Polyacrylonitrile‐based electrospun carbon paper for electrode applications

摘要: Polyacrylonitrile (PAN)-based carbon paper with fiber diameters of 200–300 nm was developed through hot-pressing, pre-oxidation, and carbonization electrospun mats. Changes in morphology, crystallinity, surface chemistry the hot-pressed were investigated. More junctions between fibers formed increasing hot-press time, which is attributed to melting bonding fibers. The bulk density increased 0.5–0.6 g/cm3, could help improve volume energy for electrode applications. conductivity found be about 40 S/cm when area ∼ 2 m2/g, depends not only on individual nanofibers but also contacts nanofibers. performance as an electrochemical reactions involving ferrocene molecules affected by preparation protocol: higher electrodes shorter times provided a current generated per unit mass than that obtained prepared using longer exhibited electrical faster electron transfer kinetics. © 2011 Wiley Periodicals, Inc.
