Abstract
Fabrication of Polyaniline (PANi)-Polyvinyl Chloride (PVC) nanabers was done using electrospinning method. PANi was blended with PVC in a 66.67%-33.33% (PANi-PVC) solution ratio. The distance between the needle tip and collector was varied from 4 to 18 cm with 2cm increment. Results show that as the distance between the needle-tip and collector increases the diameter of the fiber decreases both for PANi-ES-PVC and PANi-EB-PVC, with correlation value r equal to —0.906 and —0.919, respectively. These indicate a strong relationship between the distance of needle tip to collector and the diameter of the fibers. The working distance that yields the smallest fiber diameter of 212.8 + 7.5% nm is 16cm. At 18 cm the fiber diameter increases again suggesting that the distance between the needle-tip and collector has a limiting value. Further increase of the tip to collector distance yields an unspinnable polymer solution. It has also been found that a more conductive solution yields smaller fibers and has a larger fiber mesh diameter. The fiber mesh diameter has been found to be linearly dependent on the distance of the needle tip and the collector.
