Abstract
Polymer/transition metal salt composite nanofibers have gained considerable attention in recent years. Doping of transition metal salt into the polymer matrix allows the fabrication of nanofibers with special functions. This goal of this study is to develop PVP/Cu2+ composite nanofibers for potential optical application. In this study, polyvinylpyrrolidone(PVP)/Cu2+ nanofibers with diameter of 200-900 nm were fabricated by electrospinning. Coper(II) nitrate trihydrate was added to PVP electrospinning solution. The electrospun nanofibers were characterized by scanning electron microscope(SEM), energy dispersive microscopy(EDS), and ultraviolet-visible spectroscopy(UV-vis). The results indicate that Cu2+ was successfully doped into PVP system and the electrospun PVP/ Cu2+ nanofibers show a board band at 780nm on the absorption spectrum. It also suggest that the fibers became fine and had higher absorption intensity with PVP/Cu(NO3)2 weight ratio decreasing. | 52 pages
