Nanocomposites based on functionalized nanotubes in polyaniline matrix by plasma polymerization

A co-spraying method of binary mixture aniline–single-walled nanotubes (SWNTs) in a plasma stream is proposed as an alternative to design new composites and nanotube functionalizing. The electrical characterizations, Fourier transform-infrared spectroscopy (FT-IR) and Raman spectra show a chemical bonding to the nanotube surface. I–V characteristics show a combined effect of the conduction mechanisms imposed by space charged limited currents (SLCS) and the metallic/semimetallic character of the nanotubes.
