Structures and Mechanical Properties of PVC/Na⁺-Montmorillonite Nanocomposites

Research Institute of Polymer Materials, Shanghai Jiao Tong University, Shanghai 200240

Received Date: 24 May 2002

Poly (vinyl chloride)/Na⁺-montmorillonite (PVC/MMT) nanocomposites with different MMT contents were prepared via melt blending. Wide-angle X-ray diffraction (WAXD) and transmission electron microscopy (TEM) were used to characterize the structures. Effects of MMT content on the mechanical properties were also studied. It is found that PVC molecular chains can intercalate into the gallery of MMT layers during melt blending process, the stiffness and toughness of the composites are improved simultaneously within 0.5~7wt% MMT content, and the transparency and mechanical properties decrease as MMT content further increases.
