  • Fabrication of nonwoven fibrous membranes with controlled fiber diameters (1-5 micrometers).

    • Main Results:

    • Lecithin concentration influenced micellar morphology from spherical to entangled cylindrical.
    • Entangled wormlike micelles enabled electrospun fiber formation.
    • Successful fabrication of nonwoven phospholipid membranes in a single step.

    Conclusions:

    • Electrospinning of lecithin is a viable single-step method for creating nonwoven fibrous membranes.
    • The process allows for the formation of biologically based, high-surface-area materials.
    • This approach avoids complex designs and postprocessing, offering a simpler alternative.
