Probing the presence and distribution of single-wall carbon nanotubes in polyvinylidene difluoride 1D nanocomposites by confocal Raman spectroscopy

Abstract

Novel single-wall carbon nanotubes/polyvinylidene difluoride one-dimensional nanorods, have been prepared via anodized alumina template by infiltration of the mixture at temperatures above the blend molten temperature. By combining X-ray diffraction and Raman spectroscopy techniques, the latter working on confocal mode, it has been shown, for the first time, the presence and distribution of carbon nanotubes all the way along the nanorod length, ∼50 μm. The maximum concentration of single-wall carbon nanotubes is found within the first 15 μm. These 1D nanostructured materials could have potential applications in electronic, optical, magnetic, and energy storage devices.
