ABSTRACT In this work, a polyaniline honeycomb nanocomposite is synthesized via chemical route and Breath Figure technique and characterized through Fourier Transform Infrared, X‐ray diffraction, thermogravmetric analysis, and morphological analysis (SEM and TEM). The DC, AC conductivities, and Mott's VRH parameters have been measured in the temperature range from 303 to 373 K and frequency range from 20 Hz to 1 MHz. The DC conductivity of the nanocomposite enhanced and AC‐conductivity is attributed to overlapping large polaron tunneling (OLPT) mechanism. The composite is tested for supercapacitor properties. A specific capacitance of 554 F/g and energy density of 76.9 Wh/kg at 1 A/g current density, and high power density of 2.00 kW/kg at 4 A/g indicates more feasibility of the redox process. Electrochemical impedance spectroscopy and cyclic voltammetry reveals that the nanocomposite is an excellent supercapacitor electrode material. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
