This could be due to the low concentration of polymer, which does not maintain the formation of a proper Taylor cone. The low concentration may not attain the suitable viscosity to form a fiber.

Protrusions in electrospun keratin nanofibers at low polymer concentrations can arise from reduced viscosity, jet instability, and rapid solvent evaporation. Optimizing electrospinning parameters and slightly increasing polymer concentration may help improve fiber uniformity.
