Polyamide-66(PA66)/CaCO3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. Nano-size of CaCO3 was synthesized by micro-emulsion technique. The material was characterized by XRD, SEM, FTIR and UV-VIS techniques. XRD results of composites suggested that CaCO3 particles are found in the amorphous phase of the semi-crystallin...

The properties of thin polymer films are known to be different than the properties of bulk polymers. Both dewetting studies1,2 and temperature-dependent thickness measurements3 showed that thin polystyrene films can exhibit polymer mobility even at temperatures well below that of the bulk-polymer glass transition (Tg). Subsequent work by a wide range of groups has shown that the thermal propert...
