Physical and electrochemical studies of polyphenylsilane-derived porous carbon nanofibers produced via electrospinning
Abstract.
Polyacrylonitrile (PAN)/polyphenylsilane (PPS)-based composite carbon nanofibers (CCNFs) are prepared
by one-step electrospinning and subsequent thermal treatment to produce organic-inorganic hybrid
CCNFs. We investigate the electrochemical behavior and structural properties of these CCNF materials
as a function the PAN/PPS ratio. The CCNFs show large specific surface area, high electrical conductivity
and high thermal stability. In addition, the electrochemical performance of the organic–inorganic hybrid
CCNF electrode is improved by the special porous structure and the silicon oxycarbide (Si–O–C)-related
structure.
