The structure and properties of these June 20 2017 composites have been investigated by FTIR SEM TEM XRD UV DSC and TGA. The Accepted July 4 2017 formation of Poly MWCNT Amide composites was confirmed and the DC electrical Available online conductivity of poly-composites was in the range 10-6 S cm due to the interaction July 5 2017 between the nanotubes.
