Abstract

Polypropylene nanocomposites were prepared using zinc oxide as the filler by melt mixing process. Nanocomposites were also prepared using maleic anhydride grafted polypropylene and methylated-zinc oxide using the same method. The samples were analyzed for observing changes in morphology and thermal stability using various characterizing instruments. The results showed that zinc oxide induced changes in the morphology and thermal stability of polypropylene, though by varying amounts depending on the type of nanocomposite prepared. The nanocomposites prepared from g-PP and methylated zinc oxide showed significant changes in crystallization temperature, decomposition temperature and residue formed upon decomposition, as compared to the rest of the composites or control samples. This was attributed to higher degree of interaction existing at the interphase between the organic and inorganic phases for these nanocomposites.
