Electrospinning is the favorite process to fabricate fibres with diameter in the range nanoscale through the action of electric field. In this study, 3-7% chitosan, 18.0% cellulose acetate and 30.0% gelatin solution in aqueous 80% acetic acid solution were blended at the volume ratio of 4:1:5 have been successfully electrospun. The effect of processing parameters and the concentration of the polymer solution on the morphology and diameter of electrospun were investigated. The morphology and diameter of electrospun fibres were observed by scanning electron microscope. The diameters of chitosan-cellulose acetate-gelatin nanofibres ranging from 78.94 to 421.05 nm. The results showed that the fibre diameters increased when the solution concentration and flow rate were increased, whereas the fibre diameters decreased when the applied voltage and distance between tip to collector were increased. The conditions of the solution concentration 18.8 %wt, applied voltage at 23 kV, flow rate at 11.67 μL/min and collector distance at 10 cm were selected to prepares the desirable electrospun nanofibres for applications and the further research.
