The PAN and Zeolite solution were prepared by mixing as the ratios of 0, 0.5, 1, 2 wt.% zeolite in 10 wt.% PAN solution. The webs were prepared by electrospinning, stabilized at 280℃ in the air atmosphere, and activated at 800℃ in the nitrogen by 30 vol. % steam. In result, average diameter of activated carbon nanofibers (ACFs) was 350 50 nm. The average pore diameter and specific surface areas were 1.8 ~ 2.7 nm and 742 ~1145 m2/g, respectively. When zeolite was added into the activated carbon nanofibers (ACFs), the specific capacitance was increased. This result attributes to a pore of the zeolite. The pore of zeolite made the specific surface areas and capacitance increase. |
