Effect of Few-Layer Graphene on the Properties of Mixed Polyolefin Waste Stream

This work demonstrates how the addition of few-layer graphene (FLG) influences processability and mechanical properties mixed polyolefin waste stream (R-(PE/PP)). Three different types compounds were investigated: (1) R-(PE/PP) with FLG; (2) blends prime polyethylene (PE) or polypropylene (PP) PP copolymer; (3) both polymer FLG. The was assessed by measuring torque during melt extrusion, flow index (MFI), viscosity compounds. Investigations composites indicate that presence FLG can reinforce without hindering processability, an unusual but desired feature rigid fillers. A maximum increase in tensile strength 9%, flexural 23%, a reduction impact observed for containing R-(PE/PP), 4 wt.% FLG, 9 PP. concentrations higher than however, resulted while preserving strength. Remarkably, 10 increased composite 9%. is attributed to dominant resistance particles crack propagation.
