Morphological Caracterization of Polyethylene Terephthalate- TiO2 Nanocomposite

Morphological characterization of Nanocomposite of montmorillonite KSF (MMT)/Hexametylenediamine (HMDA) and synthesizind by using HMDA as an organic moiety and MMT in acidic medium at 80 0C is carried out. Preparation of nanocomposite with nanopartcles of TiO2 and polyethylene terephthalate (PET) were prepared in this work. The modified nanoclay/ nanocomposite were prepared in presence of ethylene glycol, terphthalic acid and modified nanoclay by polycondensation process. The Structure of the nanocomposites were evaluated by using X–Ray diffraction (XRD) and fourier transform infrared spectroscopy (FTIR). XRD spectrum showed that distance between layers of modified nanoclay were increased and these were suitable for preparation of nanocomposites by polymerization technique. Also FTIR and spectrums were confirmed existence of ammonium in the nanoclay. The morphology of this nanocomposite was also determined by scanning electron microscopy (SEM). These findings were showed that PET was polymerized into layers of modified nanoclay.
