Abstract

Ultrafine fibers having approximately 800 nm diameter were prepared by an electrospinning method from cellulose acetate. Cellulose acetate dissolved in acetone solutions were electrospun at various conditions. The cellulose polymer solutions of various concentrations were applied under different voltages, flow rates, and tip-to-collector distances (TCD). The diameter of fibers depended on the electrospinning parameters such as its viscosity. The fibers were not formed from the polymer solutions less than 12.0 cP viscosity. The minimum diameter was 800 nm at 12.5 wt% of polymer concentration, 12 kV of voltage, $100{\mu}L/min$ of flow rate, and 7.5 cm TCD.
