Preparation and characterization of polyacrylonitrile-based porous carbon nanofibers by ZnCl2 activation |
| 초록 |
The effects of ZnCl2 content and activation time on pore development of porous carbon nanofibers prepared from electrospun polyacrylonitrile (PAN) nanofibers (10 wt.% in DMF) were investigated. Morphological and structural properties after ZnCl2 activation were observed using scanning electron microscopy and X-ray diffraction, respectively. N2 adsorption isotherm characteristics at 77K were employed for textural properties of the porous carbon nanofibers. Specific surface areas and total pore volume of the porous carbons were determined as 600~1290 m2/g and 0.24~0.54 cm3/g, respectively. It was also observed that various pore size distribution were found to be depended on the functions of ZnCl2 content and activation time. |
