Present work demonstrates the synthesis of novel poly(1-naphthylamine)-graphene oxide (PNA–GO) nanocomposites by the polymerization of NA in GO dispersion. Here, GO was synthesized by greener oxidation of graphite without using sodium nitrate. The characterization of PNA–GO nanocomposites by different analytical techniques indicates that structural, thermal, and electrochemical properties are dependent on GO content. Observation of interconnected fibrous arrangement of PNA in PNA–GO nanocomposites suggests the templating interaction of GO on PNA. Electrochemical studies reveal the improvement in capacitance, cyclic stability, and charge transfer characteristics of PNA–GO nanocomposite offering a low-cost and highly processable electrode material.
