In this work, mesoporous carbon fibers were prepared by electrospinning and physical activation. The polystyrene used as a precursor of carbon fibers was prepared with treatment for improvement of low carbon yield of polystyrene. In order to develop mesoporous structure, silica was used as a physical activation agent owing to the meso-size particles. Textural properties of the carbon fibers were evaluated using the surface pore structure analysis apparatus. The experimental results indicated that the diameter of the fibers increased and the surface became more irregular after physical activation. Also, the specific surface area increased and total pore volume increased through physical activation using the silica. Consequently, the activated carbon fibers having broad meso-sized pores were obtained successfully. |
