Fig. 3. The morphology and diameter of nanofiber membranes.
a The appearance of nanofiber membranes fabricated by PLA and different concentrations of PEGDA-EDT was observed by SEM (Scale bar, 5 µm). b The morphological features and average diameters of P, PF, PGF, PPF, and PPGF nanofiber membranes (Original low magnification: scale bar, 200 μm; original high magnification: scale bar, 5 μm). c The diameter distribution of P, PF, PGF, PPF, and PPGF nanofiber membranes was calculated according to b.
