In this study, 3D layered multicomponent nanohybrids were successfully prepared with the combinations of graphene, molybdenum disulfide (MoS2), and polyaniline (PANI). This process is a straightforward physical exfoliation method because any special, sophisticated chemical treatment was unnecessary. PANI contributed to the stability of the colloidal dispersion of the exfoliated graphene and MoS2 sheets in the solvent medium. Graphene/MoS2/PANI-solution nanohybrids, namely GMPNs exhibited a unique 3D layered structure and each layer affected each other, which resulted in unique electrical/electrochemical properties. In particular, GMPNs had an open porous structure that provided effective pathways for promoting redox reactions with electrolyte ions on the inner surfaces. Of the GMPN samples, the nanohybrid with a G:M:P weight ratio of 1:1:80 exhibited the excellent electrochemical properties and good long term cycling stability in acid and neutral solution. |
