Investigation of The Mechanical and Thermal Properties of Graphene Oxide Filled Polypropylene Composites
In this study, the effect of graphene oxide (GO) on the mechanical and thermal properties of polypropylene (PP) composites were examined. Twin screw extruder was used for preparing the GO filled PP polymer granules. Injection molding method was utilized to produce graphene oxide/PP nanocomposites. According to tensile tests, the tensile strength and modulus of elasticity of PP matrix were increased by 42% and 71% with GO reinforcement, respectively. Conversely, the elongation at break and impact strength were decreased by 341% and 56% respectively. Also, the prepared GO/PP nanocomposite represented higher thermal stability as heat deformation temperature (HDT) and the vicat softening temperature (VSP) were simultaneously increased. The fracture surfaces obtained after tensile test were analyzed by scanning electron microscopy. KeywordsGraphene oxide, Mechanical properties, Thermal Properties
