AbstractIn this paper, effect of clay modification and the resultant clay dispersion and orientation structure on the photo-oxidation of polyethylene has been investigated upon ultraviolet exposure using the technique of infrared spectroscopy. Polyethylene/clay nanocomposites have been prepared using different clay modification. Both the pristine MMT clay and CTAB ammonium intercalated clay were modified via grafting reaction of silane with hydroxyl groups on the clay edge. The grafting modification leads to decreased photo-oxidation rate compared with that of neat PE, while the pristine MMT and ammoniums accelerate the photo-oxidation rate of the corresponding composites. Effect of the dispersion and orientation structure of clay in polymer matrix has also been discussed. In addition, the influence of photo-oxidation behavior on crystallization and morphology of the composites was studied by means of DSC and SEM.
