Abstract An efficient method for synthesis of polyaniline wrapped graphene aerogel/silver nanoparticles (PANi/rGA/AgNPs) has been successfully developed via a facile in situ one-pot hydrothermal method. The synergistic effect of the large surface area of rGA simultaneously with the high redox reaction of AgNPs and PANi, constituting a unique micro-nano framework structure, possesses the beneficial to rate capability and cycle stability. The assembled solid-state supercapacitors of PANi wrapped rGA/AgNPs can endow the specific capacitance of 365.14 F g−1 at 0.5 A g−1 and a high capacity retention of 88% after 4000 cycles at 1 A g−1.

用于固态超级电容器设备的聚苯胺包裹石墨烯气凝胶/银纳米粒子复合材料的一锅法合成

摘要 通过一种简便的原位一锅水热法成功地开发了一种合成聚苯胺包裹的石墨烯气凝胶/银纳米粒子（PANi/rGA/AgNPs）的有效方法。rGA的大表面积与AgNPs和PANi的高氧化还原反应的协同作用，构成了独特的微纳米骨架结构，有利于倍率性能和循环稳定性。由PANi包裹的rGA/AgNPs组装的固态超级电容器可以在0.5 A g-1下提供365.14 F g-1的比电容和在1 A g-1下4000次循环后具有88%的高容量保持率。
