In the present study, we introduce a simple chemical method to synthesize Zn-based MOF (Zn-BTC). The structural morphology and microstructure analysis of the synthesized materials were performed by Fourier transform infrared spectroscopy and powder X-ray diffraction (XRD), followed by scanning electron microscopy. The obtained Zn-BTC was decorated with poly orthoaminophenol film (POAP/Zn-BTC) through electropolymerization. The electrochemical behavior of composite electrode was studied using an acidic solution in three-electrode cyclic voltammetry and charge/discharge system. The POAP/ Zn-BTC composite electrode showed a specific capacitance of 580 F/g in a current density of 1 A/g. Our results provide an improved conductive polymer composite film with high active surface area, easy synthesis method, and high cycling stability for supercapacitors in aqueous electrolytes.
