Abstract
In this research, gallic acid-loaded electrospun cellulose acetate (CA) fibers were prepared. The average diameters of gallic acid-loaded CA fibers ranged between 702-1280 nm. Electrospun CA fibers containing 2.5% gallic acid had smooth surfaces, but gallic acid flakes were observed on the fiber surfaces with increasing gallic acid content. The effect of electrospinning processing parameters such as electrostatic potential and electrospinning distance on fiber morphology was also investigated. However, it exhibited less significant effect than gallic acid concentration. To obtain the desired gallic acid-loaded CA electrospun fiber with smooth and uniform the suitable electrospinning condition should be: electrical potential 12 kV and the electrospinning distance of 12.5 cm.
