Physical and mass transfer properties of electrospun ɛ-polycaprolactone nanofiber membranes

- Physical and mass transfer properties of electrospun membranes were assessed.
- Membrane properties were affected by trypsin encapsulation.
- Compounds' molecular weight proved to be determinant in transport properties.
- Mass transfer by relaxation is higher than by Fick's transport for both membranes.
- Relaxation of polymer is important for designing a functional electrospun membrane.
