摘要：

Nanocomposites with highly dispersed mica layers in the polyamide 6 matrix were prepared by hydrolysis and polymerization of epsilon-caprolactam (epsilon-CL) under high pressure (19 kg/cm(2)) in the presence of expandable synthetic mica (NaMg2.5S4O10F2). Silicate layers of the starting mica were cleaved and highly dispersed into the polyamide 6 matrix, which was supposed to occur through the intercalation of epsilon-CL cations by exchanging with Na+ in the starting mica and then polymerization of epsilon-CL between the silicate layers. High bending strength and modulus of these nanocomposites were obtained as a result of cleaved thin layers with a high aspect ratio and the high dispersion.
