Carbon nanotube/metal oxide dispersed poly(ortho‐aminophenol) as a ternary nanocomposite film: Facile electrosynthesis, surface characterization, and electrochemical pseudocapacitive performance

In this work, CNT‐NiCo2O4 was first synthesized via a chemical strategy in order to fabricate the ternary nanocomposite of a p‐type conductive polymer. Subsequently, hybrid poly(o‐aminophenol) POAP/CNT‐NiCo2O4 ternary composite films were prepared via the electropolymerization of POAP in the presenc...

Description
Summary:In this work, CNT‐NiCo2O4 was first synthesized via a chemical strategy in order to fabricate the ternary nanocomposite of a p‐type conductive polymer. Subsequently, hybrid poly(o‐aminophenol) POAP/CNT‐NiCo2O4 ternary composite films were prepared via the electropolymerization of POAP in the presence of CNT‐NiCo2O4 to be used in electrochemical storage devices as the active electrode. Electrochemical analyses including galvanostatic charge–discharge experiments, cyclic voltammetry, and electrochemical impedance spectroscopy were conducted to study the system performance. Furthermore, surface analyses were carried out to characterize the POAP/CNT‐NiCo2O4 composite film. Novel nanocomposite materials with the merits of extraordinarily high active surface area, ease of fabrication, and superior stability in aqueous electrolytes are presented for use in electrochemical redox capacitors.
