The Characteristics of PA-6/Clay and PA-66/Clay Nanocomposites

摘要

Nanocomposites based on polyamide 66 (PA-66)/clay and polyamide 6 (PA-6)/clay were prepared using a twin-screw extruder. The nanocomposites were characterized with transmission electron microscopy (TEM), X-ray diffraction (XRD), differential scanning calorimetric (DSC), optical microscopy and tensile testing. Effects of processing condition and clay modifier were also studied. The results show that mixing, shearing elements and higher residence time in the twin-screw extruder are effective factors in enhancing exfoliation. The characteristics of the two types of nanocomposites will be compared.
