摘要：

The intercalation process of hexadecylamine into bentonite and the fine structure of hexadecylamine in nanoscale confined space are studied by differential scanning calorimetry and X-ray diffraction. Intercalated amine exhibits multiple melting temperatures that are approximately 30 degreesC higher than the bulk amine, providing strong evidence that amine molecules assume ordered structures within silicate layers. Amine-packing density influences the interlayer fine structures of the amine as well as the stacking regularity of the silicate layers. With the further intercalation of polymer molecules, the ordered structure of amine is strongly influenced.
