Characterizing Biaxially Stretched Polypropylene / Graphene Nanoplatelet Composites
In this work, polypropylene (PP) nanocomposites containing different boy romper weight concentration of graphene nanoplatelets (GNP) were prepared by melt-mixing using an industrial-scale, co-rotating, intermeshing, twin-screw extruder.The materials were then compression moulded into sheets, and biaxially stretched at different stretching ratios (S
