Article Preview

Poly(L-lactic acid)-co-bisphenol-A epoxy resin/vermiculite nanocomposites(PLLA-co-bis A /VMT)were prepared by in-situ melt polycondensation of L-LA in the presence of amino-modified vermiculite. The fourier transform infrared (FTIR) spectra were used to investigate molecular interactions between the modified vermiculite and PLLA. The detailed thermal property and crystallization behavior of samples were studied by using polarized optical microscopy (POM), differential scanning calorimetry (DSC) and thermogravimetric analyzer (TGA). The result indicated that the thermal stability, overall crystallization rate and spherulitic texture of PLLA-co-bis A were strongly influenced in the presence of vermiculite particles.
