Ni-fluorinated vapor growth carbon fiber (VGCF) composite films prepared by an electrochemical deposition process

Abstract

Nickel-fluorinated vapor growth carbon fiber (VGCF) composite films have been fabricated by using electrochemical deposition method from the plating bath containing a cationic fluorocarbon surfactant as the dispersing agent of fluorinated VGCF. The ESCA result confirmed the existence of metallic Ni and the fluorinated VGCF with C–F covalent bond structure in the composite film, while the SEM and TEM results showed that the fluorinated VGCFs embedded into the Ni-fluorinated VGCF composite film obtained from the plating bath at a dispersion concentration of 2.5 g dm −3 VGCF. The results clearly proved that the bath concentration and deposition conditions, which were designed in the present study, are effective on preparing the Ni-fluorinated VGCF composite film.
