Tubular composite of doped polyaniline with multi-walled carbon nanotubes

Thermal diffusivity measurements in PANI and PANI-MWNT composites using photo acoustic technique

“…All the characteristic Raman frequencies of PANI (HCl) and PANI (HCl)-MWNT composite are observed in the spectra [8][9][10]. The characteristic D-mode and G-mode vibrations of MWNT are observed in the composite at 1574cm -1 and 1345cm -1 respectively, confirming the formation of the composite.…”

“…The synthesis procedure of HCl doped PANI has already been reported [8][9]. PANI (HCl)-MWNT composites were synthesized by adding MWNT to aniline dissolved in HCl, under continuous stirring, with all other conditions remaining the same.…”

Polyaniline doped with orthophosphoric acid—A material with prospects for optoelectronic applications

“…This is strongly supported by the fact that the increase in crystallanity of the three PANI samples is in the ascending order of the size of the dopant ion attached. The graphite-like diffraction peak at around 25 • [13] is common to all the samples and is characteristic of the extent of pi conjugation in PANI.…”

An efficient route towards the covalent functionalization of single walled carbon nanotubes

“…The amine bonding alters the UV-vis spectra with the appearance of two new absorption peaks at 260 and 370 nm, respectively, which could be attributed to the p-p * (K band) transitions due to the covalent modifications with aniline. The formation of polymer of aniline has been ruled out, since UV-vis spectrum reveals the absence of the peaks corresponding to the benzenoid and quinoid segments of the polyemeraldine chain [21,22].
