The effect of fluorine functional groups on carbonization of cellulose fibers |
| 초록 |
Fluorine functional groups in cellulose fibers were introduced by fluorination for increasing of carbonization yield. The surface functional groups and thermal properties of fluorinated cellulose fibers were analyzed by X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA), respectively. Carbonization of fluorinated cellulose fibers was accomplished in N2 gas at 800 ℃ for 1h, and the carbonization yield was measured. The content of fluorine functional groups in fluorinated cellulose fibers was increased according to increasing of fluorination temperature. However in high fluorination temperature (at 180 ℃), the content of fluorine functional groups was decreased by the high heat energy during fluorination. Introduced fluorine functional groups increases the carbonization yield of cellulose fibers by increasing of double bond (C=C bond). The carbonization yield was increased 52.5% compared to pure cellulose fibers by fluorination at 120 ℃. |
