“…The peaks at 1239 and 1133 cm −1 are the CC stretching vibration peak of the quinone ring and the stretching vibration peak of the quinone nitrogen atom. The appearance of the peak at 813 cm −1 ascribe to the absorption of out‐of‐plane bending vibration of CH in the benzene ring 37–39 . Compared with the infrared spectrum of eigenstate polyaniline, it is found that the most significant change in the peak position after acid doping is the vibrational absorption peak of the quinoid nitrogen atom, which moves from 1152 to 1133 cm −1 , and the absorption peak also tends to strengthen.…”

“…The appearance of the peak at 813 cm −1 ascribe to the absorption of out-of-plane bending vibration of C H in the benzene ring. [37][38][39] Compared with the infrared spectrum of eigenstate polyaniline, it is found that the most significant change in the peak position after acid doping is the vibrational absorption peak of the quinoid nitrogen atom, which moves from 1152 to 1133 cm −1 , and the absorption peak also tends to strengthen. This phenomenon indicates that the doping mainly occurs on the quinoid nitrogen atom in PANI, rather than on the benzene nitrogen atom.…”

In previous studies, polyaniline nanofiber sensor on interdigital electrode is sensitive to light. Herein, we prepared a flexible hydrogel sensor with polyaniline nanofiber as the active material and polyacrylamide hydrogel as the flexible substrate. Comparing the properties of above two different kinds of sensors with polyaniline nanofiber, the photocurrent generated by PANIhydrogel sensor under external light stimulation is about 1~2 orders of magnitude higher than interdigital electrode sensor, indicating the PANI-hydrogel sensor is more sensitive. The two sensors can all respond to different wavelengths of monochromatic light, especially sensitive to light of smaller wavelengths such as ultraviolet light (380 nm) and blue light (475 nm). Moreover, the volt-ampere characteristic curve in response to external light stimulation can be clearly distinguished only when the appropriate concentration of proton acid is doped (3 g citric acid, 7 g acetic acid, and 3 ml HCl).

“…Pbp polymerize stepwise into the macromolecules and thus the degree of polymerization increases steadily. Deviating from the reaction conditions, either an unselective reaction occurred, or the conversion was too low [ 7 , 17 , 18 , 19 , 20 , 21 , 22 ]. The results of this study show good agreement with the previous studies reported for other similar conducting polymers [ 17 , 18 , 19 , 20 , 21 , 22 ].…”

“…CVs were obtained at 20–100 mV s −1 potential scan rates, whereas GCD curves were recorded at 0.5 to 5.0 A g −1 . From GCD, the gravimetric specific capacitance and coulomb efficiency ( η t ) in two-electrode setup were calculated by Equations (4) and (5), respectively [ 18 , 19 ]. C s = 4( I × ∆ t )/(∆ V × m ) η t = ( t d / t c ) × 100 where V d is the voltage drop (V), t d is discharge time (s), and t c is charging time (s).…”

Physical, Chemical, and Electrochemical Properties of Redox-Responsive Polybenzopyrrole as Electrode Material for Faradaic Energy Storage

et al. 2021

Polybenzopyrrole (Pbp) is an emerging candidate for electrochemical energy conversion and storage. There is a need to develop synthesis strategies for this class of polymers that can help improve its overall properties and make it as suitable for energy storage applications as other well-studied polymers in this substance class, such as polyaniline and polypyrrole. In this study, by synthesizing Pbp in surfactant-supported acidic medium, we were able to show that the physicochemical and electrochemical properties of Pbp-based electrodes are strongly influenced by the respective polymerization conditions. Through appropriate optimization of various reaction parameters, a significant enhancement of the thermal stability (up to 549.9 °C) and the electrochemical properties could be achieved. A maximum specific capacitance of 166.0 ± 2.0 F g−1 with an excellent cycle stability of 87% after 5000 cycles at a current density of 1 A g−1 was achieved. In addition, a particularly high-power density of 2.75 kW kg−1 was obtained for this polybenzopyrrole, having a gravimetric energy density of 17 Wh kg−1. The results show that polybenzopyrroles are suitable candidates to compete with other conducting polymers as electrode materials for next-generation Faradaic supercapacitors. In addition, the results of the current study can also be easily applied to other systems and used for adaptations or new syntheses of advanced hybrid/composite Pbp-based electrode materials.
