Electrochemical property of carbon nano-composite prepared via high dispersion of vapor-grown carbon fiber by addition of polyfluorene

Vapor-grown carbon fibers (VGCFs) were successfully dispersed by addition of polyfluorene (PF) in THE solvent without any reduction in length of the VGCFs. Degree of dispersion of the VGCFs in the solvent was enhanced as a ratio of PF to VGCF increases in the ratio ranged from 1/5 to 5/1, probably because of a polymer wrapping effect of the PF onto the surface of the VGCF. The dispersed PF-coated VGCFs (VGCF/PF) led to fabricate uniformly-coated electrodes because of their high dispersibility. Discharge behaviors of the VGCF/PF-based electrodes were also discussed in order to confirm feasibility of the VGCF/PF as an electroactive nano-composite.
