Abstract
In the present study, the nanoSiO 2 and nanoZrO 2 were used as the fillers for linear low-density polyethylene (LLDPE) nanocomposites. In fact, the LLDPE nanocomposites were synthesized via the in situ polymerization of ethylene/1-octene with a zirconocene/MAO catalyst in the presence of the fillers. The LLDPE–nanocomposites were further characterized by means of TEM, DSC, 13C NMR and XPS. It was found that productivity increased more when the nanoZrO 2 filler was applied. The similar distribution for both fillers was observed by TEM. Based on the 13C NMR results, it appeared that the LLDPE nanocomposites obtained from both fillers were random copolymer. In particular, the resulted binding energy and elemental concentration at surface obtained from XPS measurement were further discussed in more details.
