Abstract

AbstractA novel nylon 6/11/montmorillonite nanocomposite was prepared by in situ copolymerization of prepolymer of caprolactam with aminoundecanoic acid in the presence of organoclay, and characterized in terms of Fourier transform infrared (FTIR) spectroscopy, wide-angle X-ray diffraction (WAXD), transmission electron micrograph (TEM), intrinsic viscosity as well as differential scanning calorimetry (DSC). It was found that the addition of organoclay had great influence on the intrinsic viscosity and melting behavior but not on the crystal transition of nylon 6/11 matrix. Intercalated/exfoliated and stacked silicates layers were observed for various nanocomposites.
