In this work Poly (hexamethylene isophthalamide) (PA 6I) was synthesized via interface step polymerization at room temperature for the first time, here. Layered silicates were used in order to fabricate PA 6I nanocomposites by in-situ polymerization. Thermal, mechanical and morphological of obtained nanocomposites were examined. The dispersion effect of silicate layers in the matrix was studied by means of XRD and FE-SEM. The incorporation of layered silicates in PA 6I leads to a significant improvement in the mechanical properties of the resulting nanocomposites. The thermogravimetric analysis results showed that layered silicate incorporation enhances the thermal resistance of PA 6I nanocomposites. Improvements in thermal degradation properties, while Young’s moduli have also been modified.
