摘要:本研究通过浸渍原位聚合的方法,以天然植物纤维与吡咯为原料,制备聚吡咯(PPy)纸基柔性电极,并探讨了不同制备工艺条件(吡咯浸渍液浓度、浸渍次数、打浆度和植物纤维原料品种)对PPy纸基柔性电极的影响。结果表明,在最佳工艺条件(吡咯浸渍液浓度30%(体积分数)、浸渍次数2次、打浆度35 °SR)下漂白硫酸盐阔叶木浆纤维制备的PPy纸基柔性电极的电导率达9.83 S/cm,在5 mA/cm2电流密度下,面积比电容达1 934.66 mF/cm2。将其组装成固态超级电容器,表现出优异的电化学性能与柔性稳定性:5 mA/cm²电流密度下面积比电容达393.50 mF/cm²,1 000次充放电循环后电容保持率高,180°弯折500次后容量仅衰减9.1%。
Abstract:The study used natural plant fibers and pyrrole as raw materials, the polypyrrole-based paper flexible electrodes were fabricated via in-situ polymerization after impregnation. This study investigated the effects of various preparation parameters (pyrrole impregnation concentration, impregnation cycles, beating degree, and types of plant fibers) on polypyrrole-based paper flexible electrodes. The results showed that under the optimal preparation conditions (pyrrole impregnation concentration of 30% (volume fraction), impregnation times of 2, beating degree of 35 °SR), bleached kraft hardwood plup fiber prepared electrode achieved an electrical conductivity of 9.83 S/cm and an areal specific capacitance of 1 934.66 mF/cm² at a current density of 5 mA/cm². Solid-state supercapacitors were assembled using the obtained polypyrrole-based paper electrodes, which exhibited outstanding electrochemical performance and mechanical flexibility. The assembled device delivered an areal specific capacitance of 393.50 mF/cm² at 5 mA/cm², and maintained a high capacitance retention after 1 000 charge-discharge cycles. After 500 bending cycles at 180°, the capacitance only decayed by 9.1%. The devices met the application requirements of flexible energy storage systems and were promising for flexible supercapacitor applications.
