更新时间:2023-05-28

【摘要】The luminescent fibers have a good application prospect. The feature of this paper is that efficient luminescent nylon 6（PA6） composite nanofibers are successfully prepared by electrospinning. The luminescent PA6 composite nanofibers composed of PA6, Eu（BA）3Phen and Tb（BAO）3Phen（BA= P-methylbenzoic acid, BAO=P-methoxybenzoic acid, and Phen=1,10-phenanthroline）. The structure and properties were characterized by scanning electron microscopy（SEM）, Fourier transform infrared spectroscopy（FT-IR）, fluorescence spectroscopy, and thermogravimetriy（TG） analysis. The correspondence between polymer matrix and as-prepared composite nanofibers properties has also been studied in detail. Through using hexafluoroisopropanol（HFIP） as solvent, Eu（BA）3Phen/PA6 and Tb（BAO）3Phen/PA6 composite nanofibers exhibit good luminescence properties. It is noted that only 5% rare earth luminescent materials are added to Tb（BAO）3Phen/PA6 composite nanofibers, and the luminescence intensity of the as-prepared nanofibers reaches half that of the pure rare earth luminescent materials. Furthermore, uniform dispersion of pure rare earth luminescent materials in the as-prepared nanofibers gives the composite nanofibers good mechanical properties and thermal stability. These results provide an important basis for the preparation and wide application of new PA6 luminescent fibers.
