Abstract

The effects of applied voltage on the mean diameter of electrospun polyaniline-elastomeric adhesive fibers were investigated. Polymeric solutions composed of equal volume of dimethyl sulphoxide-dissolved polyaniline and elastomeric adhesive were prepared. These solutions were drawn into fibers by electrospinning with different applied voltages of 20, 30, 40, 50, and 60 kV. Scanning Electron Microscopy (SEM) images, together with fiber diameter measurements, showed that as the applied voltage was increased, the mean fiber diameter of the electrospun fibers also increased. The increase in mean fiber diameters was attributed to shortened flight time of the jets produced during electrospinning, increased deposition rate and bead formation, which contributed to the increase in fiber diameters.
