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.
