Flexible supercapacitors are attracting interest in wearable technologies as they can withstand mechanical deformations while delivering their energy storage function. Among frequently investigated electrode materials for flexible supercapacitors, polyaniline/graphene composites are favorable due to their synergistic properties that assure excellent specific capacitance, cycling stability, and high rate capability. This review highlights recent strategies to advance structural designs and synthesis methods of polyaniline/ graphene electrodes for flexible supercapacitors. Firstly, the general mechanism and feature of the flexible supercapacitor will be discussed, followed by current challenges that focus on two key aspects, structural design and synthesis of the electrode. Next, by sorting the composites based on their morphological dimensionalities (i. e., one-, two-, and threedimensional), and focusing the discussion on the two key aspects, we evaluate recent and effective strategies to develop flexible supercapacitors with polyaniline/graphene composite electrode. Finally, future perspectives are given for broader applications of the flexible supercapacitors.

Summary In this study, excellent performance and wide operating voltage are obtained with an aqueous electrolyte. Aqueous electrolytes are attracted more attention than other electrolytes (such as organic solvents, ionic liquids) in supercapacitor applications because of their safety, low cost, nontoxicity. Polypyrrole (PPy), aniline 2‐sulfonic acid (ASA) modified electrodes are hydrothermal synthesized on carbon felt (CFt) for supercapacitor applications. We investigate the presence of the concentration of ASA on the polymerization of the PPy. Furthermore, a high operating voltage of 3.0 V asymmetric supercapacitor (ASC) with graphite plate is assembled 3 M KCI. CFt/PPy/ASA(0.02)//GP exhibits a high specific capacitance value of 902.9 F g−1 at 5 mV s−1 and after 5000 cycle‐life testing 93.6% capacitance retention at a scan rate of 1000 mV s−1. The assembled ASC has an ultrahigh‐energy density of 1005 Wh kg−1 while delivering a power density of 3000 W kg−1 at a current density of 2 A g−1. The effect of ASA concentration on the supercapacitor performance has been observed.

“…However, these methods will cause delamination between the conductive layer and elastic substrate in sensors due to the weak binding force of different materials, which will seriously affect the stability and service life of sensors [6,7]. In addition, the conductive composites based aerogel or hydrogel using intrinsically conductive polymers such as polyacetylene [8], polythiophene [9,10], polypyrrole (PPy) [11,12] have been widely studied in past decade. It should be noted that these materials have several disadvantages, including poor elongation properties and complex preparation method.…”

The flexible wearable sensors with excellent stretchability, high sensitivity and good biocompatibility are significantly required for continuously physical condition tracking in health management and rehabilitation monitoring. Herein, we present a high-performance wearable sensor. The sensor is prepared with nanocomposite hydrogel by using silk fibroin (SF), polyacrylamide (PAM), polydopamine (PDA) and graphene oxide (GO). It can be used to monitor body motions (including large-scale and small-scale motions) as well as human electrophysiological (ECG) signals with high sensitivity, wide sensing range, and fast response time. Therefore, the proposed sensor is promising in the fields of rehabilitation, motion monitoring and disease diagnosis.
