Abstract

In this study, structure and properties of various hybrid composites of high-density polyethylene (HDPE) containing thermally reduced graphene (TRG) and elemental sulphur were investigated. Samples of HDPE-TRGS hybrid composites were fabricated by twin-screw extruder and injection molding machine in accordance with the standard test specimens. Mechanical properties and morphology of HDPE and HDPE-TRGS hybrid composites were examined by universal testing machine (UTM), TEM and SEM. Furthermore, AT- FTIR, XRD and Raman spectroscopy, examinations were performed to establish the structure-properties relationships. The mechanical properties significantly improved, when the proper amounts of TRGS materials were added to HDPE. The tensile strength of the hybrid composites was increased with insignificant loss of elongation. These improvements in properties are mainly due to the compatibilizing effect of TRGS and polymerization of octasulfur rings. TEM and SEM studies show that the graphene and sulfur were dispersed in HDPE matrix uniformly and make the composite more compactable. Elemental mapping and EDAX spectra showed that sulfur is present in the composite and distributed uniformly.
