Summary In this study, we followed a facile method to grow well‐aligned PANI nanostructures on S‐doped reduced graphene oxide nanosheets (SPANI/S‐rGO) using hydrothermal method combined with soft template polymerization of aniline where naphthalene sulfonic acid is used as a dopant for PANI as well as the soft template. The effect of using different wt% of S‐rGO on the structural, morphology, and electrochemical performance of SPANI/S‐rGO composites has been evaluated. Supercapacitor fabricated using SPANI/S‐rGO10 (10 wt% of S‐rGO) composite based electrodes delivered a high specific capacitance of 347.5 F/g at a current density of 1 A/g in symmetrical cell design (the specific capacitance was calculated based on a single electrode). Only 11% of its initial capacitance is lost after 2500 cycles at a current density of 2 A/g. The enhanced performance is attributed to the optimum loading of S‐rGO in designing binary composite, well‐aligned growth of SPANI nanostructures on S‐rGO sheets, and synergistic effect of both S‐rGO and SPANI. The facile synthesized SPANI/S‐rGO composite electrode material with the aforementioned features is considered to be a promising candidate for a high‐performance supercapacitor.

“…Electrodes, as one of the components of a supercapacitor (electrodes, separator, electrolyte, current collector, and packing shell), seem to have a considerable impact on the electrochemical performance of the capacitor. Thus, various electrode materials, including activated carbon, [121][122][123][124] CNTs, 117,125,126 CNFs, [127][128][129][130] graphene, 76,[131][132][133][134] and MOFs, [135][136][137][138] have been developed. Xu and co-workers reported that excellent mechanical properties were obtained for conductive metal-organic framework (c-MOF) nanolayers on cellulose nanobers (CNFs), with hierarchical micro-mesoporosity, serving as electrodes in a foldable supercapacitor.…”

In this study, magnetron sputtering is implemented to adjust the sputtering power from 156 to 306 W at room temperature, and thin film samples of indium tin oxide (ITO) on a flexible fluorphlogopite substrate are taken. With the increase in power, the resistivity of the film first decreases and then increases. The resistivity is at least 1.51 × 10–3 Ω cm at 276 W, and the highest resistivity is 2.93 × 10–2 Ω cm at 156 W. The average light transmittance of the film (400–800 nm) decreases with the increase in power within the range of 156–276 W, The highest average transmittance is 92.6% at 156 W. The quality factor of the film first rises and then decreases as the power increases, it is as high as 4.47 × 10–3 Ω–1sq at 276 W. All the AFMs show that the roughness of the sample does not significantly change with power. The SEM picture shows that as the power increases from 156 to 276 W, the grain size increases slightly. All samples are bent 1200 times around a steel cylinder, and the sheet resistance does not change more than 5%.
