“…Aqueous dispersed conducting PANI nanofibers with acidic phosphate ester as dopant and a uniform thin diameter of 17-26 nm were used as electrode materials for supercapacitors.. 137 The specific capacitance of 160 F g −1 at a discharge rate of 0.4 A g −1 was higher than that of thick nanofibrous (120 F g −1 ) or spherical (90 F g −1 ) PANI, ascribed to its higher utilization of the active materials resulting from larger Brunauer-Emmett-Teller surface area of 70 m 2 g −1 . The high discharge-charge efficiency of 92% indicates that thin nanofibrous PANI possesses good electrochemical reversibility and discharge-charge rate-control capability.…”

“…Among the abovementioned supercapacitor materials, CPs-based pseudocapacitors, with their high-redox active capacitance, high conductivity and, most importantly, high intrinsic flexibility, have promised the most for high performance portable and flexible supercapacitor applications [22][23][24]. In recent development of CPs-based flexible ES applications, several approaches have been adopted to employ either the CPs alone [25][26][27][28] or composites of CPs with carbon materials [29][30][31][32][33][34][35][36][37] as the electrode materials. Here, in this review, we focus on the recent progress in the development of CPs and their composites for the development of flexible supercapacitors.…”

Flexible supercapacitors, a state-of-the-art material, have emerged with the potential to enable major advances in for cutting-edge electronic applications. Flexible supercapacitors are governed by the fundamentals standard for the conventional capacitors but provide high flexibility, high charge storage and low resistance of electro active materials to achieve high capacitance performance. Conducting polymers (CPs) are among the most potential pseudocapacitor materials for the foundation of flexible supercapacitors, motivating the existing energy storage devices toward the future advanced flexible electronic applications due to their high redox active-specific capacitance and inherent elastic polymeric nature. This review focuses on different types of CPs-based supercapacitor, the relevant fabrication methods and designing concepts. It describes recent developments and remaining challenges in this field, and its impact on the future direction of flexible supercapacitor materials and relevant device fabrications.

The e ect of CO 2 on the morphology of polyaniline (PANI) polymerized in the presence of compressed CO 2 was investigated. Two dissimilar morphologies, nanorods and nanoparticles, were successfully obtained using polymerization with and without compressed CO 2 . The obtained nanorods and particles were characterized by X-ray di raction (XRD), Fourier transform infrared spectroscopy (FT-IR), Brunauer, Emmett and Teller (BET) analysis, and scanning electron microscopy (SEM). FT-IR and XRD results showed the presence of polyaniline emeraldine salt form. The SEM images clearly showed PANI nanorods (PANNRs) and nanoparticles (PANNPs) in polymerized PANI. From SEM images, the average diameters of PANNPs and PANNRs were calculated to be 85 and 90 nm, respectively. BET analysis indicated the surface area of PANNRs to be 44% larger than that of the PANNPs. The adsorption performance of the prepared PANI was evaluated in a decolorization process of acid blue 25 dye (AB25). The PANNRs always showed better adsorption compared with PANNPs. The PANNRs recorded a higher decolorization rate, with 99.8% of the dye adsorbed within 8 min; whereas, PANNPs showed a rate of 99.38% decolorization in 16 min. The adsorption kinetics of both PANI were analyzed with both Freundlich and Langmuir models. As a result, the Langmuir isotherm model showed better agreement with the experimental data of the dye adsorption process than that of Freundlich model. Furthermore, it was found that the dye adsorption procedure onto the two fabricated PANI structures follows the pseudo-second-order model.
