Preparation and physiochemical properties of electrospun nanofiber membranes. Schematic of electrospun nanofiber membrane preparation (A). SEM images of electrospun nanofiber membranes (B) with nanofiber diameter distribution (C). FTIR spectra, (D) and XRD patterns (E), water contact angle (F), mechanical properties (G), water absorption rate (H), moisturizing rate (I), in vitro degradation (J), and drug release profile (K) of electrospun nanofiber membranes. *p < 0.05, **p < 0.01, and ***p < 0.001, and n.s., not significant
