The microstructure and mechanical properties of fibrillar attapulgite reinforced nylon 6 nanocomposites

The nylon 6/attapulgite nanocomposites were prepared by melt compounding in a twin-screw extruder. The crystallization structure and fractured surface of the composites were analyzed by X-ray diffraction patterning (XRD) and scanning electron microscopy (SEM). The mechanism of attapulgite reinforced nylon 6 was explored. The results showed that the tensile strength of the composite increased with the increase of the content of the attapulgite,and was 32.6% higher than that of PA6 matrix when the content of AT gets to 10%,and the impact strength of the composite enhanced 31% compared with PA6 matrix,when the content of the attapulgite was 5%.The thermal properties improved with the attapulgite content increasing.
