Polyamide-6 nanocomposites were prepared from a new phosphonium organoclay obtained at pilot scale in supercritical carbon dioxide (scCO 2 ) and a commercially available ammonium modified-silicate. The composites were homogenised by twin-screw extrusion, then specimens for testing were prepared by injection moulding. The clay content of the composites was varied from 0 to 7 vol.% in 7 steps...
Polymer nanocomposites containing layered silicates have been considered as a new generation of composite materials due to their expected unique properties attributed to the high aspect ratio of the inorganic platelets. Nevertheless, addition of layered silicates to polyolefins mostly results in phase separated systems because of the incompatibility of the silicates with the non-polar polyolefins...
