Electrophoretic deposition of network-like carbon nanofiber as a conducting
substrate for nanostructured nickel oxide electrode
Abstract
A vapor-grown carbon nanofiber (VGCF) film with network-like architecture
was fabricated by electrophoretic deposition (EPD) in the isopropanol suspension
containing Ni(NO3)2 additive. Nickel ions adsorbed on the VGCFs increase the zeta
potential of VGCFs, consequently, the EPD rate and nanofiber dispersion are
remarkably improved. Nickel deposition is accompanied by reducing the nickel ions
on the surface of VGCFs. Nickel appears to be suitable as a conducting metal binder
for attaching the VGCFs. EPD of the nickel oxide on VGCF-coated film exhibits
excellent capacitive behavior compared with that bare NiO electrode, resulting from
the reduced electron conducting and charge-transfer resistances.
