Abstract
A variety of semicrystalline isotactic polypropylene composites containing carbon nanotubes and nanofibers were produced by melt and solution techniques. The effect of the nanofillers on the crystallization process was investigated by transmission electron microscopy, scanning electron microscopy, and differential scanning calorimetry. Under the processing conditions applied in this study, the surfaces of the carbon nanomaterials act as nucleation sites in bulk samples and highly oriented composite films. This conclusion is confirmed by the calculation of Avrami exponents and, in particular, by direct microscopy evidence.
