The effect of PP/PA6 blend compositions on morphology and mechanical properties of PP/PA6/Organoclay nanocomposites

Different compositions of PP/PA6 blends and their nanocomposites containing 4 phr organoclay (Closite 15 A) and 5 phr PP-g-MAH as a compatibilizer were prepared using a twin screw extruder. Mechanical properties of samples were studied by tensile and Izod Impact tests. Morphology of nanocomposites was studied by SEM and TEM microscopies. It was found that nanoclay particles are located in PA6 phase and at the interface of two polymers. The best mechanical properties belonged to nanocomposites containing the major phase of PA6, which was due to the higher affinity of nanoclay to polar PA6. The intercalation of nanoclay particles was confirmed by X-ray diffraction (XRD) and TEM microscopy
