The activated carbon nanofiber (ACNF) were prepared by stabilizing at 280℃ in the air atmosphere and activating at 1000℃ in the nitrogen atmosphere the fibers prepared by electrospinning of polyacrylonitrile (PAN) and polycarbonate (PC) blending polymer solution in DMF. The average diameter of ACNF was about 400 nm. The specific capacitance of pure PAN was 141 F/g, while that of ACNF on the basis of PAN/PC at the weight ratio of 7 to 3 was 186 F/g, as increased 32 %. This was ascribed to the increase of specific surface area and pore diameter, oxygen functional groups and surplus electron. |
