Preparation of the porous nanofiber webs of binary blend system using a differences of miscibility |
| 초록 |
The aim was to determine the morphology development of polymer blend fiber webs using miscibility difference of PAN and other polymers. PMMA and PAA were selected as Pyrolyzing polymers due to its solubility parameters. PMMA have a huge difference with PAN compared to PAA. The 10wt% PAN and 25wt% of Poly(methyl methacrylate) (PMMA) and poly(acrylic acid)(PAA) were dissolved in DMF. PMMA and PAA blends based on PAN were prepared in a 75:25 ratio, blend nanofiber webs were prepared by electrospinning process. And PMMA and PAA were removed at a high temperature in N2 atmosphere. The morphology and diameter of fibers were investigated using scanning electron microscope. As changed miscibility of blends, the morphology and pore structures of blend fiber webs were controlled in various forms. |
