SWNTs coated by conducting polyaniline: Synthesis and modified properties

Conducting polyaniline (PaN) was synthesized onto single-wall carbon nanotubes (SWNTs) by using the in situ polymerization method. Elemental analysis (EA), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR), field emission scanning electron microscope (FE-SEM), thermal gravimetric analysis (TGA), electron spin resonance (ESR), X-ray diffraction (XRD) and transmission electron microscope (TEM) were used to characterize the resulting complex nanotubes (SWNTs-PaN) structure. We observed no significant interaction chemically between the PaN and SWNTs. The physical properties of the complex nanotubes were measured and also showed that the SWNTs were modified by conducting polyaniline. (C) 2005 Elsevier B.V. All rights reserved.
