Mechanical, rheological and thermal properties of extruded graphene filled PP composites produced in a twin-screw extruder
In this study, graphene reinforced Polypropylene nanocomposites were produced by using a twin-screw extruder in industrial scale, which achieves a lower energy input compared to laboratory scale experiments. The degree of dispersion and the resulting material properties are the focus of this study. Different graphene and graphene oxide types with different specific surfaces and filler contents are used for this purpose. The analysis of the dispersion of the nanofillers shows agglomerates in the matrix. Both the crystallinity and crystallization temperature of the PP is influenced significantly through the adding of graphene, while melting temperature is not being affected strongly. Young´s modulus increases with increasing filler content, whereas tensile strength is not improved by the adding of the used graphene types.
