Abstract:Organic rectorite clay (OREC)/polypropylene(PP) nanocomposites were prepared by melt processing. OREC was obtained from natural rectorite through ion exchange w i th a quaternary ammonium salt. The morphological features of the composites were investigated by using the X\|ray diffraction and TEM techniques. It was found t hat the spacing of 001 crystalline planes for OREC slightly increased, when it w as blended with PP. The introduction of OREC showed evident positive effect on the mechanical and thermal properties of the composites. The tensile strength, e longation at break and impact strength for composites of 2% OREC are 62\^3%, 285 \^9% and 14\^0% higher than those of pure PP, respectively. The thermogravimetri c temperature of 10% weight lose of the composite sample is 50 K higher than th at of pure PP.
Keywords:Nano\|composites  Organic rectorite clay(OREC)  Pol ypropylene(PP)
