Influence of gelatin type on physicochemical properties of electrospun nanofibers


This study explores the fabrication of nanofbers using diferent types of gelatins, including bovine, porcine, and fsh gelatins. The gelatins exhibited distinct molecular weights and apparent viscosity values, leading to diferent entanglement behavior and nanofber production. The electrospinning technique produced nanofbers with diameters from 47 to 274 nm. The electrospinning process induced conformational changes, reducing the overall crystallinity of the gelatin samples. However, porcine gelatin nanofbers exhibited enhanced molecular ordering. These fndings highlight the potential of diferent gelatin types to produce nanofbers with distinct physicochemical properties. Overall, this study sheds light on the relationship between gelatin properties, electrospinning process conditions, and the resulting nanofber characteristics, providing insights for tailored applications in various felds.
