Fluorescence Properties of Electrospun Bio-Based Polyamide/Eu(TTA)3phen Composite Fibers

Article Preview

Abstract:

In this paper, the bio-based aliphatic copolyamide (bio-based PA) was synthesized by bio-based diacids and diamines, and Eu (TTA)3phen of Lanthanide complexes was synthesized. Then bio-based polyamide/rare earth composite fibers were prepared by electrospinning method. The structure and properties of the electrospun composite fibers were characterized by fluorescence photometer, x-ray diffraction (XRD), scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FTIR). The results showed that, with the increase of the content of rare earth, the fluorescent intensity of bio-based polyamide/rare earth composite fibers first increased, and then decreased. When the content of rare earth was 10%wt, the fluorescence property of the electrospun composites was best.
