摘　　要：Flexible PANI-Polyethersulfone (PES) fibers were fabricated using the wet-spinning technique.PANI particles were uniformly distributed within the matrix and micropores formed by the phase separation of PES,which prevented PANI particles aggregation and facilitated the formation of continuous ion transport channels.The experimental results reveals that the electrochemical performance of the fiber electrode material is optimal when the concentration of PES in the spinning solution is 15wt%.The assembled supercapacitor exhibits a commendable specific area capacitance of 162.75 mF·cm^(-2) at a current density of 0.5 mA·cm^(-2) and achieves an energy density of 14.47 mWh·cm^(-2) at a power density of 321.69 mW·cm^(-2).The capacitor retains 98.1% of its capacitance after 1 000 bending cycles.Therefore,the prepared fibers have good electrochemical properties and flexibility,and this simple and efficient preparation method is promising for the scalable production of flexible electrodes.
