摘　　要：The demand for wearable electronics is still growing,and the rapid development of new electrochemical materials and manufacturing processes allows for innovative approaches to power these devices.Here,three-dimensional(3D)self-supported reduced graphene oxide/poly(3,4-ethylenedioxythiophene)(rGO/PEDOT)hybrid fiber fabrics are systematically designed and constructed via phase inversion-based microfluidic-fiber-spinning assembly(MFSA)method,followed by concentrated sulfuric acid treatment and chemical reduction.The rGO/PEDOT fiber fabrics demonstrate favorable flexibility,interconnected hierarchical network,large specific surface area,high charge storage capacity,and high electrical conductivity.In addition,the all-solid-state supercapacitor made of these rGO/PEDOT fiber fabrics proves large specific capacitance(1028.2 mF cm^(−2)),ultrahigh energy density(22.7μWh cm^(−2)),long-term cycling stability,and excellent flexibility(capacitance retention remains at 84%,after 5000 cycles of continuous deformation at 180o bending angles).Further considering those remarkable electrochemical properties,a wearable self-powered device with a sandwich-shaped supercapacitor(SC)is designed to impressively light up LEDs and power mini game console,suggesting its practical applications in flexible and portable smart electronics.
