摘要

Poly(5-cyanoindole)/carbon fiber composite material (P5CIn/CF) was prepared via a simpleelectrodeposition method. The CF core and the P5CIn shell formed a 3-D P5CIn/CF core/shellstructure composite. The P5CIn/CF was characterized by FT-IR spectroscopy, scanning electronmicroscope, cyclic voltammetry, electrochemical impedance spectroscope, and galvanostaticcharge/discharge techniques. The specific capacitance of P5CIn/CF was 302 F g at the scan rate of 1 A g . The assembled symmetric supercapacitor based on P5CIn/CF showed a specific capacitance of-1 -1 94 F g at 7.5 mV s and its energy density reached 16 Wh kg at the power density of 0.6 kW kg .Additionally, the capacitance retention of P5CIn/CF was 78% after 2000 cycles. These resultssuggested that the P5CIn/CF was a hopeful electrode material for the flexible supercapacitorsapplication.
