In this study, the nano fibers having an alignment were prepared by electrospinning process, using different collectors made from various materials and collecting methods. A spinning solution was prepared by dissolving poly(arcrylronitrile) (PAN) in DMF. And the fibrous were obserbed by SEM. As a result, a sort of materials of collectors and the collecting methods had not greatly influenced on the average diameters of fibers but the forms of them. The just accumulated nano-fibers on the collectors formed net structures, which had no alignment. On the contrary, the continuously collected nano-fibers formed long fibers with alignment. |
