“…Similar effect was observed previously in talk functionalised with APTES, which showed an increase in the MFI compared to unfunctionalised one [56]. Also, in nanoclay/PA11 nanocomposites, at low loadings (2%), the APTES modified nanocomposite exhibited lower increase in viscosity compared to the unfunctionalised [57].…”

“…PA–montmorillonite (MMT) nanocomposites have been the subject of a considerable number of investigations because of their favorable mechanical, barrier, and flame‐retardant properties via the incorporation of very small amounts of MMT (<5 wt %) and has shown great potential for the packaging industry . However, the incorporation of MMT into the PA matrix often results in a deteriorated toughness, and this limits the application of the PA–MMT nanocomposites.…”

Polyamide 6-66 (PA6-66)-montmorillonite (MMT)-nanosilica (NS) nanocomposite films were fabricated through a cast film process and then biaxially stretched on a laboratory stretcher. Uniaxial or biaxial stretching induced the elongated conformation of MMT and NS. The b axis of the α crystals and the amorphous phase were revealed to align along the machine direction (MD) after stretching, with the uniaxial orientation playing a more significant role. Furthermore, the crystallinity of PA6-66 stretching increased with the stretching ratio. Uniaxial stretching gave rise to a significantly enhanced tensile strength along the MD, whereas it slightly decreased the mechanical properties along the transverse direction (TD). In contrast, the films subjected to biaxial stretching exhibited more balanced mechanical properties. Uniaxial and biaxial stretching led to decreased transmittance and increased haze in the PA6-66-MMT-NS films; this could have been due to the elongated nanostructure of the two nanofillers, which inhibited the transmission and facilitated the scattering of visible light. The thermal shrinkage of the films increased with increasing stretching ratio, and the biaxially oriented films presented nearly equal shrinkage in the MD and TD. The addition of nanofillers decreased the shrinkage attributed to the mobility inhibition of the polymer chains during heating.

In this study, PA6-66/γ-aminopropyltriethoxysilane-modified clay nanocomposites were prepared byin situpolymerization. It was found that the γ-aminopropyltriethoxysilane was chemically grafted onto clay successfully, and the covalent bond was formed between the clay and polymer chains. The transmission electron microscopy (TEM) and X-ray diffraction (XRD) results indicated that intercalated and exfoliated nanocomposites were obtained. The PA6-66 nanocomposites exhibited improved mechanical performance compared to that of neat PA6-66. Most importantly, the PA6-66 nanocomposites showed significantly improved toughness. In comparison with neat PA6-66, the rupture stress and elongation at the break of the nanocomposite with only 0.5 wt% clay increased 91.9% and 91.8%, respectively. The excellent toughness of PA6-66 nanocomposites should be mainly ascribed to the combined effects of strong polymer-clay interaction, the intercalated-exfoliated structures of clay, refined crystalline, formation of γ-form crystals, and decreased crystallinity of PA6-66.
