Thin, bendable electrodes consisting of porous carbon nanofibers via the electrospinning of polyacrylonitrile containing tetraethoxy orthosilicate for supercapacitor
Abstract.
In the present study, electrically conducting carbon nanofiber (CNF) mats were produced by incorporating
tetraethoxy orthosilicate (TEOS) into polyacrylonitrile (PAN) via electrospinning. A simple thermal treatment
was applied to the electrospun nanofibers to create ultramicropores that could accommodate a large number
of ions were formed on the surface of the CNFs, removing the need for a time-consuming activation step. The
Si/CNF composites showed high capacitance and energy/power density values due to the formation of
ultramicropores and the introduction of heteroatoms.
