Abstract

PVA/cobalt acetate/zinc acetate doped with boron composite fibers were prepared by electrospinning technique. Electrospinning was performed by putting solutions at different applied voltage in a range from 13 to 18 kV. The fibers were measured and characterized by viscometer, conductiometer with fourpoint probe , Fourier transformed infrared spectroscopy FT-IR , scanning electron microscopy SEM , and differential scanning calorimetry DSC . The viscosity of the Boron doped solution was higher and favoring the formation of thinner and uniform nanofibers. DSC analysis shows that when boron is added to the polymer it increases the crosslinking and amorphous structure of PVA/ cobalt and zinc acetate composite polymer is increased.
