Conducting polymers are usually good candidates for electrode materials of supercapacitors in spite of their lower cyclic stability, which can further be improved by combining with suitable nanofillers. In this work, we report the synthesis of nanocomposites of polyaniline (PANI), with equal weight% of graphene (G) and MoS₂, prepared via in-situ oxidative polymerization of PANI, along with PANI-G binary nanocomposites. The morphological analysis confirms the formation of well-dispersed composite materials, and the ternary composite appears to be an interlayered structure of graphene and MoS₂, encapsulating the PANI nanorods. As a result, the ternary composite exhibits an excellent supercapacitance behavior, suitable for energy storage applications as revealed by an enhanced cyclic stability. The ternary composite PANI-G-MoS₂ symmetric electrode measurement exhibits a remarkably high specific capacitance (C_s, 142.30 F g⁻¹) over binary composites under galvanostatic charge-discharge (GCD) cycles. The improved cyclic stability has contributed significantly in recovering the capacitance retention as high as 98.11% in comparison with pure PANI (∼40%) and binary composites (∼60–96%). Further, PANI-G-MoS₂ symmetric electrode (viz., based on two electrode measurement) exhibits a high energy density (2.65 Wh kg⁻¹) at a power density of 119.21 W kg⁻¹, which is attributed to the high charge transport phenomenon occurs at the interfacial region between electrodes and electrolyte.

尽管导电聚合物的循环稳定性较低，但通常仍是超级电容器电极材料的良好候选材料，可以通过与合适的纳米填料结合使用来进一步提高导电性。在这项工作中，我们报告聚苯胺（PANI）的纳米复合材料的合成中，用石墨烯（G）和MoS的相等重量％₂，通过制备原位PANI的氧化聚合，与PANI-G二进制纳米复合材料沿。形态分析证实形成了分散良好的复合材料，并且三元复合物似乎是石墨烯和MoS ₂的夹层结构。，封装了PANI纳米棒。结果，该三元复合材料表现出优异的超电容性能，如增强的循环稳定性所揭示，适用于能量存储应用。三元复合物PANI-G-MoS ₂对称电极的测量在恒电流充放电（GCD）循环下，相对于二元复合物表现出非常高的比电容（C _s，142.30 F g ^-1）。与纯PANI（〜40％）和二元复合材料（〜60-96％）相比，改善的循环稳定性显着有助于恢复高达98.11％的电容保持率。此外，PANI-G-MoS ₂对称电极（基于两个电极的测量结果）显示出高能量密度（2.65 Wh kg ^-1）在119.21 W kg ^-1的功率密度下，这归因于在电极和电解质之间的界面区域处发生的高电荷传输现象。
