Carbon-polyaniline coaxial structures for enhanced charge transfer and capacitance in supercapacitors.

ABSTRACT: Polyaniline (PANI) is widely used as a pseudocapacitive material in supercapacitors. However, PANI exhibits limited capacitance due to its poor electrical conductivity and low specific surface area. In this study, coaxial structures composed of silver nanowires (AgNWs) as the core, subsequently deposited with a carbon layer and PANI nanowires via in situ polymerization, were fabricated. Scanning electron microscopy revealed that the structures had an average diameter of 181 ± 57 nm and a length of 1.2 ± 0.6 μm. X-ray photoelectron spectroscopy analysis verified the successful formation of PANI on the outer layer of the structures, with fully benzenoid units and protonated amines. Raman spectra confirmed the deposition of sp²-hybridized carbon layers on the AgNW cores. Ele
