to massive
