Abstract
Nanofibers of poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT) and poly(ethylene 2,6-naphtalene dicarboxylate) (PEN) were prepared by electrospinning, and the resulting morphologies were investigated by polarizing optical microscopy, scanning electron microscopy and transmission electron microscopy. The major technological parameters (the concentration of polymer solution and the electrical field strength) which influence morphology of the obtained fibers were examined. PET, PBT and PEN nanofibers without beads were prepared by appropriately setting these parameters. In order to align and collect nanofibers parallel to each other, we used the homemade collector with parallel electrodes. The selected-area electron diffraction of nanofibers, which were drawn and/or heat-treated with being as-deposited on the collector, showed a well-developed fiber pattern.
