中文摘要	An efficient approach to composite film fabrication that involves the control of doping processes between soluble multiwalled nanotubes (s-MWNTs) and polyaniline (PAN) molecules has been developed in this work. The s-MWNTs were prepared by introducing carboxylic acid and sulfonic acid groups to the surfaces of nanotubes. The s-MWNT was used as a dopant to react with the imine nitrogens of emeraldine PAN via the protonation doping process in a layer-by-layer manner. The resultant composite films on the quartz substrates were characterized by UV/V is spectroscopy, photoluminescence, Fourier-transform infrared spectroscopy, scanning electron micrograph and X-ray diffraction. Results showed that s-MWNTs were doped into polyaniline layers, which caused changes in the composite film characteristics such as electrical properties, spectroscopic features and morphology. Unlike the already-used layer-by-layer process based on electrostatic attraction, our process is based on the acid-base reaction between emeraldine and s-MWNT. Owing to the protonation doping, the bond between the carboxyl group and the imine nitrogen group becomes covalent, which enhances the stability of the film.
