| Abstract: | This account showed that nanometer-active calcium carbonate (CaCO3) improved polyamide 1010/organic montmorillonite (OMMT) composites and OMMT boosted polyamide 1010/CaCO3. The mechanical performance suggested the composites to be reinforced through adsorption forces present between the nanofillers and the matrix. The synergistic effect of CaCO3 and OMMT increased the yields and shrunk cavities when observed by scanning electron microscopy. The obvious resulting synergism was verified by X-ray scattering techniques after the addition of OMMT. The concentration of CaCO3 did not change lamellar-size or influence the crystal growth. The effect of CaCO3 on melting behavior was found less significant than that exert on crystallization behavior. |
