Optimization of Fiber Diameter in Gelatin/Chitosan Electrospinning Process

Electrospinning is a very useful technique for producing polymeric nano fibers by applying electrostatic forces. This study reports on the modeling and optimization of electrospinning process of gelatin/chitosan, using response surface methodology. Gelatin/chitosan blend ratio (50/50, 60/40 and 70/30), applied voltage (20, 25 and 30kV) and feeding rate (0.2, 0.4 and 0.6 mL/hr), their individual and interaction effects on the mean fiber diameter (MFD) were investigated. The model obtained for MFD has a quadratic relationship with applied voltage and feeding rate
