Viscoelastic properties of exfoliated polyamide-6/layered silicate nanocomposite

The effect of interfacial interaction on the characteristic structures formed and on the viscoelastic properties of exfoliated polyamide-6/layered silicate nanocomposite, was analyzed. X-ray diffraction (XRD) measurements were performed using a Philips PW-1847 diffractometer with CuKα characteristic radiation to confirm exfoliation and structure of the prepared nanocomposites. The rheological properties measured at 240°C for PA6 and its nanocomposite containing Nanofil 784 are plotted as a function of angular frequency. The results show that XRD diffractograms indicate a large extent of exfoliation of the silicate caused by strong interfacial interaction between PA6 and Nanofil 784.
