Cotton fabric (CF) fabricated by natural cellulose fibers has porous structure and abundant hydrophilic hydroxyl groups, which is a promising substrate for flexible fabric-based supercapacitors. Graphene oxide (GO) nanosheets were fixed on the CF by vacuum filtration, and then the pyrrole monomers and silver ions (Ag+) were adsorbed to the surface of GO/CF by π-π and electrostatic interactions, respectively. Polypyrrole/silver (PPy/Ag) nanoparticles were in situ generated on the surface of GO/CF via UV-induced polymerization, forming the flexible PPy/Ag/GO/CF electrodes. The electrodes combine three active materials (PPy, Ag and GO) show good electrochemical performance. The electrode prepared under optimum conditions (UV irradiation time: 120 min; mass loading of GO on the CF: 3 mg cm−2) exhibits a high specific capacitance of 1664.0 mF cm−2). The flexible symmetric quasi-solid-state fabric-based supercapacitor (QFSC) based on the optimum electrode also keeps superior electrochemical performance and excellent mechanical flexibility, which is expected to have great application prospect for wearable energy storage devices.
