In this paper, using a low-cost paper fiber (PF) as a substrate, eigenstate polyaniline–coated PFs with graphene (GO/PANI/PF) ternary materials were synthesized by using the chemical oxidative polymerization method. Electrochemical measurements showed that the GO/PANI/PF electrode exhibited an excellent electrochemical performance compared with the PANI electrode. By adjusting the ratio of PANI and PF, the as-prepared GO/PANI/PF–2.5% electrode exhibited the highest specific capacitance 937 F g⁻¹ at current density 1 A g⁻¹ in a 0.5 M H₂SO₄ aqueous solution, and 74.5% retention of initial capacitance after 2000 charge–discharge cycles at 5 A g⁻¹. The symmetric capacitor on the basis of GO/PANI/PF nanocomposite delivers a superior energy density of 10.12 Wh kg⁻¹ at 456 W kg⁻¹ at a current density of 1 A g⁻¹.

在本文中，以低成本纸纤维（PF）为基材，通过化学氧化聚合方法合成了石墨烯（GO / PANI / PF）三元材料的本征态聚苯胺涂层PF。电化学测量表明，与PANI电极相比，GO / PANI / PF电极表现出优异的电化学性能。通过调节PANI和PF的比例，所制备的GO / PANI / PF–2.5％电极在0.5 MH ₂ SO ₄水溶液中的电流密度1 A g ^-1下表现出最高的比电容937 F g ^-1，在5 A g ^-1下进行2000次充放电循环后，初始电容的保留率为74.5％。基于GO / PANI / PF纳米复合材料的对称电容器在456 W kg ^-1的电流密度为1 A g ^-1时可提供10.12 Wh kg ^-1的优异能量密度。
