چکیده انگلیسی


• PSU/Ni nanofibers have been fabricated by electrospinning method.
• The structural, morphological and optical properties were investigated.
• The fluorescence spectra of PSU/Ni nanofibers were analyzed.
• Two average lifetimes with a short decay time, τ1 and a long decay time, τ2 were obtained.

One-dimensional polysulfone/nickel fibers with different content of nickel nanoparticles were prepared by electrospinning method. The contact angles and wettability of the resulting fibers were determined by static water contact angle method. The experimental results revealed that values of contact angle of the fibers were affected by composition of the fibers. In the photoluminescence spectra of the PSU/Ni nanocomposites an emission band located in the range 346–362 nm was observed, which was progressively shifted toward the shorter wavelengths, as the nickel content increased. Two average lifetimes with a short decay time, τ1 (contributions of this component is 56.01–87.15%) and a long decay time, τ2 (with the slow decay contribution 12.85–40.28%) were obtained. The content of Ni from polysulfone fibers determine the photophysical and surface characteristics.
