Characterization of multiwalled carbon nanotubes-PMMA composites

Abstract

We report, for the first time, preliminary results obtained from analysis of poly(methyl methacrylate) -multiwalled carbon nanotubes composites thin films. These films were prepared by mixing the polymer with different nanotube concentrations and were deposited by spin coating on glass substrates. The composites were characterized by Raman spectroscopy and scanning electron microscopy. The evolution of the conductivity versus the nanotube concentration was carried out in the order to determine the transport process in these materials. Such a composite is promising for use as transporting layer in multilayer diodes.
