Preparation and Properties of Novel Polyamide/Sepiolite Nanocomposites

Polycondensation reaction of an aromatic sulfone ether diamine (containing four flexible ether and one sulfone groups) with terephthaloyl dichloride led to preparation of a flexible aromatic polyamide film. By introduction of different amounts of sepiolite nanoparticles into the backbone of polyamide matrix, related nanocomposites were prepared and their structures were characterized. Morphology of the polymer and nanocomposites were studied and compared via scanning electron microscopy, transmission electron microscopy. Improvement in the properties of the nanocomposite containing 3 wt.% sepiolite was observed in comparison to pristine polymer
