چکیده:

In this work the nonlinear viscoelastic properties of polyamide 6/ Acrylonitrile–Butadiene–Styrene (PA6/ABS) nanocomposite blends have been investigated. Overshoots were observed for the start-up experiments. The height of these overshoots increased with the applied shear rate. The overshoots are highly related to the network structure of the nanocomposite blends and the magnitude of the overshoots increases with increasing nanoclay content. Characterization of nanocomposite samples morphology by scanning electron microscopy (SEM) indicated that with increasing nanoclay loading, size of dispersing phase droplets decreases and their uniformity improve significantly
