Description
Summary:The effect of the functionalization of polypropylene by different chemicals on the fabrication and properties of the resulting nanocomposites was studied. Different nanocomposites were prepared using different functionalized polypropylenes (PP) as coupling agents. In order to have better control of the interaction between the functional groups and the clay, samples were mixed in a Brabender plasticorder. The nanocomposite properties were then investigated. Different analysis techniques were used to characterize the dispersion and the properties of the nanocomposites including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction analysis, dynamic mechanical analysis (DMA) and a conventional flexural test. On a étudié l'effet de la fonctionnalisation du propylène par différents produits chimiques sur la fabrication et les propriétés des nanocomposites qui en résultent. On a préparé divers nanocomposites en utilisant différents polypropylènes (PP) fonctionnalisés comme agents d'accrochage. Afin d'avoir un meilleur contrôle de l'interaction entre les groupes fonctionnels et l'argile, on a mélangé les échantillons dans un "plasticorder" Brabender. On a ensuite évalué les propriétés des nanocomposites. On a utilisé diverses techniques d'analyse pour caractériser la dispersion et les propriétés des nanocomposites, incluant la microscopie électronique à balayage (SEM), la microscopie électronique à transmission (TEM), l'analyse de la diffraction des rayons x, l'analyse mécanique dynamique (DMA) et un essai conventionnel de pliage.
