Abstract

In this study high-density polyethylene (HDPE)/ maleic anhydride grafted polyethylene (PE-g-MA) nanocomposites, containing 1, 3, 5 wt.% of CaCO3 nanoparticles were provided by melt mixing process. Attendance of nanoparticles in PE matrix and addition of PE-g-MA led to enhancement of thermal stability of nanocomposites which proved by TGA analysis. In addition, kinetics of thermal decomposition of HDPE and its nanocomposites were examined. Addition of nano-particles led to enhancement of activation energy and degree of conversion.
