Electrospun Gelatin Fiber Bundles by Self-Bundling Electrospinning

Abstract:

Electrospun gelatin fiber bundles were successfully prepared by self-bundling electrospinning process. A solvent mixture of 80:20 v/v acetic acid: N,N-dimethylacetamide was used as solvent for gelatin. Self-bundling was achieved by using of a grounded needle tip at the beginning of electrospinning process. Gelatin fiber bundles were fabricated from 30% w/v gelatin solutions with addition of pyridinium formate (PF) at concentrations of 3 and 5% w/v. The averaged diameters of single fiber were 452 and 410 nm, respectively; whereas, the averaged diameter of bundles were 17.2 and 22.3 μm, respectively. Viscosity and electrical conductivity of solutions were important parameters for achieving self-bundling electrospinning. Gelatin solutions with optimum electrical conductivity and viscosity could yield bundles by self-bundling electrospinning.
