Study of Structure of Polypropylene Microfibres Modified with Multi-Walled Carbon Nanotubes

The paper presented is concerned with studies of a supermolecular structure and its transformation during the process of drawing new composite microfibres obtained from isotactic polypropylene (iPP) – as a matrix and multi-walled carbon nanotubes (MWCNT) used as the filler. The nanostructure of iPP/MWCNT microfibres as spun and after drawing at a temperature of 95°C was investigated using scanning electron microscopy (SEM), wide angle X-ray scattering (WAXS), small angle X-ray scattering (SAXS) and differential scanning calorimetry (DSC) methods.
