| Outline of Final Research Achievements |
Poly(vinyl alcohol) (PVA) is a low-cost and water-soluble polymer. We have developed an environmental-benign method to fabricate porous carbon nanofibers from PVA. Carbon nanofibers were fabricated by electrospinning an aqueous solution of PVA, diammonium hydrogen phosphate (DAP) as a carbonization agent, and a cationic surfactant, sodium dodecyl sulfate (SDS), followed by the carbonization. The salt particles were formed by the decomposition of DAP and SDS during the thermal treatment and served as templates for the formation of pores inside of carbon nanofibers. The applicability of the carbon nanofiber as the electrode of electric double layer capacitor was investigated. The inner pore structure contributed to the decrease of internal resistance. We could also fabricate the porous carbon nanofiber using an aqueous solution of PVA and sodium monododecyl phosphate (SMDP), which served as the carbonization agent as well as the template.
