Carbon nanofiber from deacetylated cellulose acetate prepared by direct fluorination |
| 초록 |
In this study, cellulose based carbon nanofiber has been fabricated by electrospinning from cellulose acetate (CA) followed by fluorination and carbonization at 800 ℃ for 1 h. The properties of the fluorinated electrospun CA nanofibers have been analyzed by scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS) and thermo-gravimetric analysis (TGA). Fluorine functional group in CA nanofiber is introduced by fluorination which has caused deacetylation on cellulose acetate fiber. This deacetylation of CA fiber has prevented from melting of cellulose acetate during carbonization process. The introduced fluorine functional groups have also increased thermal stability and carbonization yield of CA fiber. |
