摘要：

Nanocomposites based on Polyamide 6 (PA6) blends were developed using organically modified clay (organoclay) and a compatibilizer. The nanocomposites were prepared in two steps. First, PA6 was pre-mixed with the organoclay in an internal mixer forming a concentrate. In the second step, this concentrate was diluted in either PA6, PA6/EG, PA6/HDPE or PA6/EG/HDPE blends in a twin screw extruder. The degree of dispersion of the clay in the polymer was evaluated through X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). XRD results indicated that for PA6/EG/CL20A and PA6/EG/HDPE/CL20A systems, a partially exfoliated structure was obtained. SEM analysis results showed that the organoclay is well dispersed in the polymers. The presence of the compatibilizer improved the impact strength of the PA6/CL20A and PA6/HDPE/CL20A systems.
