“…In the case of PANI, it exists in different oxidation forms built from the repeating unit of benzenoid and quinoid [10]. The oxidation level varies from the fully oxidized form to reduced form classified based on the degree of polymerization [11]. Depending on the degree of polymerization, PANI appears in leuoemeraldine base (LEB), perningraniline base (PAB), and emeraldine base (EB) forms [12].…”

Poly(3,4-ethylenedioxyhiophene) (PEDOT), polyaniline (PANI), and polypyrrole (PPy) were prepared on indium tin oxide (ITO) substrate via potentiostatic from aqueous solutions containing monomer and lithium perchlorate. The concentration of monomers was varied between 1 and 10 mM. The effects of monomer concentration on the polymers formation were investigated and compared by using Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) measurements. FTIR and Raman spectra showed no changes in the peaks upon the increment of the concentration. Based on the SEM images, the increment in monomer concentration gives significant effect on morphologies and eventually affects the electrochemical properties. PEDOT electrodeposited from 10 mM solution showed excellent electrochemical properties with the highest specific capacitance value of 12.8 mF/cm 2 .

“…The FT-IR spectrum of the de-doped PANI is in good accordance with the previous reports, showing absorbance peaks at approximately 1585 cm À1 , 1496 cm À1 , 1308 cm À1 , 1155 cm À1 and 827 cm À1 , which were ascribed to the CQC stretching vibration of quinoid ring, CQC stretching vibration of benzenoid ring, C-N stretching vibration, C-H (in-plane) vibration of quinoid ring and C-H (out-of-plane) bending of benzene ring, respectively. [40][41][42][43] Interestingly, the C-N stretching vibration showed a red shift from 1308 cm À1 for neat PANI to 1304 and 1297 cm À1 for PANI in the binary composites of a-CNT (50%)/PANI (50%), and a-CNT (70%)/PANI (30%), respectively. The red-shift of the C-N vibration indicates longer electron delocalization along the C-N bond, suggesting better electrical conduction for the higher a-CNT content composites.…”

In the present work, we report the fabrication of high-performance thermoelectric materials using TiO2/CNT/PANI ternary composites. We showed that a conductivity of ∼2730 S cm-1 can be achieved for the binary CNT (70%)/PANI (30%) composite, which is the highest recorded value for the reported CNT/PANI composites. We further demonstrated that the Seebeck coefficient of CNT/PANI composites could be enhanced by incorporating TiO2 nanoparticles into the binary CNT/PANI composites, which could be attributed to lower carrier density and the energy scattering of low-energy carriers at the interfaces of TiO2/a-CNT and TiO2/PANI. The resulting TiO2/a-CNT/PANI ternary system exhibits a higher Seebeck coefficient and enhanced thermoelectric power. Further optimization of the thermoelectric power was achieved by water treatment and by tuning the processing temperature. A high thermoelectric power factor of 114.5 μW mK-2 was obtained for the ternary composite of 30% TiO2/70% (a-CNT (70%)/PANI (30%)), which is the highest reported value among the reported PANI based ternary composites. The improvement of thermoelectric performance by incorporation of TiO2 suggests a promising approach to enhance power factor of organic thermoelectric materials by judicial tuning of the carrier concentration and electrical conductivity.

“…Camphor sulfonic acid (CSA) with thin films of PANI doped on simple glass is prepared with the chemical polymerization method and rotated with a spin coater [ 65 ]. The adhesion efficacy of the thin film to the glass is excellent because of organic solvent and unpleasant organic matter, whereas the FTIR results showed the existence of dopant and change in their molecular structure for the thin film by an extraordinary CSA extraction fraction (1:8).…”

Polyaniline (PANI) is a famous conductive polymer, and it has received tremendous consideration from researchers in the field of nanotechnology for the improvement of sensors, optoelectronic devices, and photonic devices. PANI is doped easily by different acids and dopants because of its easy synthesis and remarkable environmental stability. This review focuses on different preparation processes of PANI thin film by chemical and physical methods. Several features of PANI thin films, such as their magnetic, redox, and antioxidant, anti-corrosion, and electrical and sensing properties, are discussed in this review. PANI is a highly conductive polymer. Given its unique properties, easy synthesis, low cost, and high environmental stability in various applications such as electronics, drugs, and anti-corrosion materials, it has attracted extensive attention. The most important PANI applications are briefly reviewed at the end of this review.
