Abstract
Palladium nanoparticles were incorporated into polyamide-clay nanocomposites using two step synthetic strategies. Primary step involved the formation of aromatic polyamide/DDA-MMT nanocomposites using solution interaction approach, followed by incorporation of palladium nanoparticles in the subsequent step using simple dry process. The resulting materials were characterized using X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). XRD and TEM results supported the formation of exfoliated nanocomposites displaying fine dispersion of clay as well as uniform distribution of Pd0 nanoparticles into the polyamide-clay nanocomposites. Morphological studies revealed that particle size of Pd0 nanoparticles were in the range 1–4 nm. Thermal stability significantly amplified upon the formation of polyamide/clay nanocomposite as compared to pure polymer. Furthermore, this thermal stability was augmented by the incorporation of Pd0 nanoparticles in the clay nanocomposites. Glass transition temperatures were also enhanced considerably upon the introduction of Pd0 nanoparticles in the clay nanocomposites.
