Figure 20

Schematic representation of (a) the coaxial and (b) conventional electrospinning process for the fabrication of nanofiber membrane, (c) fabrication steps of the asymmetric PVDF-co-PDMS nanofiber membranes (PVDF-co-PDMS-AS). The red nanofibers, blue microspheres, and brown substrate represent the PVDF selective layer, PDMS-based nanoparticles, and PVDF substrate, respectively. (Reprinted with permission from [129].
