Molybdenum disulfide/reduced graphene oxide/polyaniline ternary composites (MoS/rGO/PANI) were designed and synthesized by a facile two-step approach including hydrothermal and polymerization process. The MoS/rGO/PANI composites presented an interconnected 3D network architecture, in which PANI uniformly coated the outer surface of the MoS/rGO binary composite. The MoS/rGO/PANI composites with a weight percent of 80% (MGP-80) exhibits the best specific capacitance (570 F g at 1 A g) and cycling stabilities (78.6% retained capacitance after 500 cycles at 1 A g). The excellent electrochemical capacitive performance is attributed to its 3D network structure and the synergistic effects among the three components that make the composites obtain both pseudocapacitance and double-layer capacitance.
通过包括水热和聚合过程的简便两步法设计并合成了二硫化钼/还原氧化石墨烯/聚苯胺三元复合材料（MoS₂/rGO/PANI）。MoS₂/rGO/PANI复合材料呈现出相互连接的三维网络结构，其中聚苯胺均匀地包覆在MoS₂/rGO二元复合材料的外表面。重量百分比为80%的MoS₂/rGO/PANI复合材料（MGP-80）表现出最佳的比电容（在1 A g⁻¹时为570 F g⁻¹）和循环稳定性（在1 A g⁻¹下500次循环后电容保持率为78.6%）。优异的电化学电容性能归因于其三维网络结构以及三种组分之间的协同效应，使得复合材料同时获得赝电容和双电层电容。
