摘要
Poly vinyl alcohol(PVA)is a material generally used in glue.To use thermoplastic resin for a carbon material has not been focused due to its low carbonization yield.However,it has been reported that the carbonization yield is improved up to about 30% by pretreatment with iodine vapor1.Since PVA is a water-soluble polymer and easily forms a mixture with other water-soluble substances,it is likely to provide environmental friendly CNF preparation method.In this study,PVA nanofibers were prepared by electrospinning from PVA aqueous solution containing potassium iodine(KI),and carbon nanofibers(CNFs)were prepared without iodine vapor pretreatment.Electrochemical characteristics of CNF were evaluated for an electric double-layer capacitor(EDLC).This study gives ecofriendly CNF preparation method.
