| Abstract | Low-density polyethylene (LDPE)/organoclay (cloisite 20A, abbreviation: C20A) nanocomposites were melted in this exploration by intercalation technique with low molecular weight oxidized polyethylene (OxPE) as a coupling agent. The effects of OxPE on morphology, mechanical, thermal, flame retardant properties were identified by transmission electron microscopy (TEM), X-ray diffraction (XRD), tensile test, differential scanning calorimetry (DSC), and flammable tests, respectively. XRD and TEM results exhibited that the interlayer distance of the nanoparticle layers were increased and a partial intercalated structure was prepared with an intercalated technique. Mechanical experiments exhibited that the inclusion of 5 wt% C20A in LDPE was significantly improved the tensile strength and tensile modulus with reduced elongation at break compared to base polymer LDPE. The inclusion of OxPE in LDPE/C20A further enhances the tensile properties of nanocomposites. In the case of virgin LDPE, there was an increase of 53% for tensile strength and 66% for tensile modulus. Nevertheless, the crystallization temperature of the specimens increased significantly and the degree of crystallization in the nanocomposite increased with increasing coupling concentration. Substantial enrichment of flame retardant properties has been observed for ternary nanocomposites. |
