▎ 摘　　要

Researchers have been focusing on the electrochemical energy storage system to tackle with the current energy crisis problem. With the increased demand of wearable electronics, all-solid-state flexible supercapacitors are becoming promising energy storage device. In this study, a simple and facile method was practiced to prepare hybrid composites by integrating molybdenum disulfide (MoS2) and graphene oxide (GO) as dual dopants to codope conducing polymer polyaniline (PANI), affording the PANI/MoS2/GO composite via in situ chemical oxidative polymerization. The as-prepared PANI/MoS2/GO composite was characterized by various spectroscopic methods, ranging from X-ray powder diffraction, infrared spectroscopy to scanning electron microscopy. The supercapacitive properties of the prepared dual dopant-doped composite as electrode materials have been evaluated electrochemically and yielded specific capacitance of 130.4 F/g under 1.0 A/g current density. Excellent rate performance was observed for the PANI/MoS2/GO composite, giving specific capacitance of 96.7 F/g with 10.0 A/g current density applied. The composite remained to give an excellent capacitance retention of 98.5 % after 500 galvanostatic charge-discharge cycles, which demonstrated the unique stabilizing effects of MoS2 and GO dual dopants toward PANI's energy storage behavior in terms of supercapactive performances. The findings in this study will contribute significantly to the progress of conducing polymer-based energy storage materials.
