Abstract
Polyaniline (PANI) Polyvinyl Acetate (PVAc) nanofibers were fabricated via electrospinning from doped and undoped PANI-PVAc solution of different viscosities. The effects of viscosity on the morphological characteristics of PANI-PVAc nanofibers were investigated using Scanning Electron Microscopy. From the micrographs, average fiber diameter and fiber length, as well as the average bead diameter and bead length were determined. It was found that the fiber length increases while the fiber diameter decreases when the viscosity of the undoped solution decreases from 140.00P to 41.60P. The bead size increases when the viscosity is decreased from 41.60P to 15.20P. For doped samples, the bead diameter. bead length. fiber diameter and fiber length increases when the viscosity of the solution decreases.
