In this work, the binary nanocomposite of crosslinked polyaniline nanorods (CPANINRs) and molybdenum disulfide (MoS 2 ) is first synthesized by in situ polymerization, and CPANINRs/MoS 2 on functionalized carbon cloth (CPANINRs/MoS 2 /FCC) is facilely constructed by a drop-casting method. The composition, morphology, and structure of the CPANINRs, MoS 2 , and CPANINRs/MoS 2 binary nanocomposite are characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The electrochemical properties of the MoS 2 /FCC, CPANINRs/FCC, and CPANINRs/MoS 2 /FCC are tested by cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD). The experiment results show that the CPANINRs/MoS 2 /FCC exhibits excellent stability and high specific capacitance, and its specific capacitance reaches 618.75 F g −1 at a current density of 0.5 A g −1 . The CPANINRs/MoS 2 /FCC has a long cycling life and the capacity retention of 91.46% is obtained after 2000 cycles at a large current density of 10 A g −1 . Moreover, the CPANINRs/MoS 2 /FCC-based symmetric supercapacitor also exhibits excellent rate performance and good cycling stability. The specific capacitance based on the total mass of the two electrodes is 106.4 F g −1 at a current density of 0.5 A g −1 and the capacitance retention of 93.6% is obtained after 2000 cycles.
