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.
