Crystalline phase transition in nylon-6 / singlewalled carbon nanotube nanocomposites

Resumen del póster presentado al Internantional Meeting on the Chemistry of Nanotubes: Science and Applications (ChemonTubes), celebrado en Zaragoza del 6 al 9 de abril de 2008.Polyamide-6 (nylon-6) is an important semicrystalline polymer which is used in many engineering products, such as fibres, films and various molding articles. Reinforcement of nylon with nanoparticles is one of the pioneering areas in the field of nanocomposites. Current investigations are mainly focused on the mechanical properties of nylon / carbon nanotubes, which are affected by the dispersion of the nantubes in the polymer matrix and the interfacial adhesion between reinforcement and matrix. However, knowledge of the influence of carbon nanotubes on the thermal behaviour of nylon nanocomposites is still scarce. The purpose of this work is to investigate the effect of the concentration single-walled carbon nanotube (SWNT) on nylon-6 crystalline phase transition processed by melt-mixing using micro-extruder (Thermo-Haake Minilab system, wt.%=0.1-1, 240ºC/10min/150rpm).The CSIC for a postdoctoral contract (I3PDR-6-02), financed by the European Social Fund.
