Polyamide 11 (PA 11) is a widely used polyamide resin

but its application is limited since the impact properties

tensile strength

and thermal properties are not very satisfactory for industrial application. In order to improve the mechanical properties of PA 11

in this paper

the preparation of polyamide 11/clay nanocomposites (PACN) via in-situ intercalated polymerization was reported. SEM

TEM and XRD were employed to investigate the dispersion of clay sheet in the matrix. The results indicate that clay layers were homogeneously dispersed in PA11 matrix on a nano-scale

and an exfoliated and intercalated structure co-existed in the composites. The mechanical and thermal properties of the obtained nanocomposites were improved to certain extent by the addition of clay.
