摘要：

The ultra high molecular weight polyethylene (UHMWPE)/organoclay nanocomposites were prepared in decalin with various organoclay contents (0, 1, 2, 3, and 5 pphr). Transmission electron micrographic images and X-ray diffraction results showed that the organoclay was exfoliated and well dispersed in UHMWPE matrix. The rheological properties were measured at various temperatures (110, 130, and 150 degrees C) in a broad range of shear rate (10(-1)-10(2)) at a gel concentration of 6 wt %. The result showed that the viscosity increased with the addition and increasing organoclay content. Thermal stability (thermogravimetric analysis) and crystallinity (differential scanning calorimeter) of UHMWPE increased with increasing organoclay content implying that the organoclay functioned as barrier and nucleating agent.
