Ft Ir Spectroscopy

We studied the effect of gap size on molecular orientation and crystalline structure of theuniaxially well-aligned nylon 6 nanofibers produced in the gap of the negatively charged metal plates. As evidenced by polarized FT-IR spectroscopy, relative intensity in several absorbance bands, including the N-H stretching, amide I, II, and III vibrations were found to be different in the parallel and perpendicular polarized FT-IR spectra. Moreover, X-ray analysis indicated that the metastable γ-form was predominant in the as-spun nylon 6 nanofiber, and was transformed into the thermodynamically stable α-form by increasing the cap size. These results suggested that the polymer chains were oriented perpendicular to the fiber direction. Molecular orientation to the fiber axis was enhanced as increasing the gap size.

In order to release the relationship between technics variables and properties of PAN fiber, the evolvement of crystalline structure of PAN fiber during the wet spinning process was studied by X-ray diffraction(XRD), the measurement of the solvent residuals, boiling-water shrinkage and breaking tenacity. It is found that the drawing and removal of solvent can improve the tenacity, especially the drawing can improve degree of orientation and crystallinity, and the collapse process can stabilize the orientation and crystalline structure.
