The flexible and rechargeable energy storage device with excellent performance is highly desired due to the demands of portable and wearable devices. Herein, by integrating the bendability and stretchability of Polyvinyl alcohol (PVA), pseudocapacitance of Polyaniline (PANI), and the charge transport ability of carbon nanotubes (CNTs), PVA/CNT/PANI flexible film was fabricated as supercapacitor electrodes with excellent electrochemical performance and flexibility. Full-solid supercapacitor is prepared based on PVA/H 2 SO 4 gel electrolyte and as-prepared film electrodes. The device achieves an areal capacitance of 196.5 mF cm -2 with high cycling stability. The flexible properties of PVA, the conductivity of CNT, and the pseudo-capacitance of PANI contribute to the superior performance. Present work develops a facile and effective way for preparing flexible electrode materials. Graphical Abstract In present work, we fabricated PVA/CNT/PANI flexible film as supercapacitor electrodes with excellent electrochemical performance and flexibility.

“…A. Alptekin et al [56] reported that CV curves of VACNT/PANI at different scan rates and found that area under the curve increases with the increasing the scan rates from 20 to 400 mV/s and oxidation peaks to be steady on the CV curve and its indicates resistance effects were not pronounced for the synthesized composite electrodes, otherwise CV curves shape from horizontal to diagonal. The specific capacitances (Cs) were first evaluated from CV using the equation [18]. The specific capacitance for starch-PANI electrode calculated using the CV curves was 499.5, 262.5 and 138.10 F/g at scan rates of 5, 10 and 20 mV/s respectively.…”

“…PANI and polypyrrole composites have been extensively explored for the supercapacitor electrode applications [1,16,17]. PANI was extensively used to prepare the composites with graphene [18], carbon nanotubes [19,20], carbon paper [21], gold [22], stainless steel [23], graphite [24,25], activated carbon [26] due to its easy synthesis and deposition. It is important to mention that PANI offers high pseudocapacitive performance.…”

The present study deals with the intensified synthesis of starchpolyaniline (starch-PANI) nanocomposite using an ultrasound-assisted method. Starch is a key component in this nanocomposite, which acts as a backbone of the nucleation of PANI. The Electrochemical property of the nanocomposite arises due to the addition of PANI. This is one of green approach for the synthesis of bio nanocomposite using ultrasound. The crystallinity of the composite is evaluated using the Scherrer Formula. The starch-PANI nanocomposite was characterized by XRD, FT-IR, Raman, XPS and TEM. The composite nanoparticles show spherical morphology. The elemental composition of starch-PANI showed O 1s peak at 546 eV, N 1s peak at 416 eV, C 1s peak at 286 eV and S 1s peak at 176 eV. The electrochemical studies of the starch-PANI electrodes are evaluated by cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS). Starch-PANI electrode has shown the maximum specific capacitance of 499.5 F/g at 5 mV/s scan rate.

We developed an efficient and environmentally friendly strategy for synthesizing an N-doped carbon aerogel by the carbonization of an alkaline peroxide mechanical pulp (APMP) fiber aerogel saturated with rhodamine B (RB) dyes. The APMP aerogel was prepared via cellulose extraction, sol-gel, and freeze drying. The resulting aerogel had a high adsorption capacity (250 mg g−1) and a fast adsorption rate (within 30 s) towards RB dyes. The saturated aerogel was used as a starting material for further carbonization to prepare N-doped carbon aerogels. SEM studies showed that the 3D network structure of the APMP aerogels was well preserved after RB adsorption and carbonization. The prepared carbon aerogel exhibited a graphitized structure, and N (2.15%) was doped at pyridinic N and pyrrolic N sites in the 3D carbon network. The specific capacitance of the N-doped carbon aerogel reached 185 F g−1 at a current density of 1 A g−1, which is higher than carbon aerogels (155 F g−1).
