In this study, A series of flame retardant epoxy/clay nanocomposites were prepared with a selected epoxy resin and a phosphorus-containing organoclay (PCg) pre-exfoliated by a mechanically grinding process. The results of X-ray diffraction (XRD), Fourier transform infrared (FTIR) and Field emission scanning electron microscopy (FE-SEM) showed that the ground organoclay was delaminated by the grinding process and well-dispersed with exfoliation structure in the epoxy matrix. The results of Limiting oxygen index (LOI) measurement indicated that an extraordinary enhancement on the flame retardancy was obtained for the nanocomposites prepared with the delaminated phosphorus-containing organoclay and ascribed to the synergy of the phosphorus fragment and clay revealed by the exfoliated PCg.
