Abstract Combined effects of nanoclay and pro-oxidant on abiotic oxidation of polyethylene with different concentration of clay have been investigated in this study in order to prepare environmentally-friendly and economical polyethylene-nanoclay composites. Oxidation of polyethylene-nanocomposite film samples was carried out in an air-circulated oven. Morphology of nanocomposites was studied using wide angle x-ray diffraction (XRD) to investigate the degree of exfoliation/intercalation in nanocomposites. FTIR spectroscopy was used to evaluate the thermal oxidation rate of nanocomposites by measuring the intensity of carbonyl peaks in FTIR spectra and carbonyl index values. Experimental results showed that thermal degradation is improved noticeably due to the presence of pro-oxidant while the presence of clay act as a barrier for oxygen thereby slowing the thermal degradation rate.
