Morphology and melt rheology of nylon 11/clay nanocomposites [PDF]

, 2006
Nylon 11 (PA11)/clay nanocomposites have been prepared by melt-blending, followed by melt-extrusion through a capillary. Transmission electron microscopy shows that the exfoliated clay morphology is dominant for low nanofiller content, while the ...
