Abstract
Abstract Electrospinning was employed to produce composite fibers mat consisting of PVP (polyvinylpyrrolidone)/CA (cellulose acetate) and garlic extract. The electrospun nanofiber mats for all variations had a uniform and beaded free fibers. The average fiber diameter of composite fiber increased when the applied voltage was increased from 12 to 14 kV. However, the average diameter reduced when the applied voltage was larger than 14 kV. During the electrospinning process, the condition of cone jet in the tip of the needle was recorded and it was confirmed that when the applied voltage was from 12 to 14 kV there is intermittent squirt of solution indicating that the removal rate of the solution due to the applied voltage is smaller than the feed rate of solution. The time interval between squirts increased as the applied voltage was increased from 12 to 14 kV, while there is no squirt for applied voltage larger 14 kV.
