Blending salmon gelatin with polyvinylidene fluoride using coaxial electrospinning.

ABSTRACT: Electrospinning is a technique that produces large quantities of nanofibers, that can be designed at the molecular level. Electrospun membranes can be designed to biomimic the chemical composition and morphological structure of the extracellular matrix. Here, we blend salmon gelatin with polyvinyl alcohol and chitosan, which are electrospun in a coaxial configuration with polyvinylidene fluoride, a piezoelectric polymer. We obtain membranes with two size distributions, a large nanofiber distribution with a mean diameter of 426 ±142 nm and a small nanofiber distribution with a diameter of 251 ±49 nm. Nanomechanical characterization of the large nanofibers reveals two Young's moduli peaks centered at 1.77 ±0.05 GPa and 209±126 MPa. Small nanofibers also show a two component mechanical moduli
