Abstract

Polycarbonate obtained by solid state polycondensation (SSP) crystallizes in an orthorhombic configuration with a = 12.1 Å, b = 10.1 Å and c = 22.0 Å. Its morphology is of non-spherulitic lamellar type, while that of melt or solution crystallized commercial polycarbonate is distinctly spherulitic. These changes in crystalline structure and morphology can be explained, in the present case, on the basis of restricted mobility of the chains and the crystal growth in an extended chain configuration during the SSP step.

    Contrarily, the surface of PCexs (Fig. 11b) is rougher most probably because of the occurrence of crystallization induced by the solubilization/precipitation process. Similar structures were already reported for PC and attributed to spherulite growth [40,37]. For both nanocomposites (panels c and d in Fig. 11) no CNC aggregation was observed and then the filler seems to be homogeneously dispersed within the polymeric matrix.
