摘要：

The non-isothermal crystallization behaviors of polyamide 6/clay nanocomposite (PA6CN) were investigated by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). DSC results showed that the nanometric silicate layers in PA6CN acted as effective nucleation agents. The addition of silicate layers influenced the mechanism of nucleation and the growth of PA6 crystallites. The DSC results also implied an unusual phenomenon, in contrast to PA6, the crystallinity degree of PA6CN increased with increasing cooling rate. XRD results verified this phenomenon and indicated that the addition of silicate layers favored the formation of the gamma crystalline form. (C) 2002 Elsevier Science Ltd. All rights reserved.
