Polyaniline (PANI) is extensively utilized as the electrode material of supercapacitors. Nevertheless, its capacitive performance still unsatisfactory due to limited electrical conductivity, volume change during charging and discharging, buried active sites. In this paper, Ti3C2Tx supported cross-linked polyaniline nanorods (C-PANI/Ti3C2Tx) were prepared by in-situ polymerization aniline on nanosheets using triphenylamine (TPA) a crosslinking agent p-phenylenediamine (PPDA) chain extender. The crosslinked skeleton C-PANI nanosheet substrate improve conductivity composites, inhibit PANI, expose more sites facilitate electron/ion transport, thus endowing composites with excellent performance. C-PANI/Ti3C2Tx-4 exhibits specific capacitance 489.5 F/g at 1 A/g (409.5 even 20 A/g) retention 86.6% after 5000 cycles, which significantly better than some reported PANI-based composites. Electrochemical investigation has shown that contributes total charge reaction diffusion-controlled process. assembled flexible solid-state symmetric supercapacitor (FSSC) shows high energy/power output (28.6 Wh/kg 287.9 W/kg) bending Thus, PANI FSSC show great potential in wearable portable electronic devices.
