study of physical and thermal properties of polypropylene-tio2 nanotube nano composites

Abstract plastics occupy wide place in the applications of automotive, electronics and house goods# especially reinforced plastics become popular because of their high strength besides their advantages of low weight and easy manufacturability# in this study,thermal and morphological properties of polypropylene (pp) reinforced with titan oxide (tio2) nanotubes were investigated# the morphological characterization based on scanning electron microscopy has confirmed that nanotubes are distributed uniformly in the pp matrix that indicating a good dispersion of nanotubes# the thermal properties of the samples were examined using dsc and tga tests# the results show that the crystallization temperature of the nanocomposites significantly increases by adding tio2 while the melting point is not markedly affected# in addition, the thermal stability is improved#
