Thermal property, structure and morphology of the LDPE/ organo-clay nano-composites prepared melt blending were investigated by using thermogravimetric analyzer (TGA), X-ray diffractometer (XRD) and scanning electron microscope (SEM). When the composition ratios of the compounds of LDPE/PE-g-MA/organo-clay were 70-90/10~30/1~5 (w/w/w), thermogravimetric analyses (TGA) performed in air showed a great increase in thermal stability of the LDPE/organo-clay nanocomposties. The maximum decomposition temperature of LDPE/organo-clay nanocomposite was increased by about 80 ℃ compared with pure LDPE. X-ray diffractograms of LDPE/organo-clay nanocomposites showed that the intercalation of polymer chains lead to increase the spacing between clay layers.
