Linear low-density polyethylene (LLDPE) is widly used polymer in many fields. However, it has been not welcomed in food packaging application due to its poor oxygen barrier. Because of this, nanoclays have often been employed to improve gas barrier properties. In this study, maleic anhydride grafted linear low-density polyethylene LLDPE/organically modified montmorillonites (MMT) /Borosilicate glass hybrid nanocomposites with various contents and compatibilizers were prepared by melt mixing process with controlled residence time. The physical and mechanical properties of hybrid nanocomposites has been characterized, and the morphological observation was performed with the scanning electron microscopy (SEM). The reenforcing effect of both borosilicate glass and clay on the mechanical properties was found, and the barrier properties has been also improved due to increased tortuous path from hybrid filler effect as compared to that of neat LLDPE. |
