Preparation of poly(ether sulfone) ion-exchange nanofibers by electrospinning and their adsorption properties |
| 초록 |
Poly(eter sulfone) ion-exchage fiber were prepared by electrospinning. Thier adsorption properties were investigated. The change of fiber's thickness was influenced by Tip to collector distance (TCD), voltage and flow rate. The fibers were formed at the low concentration of PES, while the thickness of fiber incresed at the high concentration of PES. Functional group was introduced to PES fibers by sulfonation. It is confirmed that -SO3H group was introduced to the fibers by FT-IR. Degree of sulfonation was proportionate to the concentration of chlorosulfonic acid. The ion exchange capacity and water uptake were dependant on the degree of sulfonation. we observed a slight increasing trend as well. |
