Electrospun materials properties. a Water contact angles of the electrospun NFs with and without the antimicrobial agents and the drug-containing core/shell NFs. b FTIR-ATR spectra, c Representative tensile stress–strain curves of the drug-containing, drug-free, and core/shell electrospun mats. d Young's modulus and e Ultimate tensile strength of the drug-containing and core/shell NFs. Error bars = standard deviations, where star symbols indicate significant difference p-values, *** p < 0.001 and * p < 0.05. *Core/shell is PA6-PHMB/CS-5CLO8Q
