“…Under red laser illumination, PPy films doped with polystyrene sulfonate exhibits higher conductivity compared with PPy films doped with NSA, at 0.3 and 0.5 V, respectively. Additionally, PPy film conductivity deposited under red laser illumination is higher than that of PPy films deposited under Xe illumination 60 …”

Polypyrrole (PPy) has unique features such as easy synthesis, environmental stability, and high electrical conductivity (approximately 105 S/cm and even >380 S/cm) for bulk and thin‐film materials. Thus, PPy is applied in numerous well‐established applications, such as in sensors, supercapacitors, and resonators. These applications take advantage of the unique properties achieved through the structure and properties of PPy. This article comprehensively elaborates the methods used to synthesize conductive PPy, along with the important factors affecting its conductivity. Emphasis is given to versatile and basic approaches that enable control of the microstructural features that eventually determine PPy conductivity. Despite the intensive research in this area, no previous study has presented all possible relevant information about PPy fabrication and the important factors influencing its electrical conductivity.

“…The PPy/PB nano electrode presented enhanced electrochemical features such as good stability over continuous cycling and sensitivity towards reduction of H 2 O 2 . Similarly, a smoother film deposit with a distinct voltammetric behavior was obtained in the case of Ppy/DBS electrodes under sonochemical conditions [ 38 ]. It was also observed that the use of ultrasound facilitated the charge-transfer process at the Ppy/electrolyte interface and resulted in different charge distribution, explained by different amounts of intercalated DBS anions.…”

“…The effect of ultrasound amplitude on the formation of poly(pyrrole) PPy/Prussian blue (PB) and poly(pyrrole) Ppy/dodecylbenzenosulphonate (DBS) nanocomposites was investigated by Hostert et al [ 37 , 38 ] ( Table 1 , Entries 14 and 15). The following amplitudes of ultrasonic horn (20 kHz, 130 W) were checked at: 20%, 40%, and 60%.…”

This short review provides the current state-of-the-art of in situ coupling of ultrasound to chemical deposition methods. Synergetic action of ultrasound and light radiation or electrical fields may result in new powerful methodologies, which include sonophotodeposition and sonoelectrodeposition processes. The effect of ultrasound is explained on the basis of different physical mechanisms emerging from cavitation phenomenon. Some possible mechanisms of the interactions between ultrasound and photochemical and electrochemical processes are discussed here. The application of sonophotodeposition and sonoelectrodeposition as green energy sources in the syntheses of different nanomaterials is also reviewed.

“…Due to the easier oxidation of the pyrrole monomer and the easier formation of its cation radical, the PPy synthesis peak shifts to more negative potentials. 19,20 In the PPy synthesis voltammogram, in the forward scan, a configuration state was observed which disappeared on the reverse scan; it was reported that the peak is related to the impurities of the composite bed. 21,22 Fig .…”

Ferric Reducing Antioxidant Power (FRAP) assay is a measure of assessment of the total antioxidant power of compounds. In this study, the ability of homo and copolymer of Aniline (Ani) and Pyrrole (Py) to act as an antioxidant on ferric ion reduction is investigated. The oxidative homo and copolymerization on composite 2B pencil graphite were accomplished in citric acid medium containing calcium chloride (CaCl 2) as the supporting electrolyte by cyclic voltammetry method. The morphology and structural analysis of homo and copolymer was confirmed by SEM and FTIR. The FTIR and UV-visible spectra indicated that the increase of aniline monomer in the copolymer chain enhances the ferric ion reduction ability. The electrochemical impedance spectroscopy (EIS) is used for further investigation. It was revealed that the increase of aniline ring in polymeric chain decreased the charge transfer resistance (Rct) and thus increases the reduction effect and improved the free radical scavenging activity of copolymers.
