“…The chemical doping is a reversible process which occurs by protonation in aqueous acid solution, with no changes on the number of electrons associated with the polymer chains, basically, consists of protons addition to the polymer chains of a doping agent, leading to the shift of electrons from π system [4] . Studies have shown that certain conducting polymers such as Polyaniline and Polypyrrole have been found to offer corrosion protection of iron, steel and aluminum, attributed to its high stability in the air, adhesion and redox properties with the substrate [5][6][7][8][9] .…”

SbstractThe rheological properties of acrylic paints and polyaniline (PAni) blends, with different contents of PAni doped by dodecyl benzene sulphonic acid (DBSA) and, dispersed by mechanical stirrer and ultrasonic, were investigated by controlled shear rate testing ramps. The results showed that the commercial acrylic paint had tended to deliver the required stability on the blends, in order to avoid sedimentation process. All samples exhibited non-Newtonian flow behavior (shear thinning), increasing PAni content the flow behavior index (n) decreased (0.41 to 0.11) and power law model were used to fitted the experimental curves. The results showed that the addition of PAni-DBSA affects the viscoelastic behavior of the mixtures due to the interactions between the components in the mixture. The best properties were obtained for samples 90/10 wt % dispersed by ultrasonic, indicating the feasibility of the usage as a conducting paint.

“…The peaks observed in the pattern are due to the stainless-steel substrate. Such an amorphous nature was observed for the polyaniline thin film synthesized by Joshi and Lokhande and Jamadade et al using electrodeposition method [9,26]. The inset of Figure 2 shows a photograph of a polyaniline thin film on a stainless-steel substrate.…”

We report the synthesis of polyaniline nanofibers using the successive ionic layer adsorption and reaction (SILAR) method. The structural study shows the amorphous nature of polyaniline. The formation of polyaniline nanofibers has been revealed by scanning electron microscopy (SEM) whereas the confirmation of polyaniline material is obtained from Fourier transform infrared (FT-IR) spectroscopy. A plausible explanation illustrating the growth mechanism is presented. A maximum specific capacitance of 1078 F.g −1 at a scan rate of 5 mV.s −1 is obtained. The charge-discharge behavior shows a maximum specific power of 1.2 kW.kg −1 and specific energy of 64 Wh.kg −1 . The ease of the synthesis and the interesting electrochemical properties indicate that polyaniline nanofibers are promising materials for supercapacitor applications.

“…The first range corresponds to C-C stretching vibrations of the quinonoid ring [36] where at 1602 cm -1 a peak in the green PANI is observed that is higher than the violet-blue PANI, in which only a plateau is observed. The position corresponds to the protonation of the polymer and the formation of semiquinoid rings [37], indicating the formation of the emeraldine structure.…”
