Tensile and viscoelastic properties of PCL/PEG-NB coaxially-structured fibrous scaffolds polymerized with different UV doses. (A) Representative stress-strain curves of coaxial PCL/PEG-NB fiber scaffolds polymerized with high UV dose, which are compared with the PCL fiber scaffold. (B) Representative strain sweep results of G’ and G”, from the rheometer measurements of PCL/PEG-NB 10k. (C) Storage modulus, G’, of coaxial fiber scaffolds with PEG-NB 5k or 10k. ‘*’: comparing vs. low UV dose.
