“…The results are consistent with those in literatures. 22,23 The PANI synthesized with ethanol has three similar absorption peaks with that of the PANI without ethanol. It is interesting to note that by increasing the ethanol/ aniline volume ratio, the polaron band exhibits a bathochromic shift and appears at the higher wavelength when compared with that of PANI without ethanol (curve a).…”

ABSTRACT:The nanothread of polyaniline (PANI) using ammonium persulphate ((NH 4 ) 2 S 2 O 8 ) as an oxidant was prepared. The solution is composed of 0.4 mol dm Ϫ3 aniline, 1.0 mol dm Ϫ3 hydrochloric acid, and different proportions ethanol. The resulting products were characterized using infrared spectroscopy, UV-vis spectra, transmission electron microscope, thermogravimetric analysis techniques, and Xray diffraction. The experimental results show that the content of ethanol has effects on the morphology of PANI, but the effects on the conductivity are not very obvious. When the volume ratio of ethanol to aniline is 1:2, the more uniform and regular PANI nanothread can be prepared.

“…The appearance of broad peaks in PANI-DP may be attributed to the residual ordered DBSA after doping. 28,29 This is suggesting some differences in the composition of the samples. As evidenced by SEM images this may be due to some kind of interaction may be physical or chemical in the complex anilinium-DBSA under the condition obtained by the use of two different oxidants.…”

Two types of nano composite were obtained by in situ chemical method in polyaniline (PANI)/dodecylbenzenesulfonic acid (DBSA) system depending on the use of either ammonium persulfate (APS) or ferric chloride (FeCl 3 ) as the oxidant. In order to study the difference of the two composites in the surface characteristics, thermal stability, and electric properties, the composite films were studied by transmission electron microscopy (TEM), Xray diffraction (XRD), thermogravimetric analysis (TGA), and temperature dependent DC electrical conductivity. The results revealed a large difference in the surface morphology, thermal stability, and the microstructure properties between the two composites, and these differences were considered responsible for the molecular order and conductivity.

“…Finally, solubility of conducting polymers has always been a matter of discussion and many reports have been published in the literature discussing of solubility of PANI. [21][22][23] We have recently reported several methods for synthesis of water-soluble polyaniline. For example, Nabid 24 reported an enzymatic method for the synthesis of a water-soluble conducting poly (o-toluidine) (POT) in the presence of sulfonated polystyrene (SPS) as template.…”

Polyaniline-graft-Poly(N-isopropylacrylamide) copolymers were synthesized by atom-transfer radical polymerization (ATRP) of N-isopropylacrylamide using polyaniline macro-initiators. Polyaniline-chloroacetylchloride and polyaniline-chloropropionylchloride macroinitiators were obtained by the reaction of amine nitrogens of polyaniline with chloroacetyl chloride and 2-choloropropionyl choloride, respectively. Both macroinitiators and graft copolymers were characterized by FT-IR and 1 H-NMR spectroscopy. The cyclic voltammetry (CV) and UV-Vis spectroscopy studies showed that these copolymers are electroactive. The solubility test revealed that the polyaniline-graft-poly (N-isopropylacrylamide) copolymers are water soluble or water/methanol soluble. The Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) images showed the growing of poly (N-isopropylacrylamide) chains on polyaniline backbone. Investigation of thermal behavior of graft copolymers by thermal gravimetry analysis (TGA) confirmed the results obtained from AFM and SEM images.
