Abstract

Nylon1010/montmorillonite(MMT) nanocomposites were prepared by melt blending the polymer with MMT modified by metacresol(MC), nylon66 salt(NS), cetyl trimethyl ammonium bromide(CTAB)/MC, CTAB/NS respectively. TG and WAXD results show that MMT modified by co-intercalating agents has more larger interlamellar spacing and higher thermal decomposition temperature. In comparison with pure nylon1010 the tensile properties, over-all properties of nanocomposites are improved significantly. The adding of MMT changes possiblely the crystal structure of nylon1010 and raised the crystallizing temperature. The functions of two constituents of co-intercalating agents are different. CTAB benefits the extension of the interlamellar spacing of MMT, while MC and NS improve the compatibility of MMT and nylon matrix.
