Preparation and characterization of high aspect ratio nanofibers in polyamide-6 by using electrospinning |
| 초록 |
we report on the high aspect ratio polyamide-6 nanofibers prepared by using electrospinning technique. The morphological, structural characterizations and thermal properties of the polyamide-6 nanofibers were determined using field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), thermogravimetry (TGA), Raman spectroscopy, Fourier transform-infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM). In order to accurately characterize the high aspect ratio nanofiber structure by the direct identification of mass resolved chains, we performed matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF). FE-SEM images revealed that high aspect ratio polyamide-6 nanofibers bound between the main fibers. The diameter of the polyamide-6 nanofibers were observed to be in the range of 75 to 110 nm, whereas the high aspect ratio structures consisted of regularly distributed very fine nanofibers with diameters of about 9 to 28 nm. |
