Comparison among Different Processing Conditions in Synthesis of Polypropylene/Carbon Nanotubes Composites Using Raman Spectroscopy

Abstract

This work presents a simple and rapid method for determining which of three combined processing conditions, rotation speed, mixing temperature and duration of mixing that is the most efficient for the preparation of polypropylene/carbon nanotube composites. For this purpose, polypropylene nanocomposites with a constant amount of carbon nanotubes (5.0 wt.%) and different processing conditions are examined through X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Raman Spectroscopy. The latter, Raman Spectroscopy, specializes in and reveals which processing condition among them is the most significant, in order to construct nanocomposites with good dispersion of nanotubes in the polymer matrix.
