Material characterization of ZnCS sandwich-structured wound dressing (ZnCS-SWD) (PLA fiber membrane was used for comparison). (a) The macroscopic appearance of the ZnCS-SWD. (b) The SEM of the ZnCS-SWD (Outside: the side not in contact with the ceramic powders; Inside: the side directly in contact with the ceramic powders). (c) Photos of the water contact angle of the ZnCS-SWD surface. (d) Quantitation of the contact angle of the ZnCS-SWD. (e) The water absorption performance of the ZnCS-SWD (1*1 cm2) with different amount of bioceramic powders. (f) The ion release of the ZnCS-SWD (1*1 cm2) by soaking in PBS at 37 °C for 24 h.
